Urban physical development in Indonesia can lead to an increase in urban air temperatures which generally have higher temperatures than in rural areas and can be outside the standard of human thermal comfort. Thermal comfort is a way for humans to respond to stimuli to the temperature of the surrounding environment. Vegetation has an important role in controlling the comfort of thermal microclimates, namely modifying air temperature, controlling humidity, reducing solar radiation and regulating wind speed. The Ria Rio Reservoir area in the DKI Jakarta province, is in an urban environment with a high population and dense building. The purpose of this study is to measure the amount of vegetation function towards thermal comfort in the Ria Rio Reservoir area. The research method used is descriptive qualitative and quantitative methods. Measurement of thermal comfort in the area is done by direct observation. Assessment of vegetation function as a modification of the microclimate will be assessed quantitatively using the Key Performance Index to see how large the function of vegetation is in thermal comfort. The results of the study are the magnitude of the value of vegetation comfort as a thermal comfort control in determining the criteria for selecting plants in the regional landscape design.

Cotton, popularly called as “white gold” is a leading commercial crop grown world over for its valuable fibre. India has become the global leading grower and largest producer of cotton. However, the growth rate in area, production and yield in the current decade has registered a reduced growth rate. Hence it necessitates a study to analyse the factors responsible for such changes. The ‘Total Factor Productivity’ (TFP) approach is considered as suitable tool to examine the growth in agricultural productivity and to separate out the effect of inputs and other factors like technology, infrastructure etc., on productivity growth. The study utilizes Tornqvist – Theil index for calculation of total factor productivity. Time series data from various published sources were collected for the period 1970 to 2017-18. The results have shown a declining trend in growth of Total Input Index, Total Output Index and TFP. Declined growth of TFP indicated the negative impact of technological changes on cotton. The study has suggested for more research and policy measures to impede the declining trend in TFP of cotton in the state.

As a megadiverse country, Indonesia should be able to take advantage of its biodiversity richness optimally for national purposes. This paper discussed current issues of freshwater fish genetic resources, regulations, and governance policies, as well as its preservation and utilization programs. The main global issues of extinction of genetic resources due to habitat degradation, over-exploitation, water pollution, invasive species, and climate change have also occurred in Indonesian waters. Indonesia has ratified international agreements relating to biological diversity, biosafety, access and benefit-sharing of genetic resources, Specific regulation on conservation of fish genetic resources has appeared in the conservation of its ecosystems, species, and populations. The Indonesian Ministry of National Development Planning (IMNDP) has drawn up a strategic action plan on biological resources management. At the central level, in addition to the Ministry of Environment and Forestry (MEF), the Ministry of Marine Affairs and Fisheries (MMAF) is determined as management authority, and the Indonesian Academy of Sciences (IAS) is appointed as scientific authority. Local government consisting of provincial and district/city governments can manage water areas be managed of water areas in their jurisdiction based on assessment and approval of MMAF. Aquatic habitat conservation of the freshwater ecosystem needs to be improved to support the domestication program and cultivation of endemic species to ensure the sustainability of fish population. From the study, it can be concluded that management and strategic planning of conservation need to be implemented properly through strengthening legislation, policy development, and its implementations to broader communities, improving synergic coordination among institutions and stakeholders, and training and education of conservation staffs in advanced technology for genetic preservation and utilization.

Sweet potato (Ipomoea batatas [L.] Lam.) is one of the most important staple crops globally with particular cultural and economic significance in the Hawaiian Islands, yet the extent to which traditional cultivars persist remains unknown. The objective of this study was to elucidate the relationships between traditional Hawaiian sweet potato varieties and cultivars that originated elsewhere in the world. We sought to characterize genetic and phenotypic diversity of sweet potatoes represented in the Hawaiian Islands. To this end, a genetic assignment analysis was conducted on a sample of 77 individuals that consisted of traditional Hawaiian, USDA NPGS accessions, and recent herbarium samples. Additionally, voucher specimens of Hawaiian cultivars from the early twentieth century were assessed for variation in leaf morphology. We identified several inconsistencies within the Hawaiian-named varieties, as identically named varieties turned out to be genetically distinct, and similarly named voucher specimens varied in leaf morphology. Our findings call attention to the value of a set of Hawaiian sweet potatoes as “heirloom.” These genetically distinct traditional cultivars have unique value in local markets and present an opportunity to increase cultivar diversity in the markets and fields, support farmer income and diversified agriculture, all while contributing to reinvigoration of Hawaiian cultural heritage.

This study presents preliminary results from a phytolith analysis of carbonized food residues and sediment soils from sites in southern New England (Connecticut and Rhode Island) dating 2500–500 BP. Phytolith analyses of carbonized food residues from sites across northeastern North America outside of southern New England demonstrate that maize (Zea mays L.) was introduced to the region as early as 2300 BP, hundreds of years before major shifts in settlement strategies became widespread. Phytolith evidence for maize in eastern North America likewise appears hundreds of years earlier than most maize macroremains, such as kernels, cobs, and cupules, appear. This has puzzled researchers attempting to piece together how maize was first circulated and used in the Eastern Woodlands. Preliminary phytolith analysis of carbonized food residues from seven sites indicates that, consistent with research outside the study area, at least some groups in southern New England cooked maize as early as 2300 BP. The results also indicate that maize cooking practices varied in ways that likely reflect broader subsistence strategies and that may explain the temporal gap between maize phytoliths and maize macroremains.

Econ Bot 2021, 75(1), 1-29.
Rice (Oryza spp.) is an important food and cash crop in the Republic of Benin. However, despite its production increase in recent years, the yield of cultivated varieties remains low, and the introduction of improved varieties threatens the rice diversity existing in traditional agriculture. Therefore, documenting the on-farm management of rice diversity, farmers’ varietal preferences, and their perceptions of the performance of cultivated varieties and species are important prerequisites for the development of on-site breeding and conservation programs. To fill these gaps in Benin, 418 rice farmers, belonging to 21 ethnic groups, were surveyed in 39 villages using participatory rural appraisal tools. Subject to synonymy, 30 improved varieties and 68 local varieties were registered and their folk nomenclature and taxonomy were documented. The north of Benin had the highest diversity of rice with the greatest number of traditional varieties, making this region the best place for an in situ conservation program. The number of rice varieties maintained per village varied from 1 to 15 (six on average). The foursquare analysis revealed that the improved variety IR 841 was by far the most popular variety. Most of NERICA varieties were abandoned in the south, while the north still hosts a wide range of local varieties. Twenty-one reasons explained varietal abandonment by farmers, varying according to geographic areas and ethnic groups. The seed system was both formal and informal in the study area. The participatory evaluation revealed the necessity to create and introduce tolerant/resistant rice varieties to drought and flooding stresses in Beninese agriculture that meet farmers’ preferences. Our results showed that north Benin would be the most suitable place for in situ conservation of local rice diversity.

Forest vegetation plays an important role in the vast and complex relationship between biotic and abiotic components of the environment. In this study, we aim to construct a baseline analysis on the inf luence of forest in modifying soil and air temperature as well as the filtration capacity of the forest canopy. Results showed that forest microclimatic air and soil temperatures were significantly lower as compared to an open grassland ecosystem. Tree canopies and vegetation play a significant role in reducing the effects of heat in open outdoor spaces by filtering the incoming solar radiation before it reaches the ground surface. Litter decomposition on the other hand is an important biogeochemical process in terrestrial ecosystems. We compared the decomposition rates of the two ecosystems on surface floor litterbags and results showed that forest decomposes faster than grassland areas. Multiple regression suggests a negative association between soil temperatures and decomposition. On a local scale, the empirical relationships developed here are useful for a better understanding and modelling effects of climatic factors on litter decomposition rates

Forage Res 2021, 47(1), 105-12.
Field experiment was conducted during kharif season of 2019 at Department of Livestock Farm Complex, Veterinary College, Shivamogga. The experiment was laid out in a randomized complete block design with thirteen treatments having three replications. During the experiment, three hybrid napier cultivars, i.e., Dharwad Hybrid Napier-6, CO-5 and Taiwan Super Napier-1 & three fodder cowpea genotypes, i.e., Cowpea local, MFC-09-1 and MFC-08-14 were used. Fodder cowpea genotypes were tested as an intercrop in different hybrid napier cultivars under normal spacing and paired row. Combinations of hybrid napier cultivar Taiwan Super Napier-1 with fodder cowpea improved genotypes (MFC-08-14 and MFC-09-1) in paired row performed better and found significantly superior over cultivar Dharwad Hybrid Napier-6 with different genotypes of fodder cowpea. The combination registered higher plant height (373 cm), number of tillers/plant (73.67) and number of leaves/plant (434.67), green fodder yield (321.21 t/ha), dry fodder yield (66.09 t/ha) and per plant yield (17.35 kg). This was closely followed by hybrid napier cultivar CO-5 with fodder cowpea improved genotypes. Different genotypes of fodder cowpea did not differ in green and dry fodder yields but normal planting resulted maximum tonnage of green and dry fodder (7-8 and around 1.5 t/ha, respectively) compared to paired row system (5-6 and around 1.0 t/ha) due to difference in population.

Forage Res 2021, 47(1), 95-9.
A study was conducted during kharif season of 2020 on sandy loam soils of forage research farm of PAU, Ludhiana to study the interactive effects of different fertility levels {control, 50:10:12.5, 100:20:25 (recommended dose of fertilizers) and 150:30:37.5 kg N: P2O5 : K2O per ha} and five genotypes (SPV 2584, SPV 2587, SPV 2593, CSV 21F and CSV 30F) on growth, yield, quality and disease incidence of single cut forage sorghum. The experiment was laid out in Randomized Complete Block Design (RCBD), using three replications. It was revealed from the results that SPV 2584 owing to its profused tillering gave highest green fodder yield to the tune of 76.4 % over the check genotype CSV 30F. The genotypes SPV 2593 and CSV 21F remained statistically at par with SPV 2584 with regards to green fodder productivity. The genotype SPV 2584 also remained superior in terms of quality of green fodder recording highest value of crude protein content (6.36 %) and lowest value of hydrocyanic acid (44.7 %) over other genotypes. The effect of fertility levels was found to be significant upto 100:20:25 kg NPK/ha giving 21.6 and 26.6 % increase in green fodder and dry matter yield, respectively with 50 percent increase in fertility level. The quality of forage sorghum increased with increase in fertility level with corresponding increase in HCN also. The effect of fertility and genotypes on disease severity was found to be significant and highest disease reduction of anthracnose (35.1 %) was recorded with application of 100:20:25 kg NPK/ha.

Forage Res 2021, 47(1), 84-8.
Efficient sources of nutrients supplying the nutrients with greater efficacy and high yielding pearl millet hybrid with nutrient responsiveness plays an important role in yield enhancement and quality improvement on pearl millet in the arid region under sandy loam soil. To find out the influence of customized fertilizers and hybrids on growth and yield of pearl millet, field experiments were carried out during kharif seasons of 2019 and 2020 at ICAR-All India Coordinated Research Project on Pearl Millet, Research Farm, Agricultural Research Station, Mandor, Jodhpur (Agriculture University, Jodhpur). Customized fertilizer substantially enhanced growth attributes viz., plant height (200.8 and 183.5 cm), days to panicle initiation (23.0 and 22.7 days), days to 50 % flowering (46.8 and 44.7 days), days to maturity (86.7 and 83.8 days) during 2019 and 2020, respectively over control. Application of customized fertilizer recorded markedly higher grain yield (2124 and 1896 kg/ha) and straw yield (3611 and 3223 kg/ha) during 2019 and 2020 over control and straight fertilizer. Among hybrids, substantially taller plants were observed by the pearl millet hybrid ‘MPMH 17’ (192.6 cm) during 2019 and ‘RHB 173’ (171.6 cm) during 2020. The hybrid ‘RHB 173’ took a greater number of days to panicle initiation (23.8 and 23.7 days), days to 50 % flowering (49.1 and 48.0 days) and days to maturity (84.3 and 82.2 days) during 2019 and 2020. Economic analysis envisages, application of customized fertilizer fetched significantly higher gross return ( 60,528 and 56,872/ha), net return ( 34,072 and 36,307/ha) and B: C ratio (2.75 and 2.49) during 2019 and 2020 over control. Likewise, markedly higher gross return ( 60,109 and 55,638/ha), net return ( 40,361 and 35,061/ha) and B: C ratio (3.02 and 2.68) was obtained by hybrid, ‘MPMH 17’ during 2019 and 2020.

Present investigation was carried out during Rabi season of 2018-19 at Wheat Section Research Area of CCS Haryana Agricultural University, Hisar. The experiment was laid out in split plot design with four replications. In main plot, three cutting schedules i.e. 45 DAS, 55 DAS and 65 DAS were taken and six nitrogen schedules i.e. N1 - 1/3 basal +1/3 at first irrigation and 1/3 after cut, N2 - ½ basal + ½ at first irrigation, N3 -½ basal and ½ after cut, N4 - ¼ basal +½ at first irrigation and ¼ after cut, N5 - ½ basal +¼ at first irrigation and ¼ after cut, N6 - ¼ basal +¼ at first irrigation and ½ after cut as sub plot treatments. Based on the research findings, it was observed that different cutting and nitrogen schedules significantly influenced the growth, yield attributes and yield of dual-purpose wheat. Crop cut at 45 DAS for green fodder resulted in significantly higher plant height, dry matter accumulation (415.0 g), number of tillers (112.2 /mrl), number of effective tillers/mrl (102.87), grains per spike (47.61) and 1000 grain weight (42.57g) as compared to crop cut at 55 DAS and 65 DAS. Crop cut at 45 DAS for green fodder also produced maximum grain yield (61.36 q/ha) and straw yield (98.12 q/ha), which were significantly higher than cut at 55 and 65 DAS. Whereas, minimum grain yield (47.42 kg/ha) was recorded when crop cut was taken at 65 DAS for green fodder. Among different nitrogen schedule, N3 resulted in maximum plant height (106.9 cm), dry matter accumulation, number of tillers (109.0), number of effective tillers (100.50), grain per ear head and 1000-grain weight. Similarly, maximum grain yield (56.88 q/ha) was recorded when half nitrogen dose was applied as basal and half dose of nitrogen was applied just after cut (N3 ) which was significantly higher than N2 and N5 but it was at par with N1 , N4 and N6 . Whereas, minimum grain yield (54.09 q/ha) was recorded with N2 treatment. However, maximum straw yield (98.12 qha-1) was recorded with N1 being at par with N3 and N6 but significantly higher as compared with rest of the nitrogen schedule.

Forage Res 2021, 47(1), 73-8.
Salt stress has been considered a major limiting factor to crop productivity in arid and semiarid regions. The present study was conducted to evaluate the sorghum genotypes superior in quality and yield under saline conditions. The two factor experiment was carried out in a completely randomized block design with three replications during the kharif season 2018 and 2019. Crude protein content and IVDMD decreased significantly under different salinity levels. The higher reduction being reported in PC-5 than SSG 59-3. Crude protein yield (CPY) and digestible dry matter (DDM) was maximum in SSG 59-3 and minimum in PC-5 at 10 dSm-1. Salt stress showed an adverse effect on yield attributes and yield, so seed yield per plant, green fodder yield (GFY), and dry matter yield (DMY), decreased under salt stress. GFY and DMY were maximum in SSG 59-3 while minimum in PC-5. Better performance was maintained by SSG 59-3 than PC-5. This, SSG 59-3 (salt-tolerant) genotype acclimated better than PC-5 (salt-sensitive) genotype by maintaining the fodder quality and yield and may be exploited in plant breeding programs aimed at developing salt-tolerant sorghum genotypes for salinity prone areas.

The study involving twenty-eight genotypes of Anjan grass with two checks were evaluated in a Randomized Block Design with two replications at Grass Breeding Scheme, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar, Maharashtra. Treatment differences were found to be significant for all the characters studied. High estimates of GCV and PCV were observed for traits viz., number of tillers/plant, leaf breadth, spike length and number of spikes per plant. High estimates of heritability (b.s.%) accompanied by high estimates of genetic advance as percentage of mean were observed for the characters namely number of tillers/plant, number of leaves/tiller, leaf length, leaf breadth, spike length, number of spikes/plant, spikelets per spike and green fodder yield. The characters like plant height, number of tillers per plant, leaf length, leaf breadth, spike length, spike breadth, spikelets per spike and dry matter percent showed significant positive genotypic and phenotypic correlations with green fodder yield. Leaf length exhibited high positive direct effect and significant positive genotypic correlation with green forage yield followed by leaf breadth, plant height, number of tillers per plant and spike breadth. The characters spike length, spikelets per spike and dry matter also exhibited high negative direct effects on green fodder yield, however its association with green fodder yield observed to be strong and positive. Thus indicating that emphasis should be given on these characters for green forage improvement in Anjan grass.

The present investigation was undertaken at Upland Research cum Instructional Farm, Lamker, SGCARS, IGKV, Raipur in Kharif 2018-19 with 100 germplasm accessions to evaluate the forage potential of finger millet (Eleusine coracana L.) in augmented randomized block design. Mean squares for analysis of variance indicated significant differences among blocks, check and test entries for crop duration, canopy length and fodder weight. The maximum canopy length was recorded in genotype GEC-5 (126cm) followed by GEC-186 (125 cm), GEC-92 (124 cm), GEC-310 (122 cm), GEC-314 (120 cm) and others. Referring to crop duration, genotype IC0476378, IC0477043, GEC322, GEC-11, IC0477620, GEC-296, GEC-53 and GEC-352 can be considered as good for medium fertile soil and average monsoon regions in lieu of mid-durational maturity. For fodder yield, IC0476495 (1646 g/plot) was recorded as most dominating genotype referring to the breeding objective and subsequently GEC11 (1222 g), GEC92 (1112 g), IC0477620 (1042 g), GEC132 (1027 g) and IC0477556- X (990 g) also showed fair potential. To get establish general crop growth parameters in association with fodder as objective, we conclude that 95-105cm of canopy length and 105-115 DAS of crop may be opted to achieve the maximum forage potential in finger millet. We further suggest that IC0476495, GEC11, GEC92, IC0477620, GEC132, IC0477556-X, IC0476838, IC0477317, GEC274, IC0477560, IC0477591 and GEC135 shown good potential and should be revalidated in next crop season followed by incorporation in replicated trials.

Forage Res 2021, 47(1), 19-28.
Pearl millet is a major cereal crop in northwestern India. It is the most drought-tolerant cereal grown in the arid and semi-arid regions. Its grains are valued as human food while its fodder makes important livestock ration in crop–livestock farming system. The production potential of rainfed pearl millet is continued to be low as a result of frequent drought due to high variability in rainfall (amount and distribution) during the growing season, low soil fertility, low plant nutrient use, and poor socio-economic conditions of farmers, could not use high technology input. This review mainly highlighted various improved practices for increasing productivity and profitability of fodder and grain type pearl millet. It includes soil moisture conservation practices by practicing the improved planting methods, supplemental irrigation, use of improved varieties, and intercropping. Integrated use of fertilizer and use of low energy input for enhancing the crop productivity.

Maize (Zea Mays) plant is affected by number of foliar diseases among of them, Southern Corn Leaf Blight (SCLB) or Maydis Leaf Blight (MLB) incited by the Helminthosporium maydis anamorph: Bipolaris maydis, telomorph: Cochliobolus heterostrophus is one of the most devastating disease of maize in India as well as in the world. Three different races namely race O, T and C of helminthosporium are found responsible for causing this disease. Bipolaris has the potential to reduce the yield significantly up to 70 % depending upon the susceptibility, race of pathogen and environmental conditions.Genetic architecture of maize possess the diverse source of resistance against Helminthosporium which are qualitative, quantitative and multiple disease resistance types in nature but often represents quantitative nature of resistance. A single gene, rhm, imparts a qualitative-like resistance against race O which inherits recessively with additive gene action predominantly. It is implied at the seedling stage but quantitative resistance is needed after silking stage. An additional two resistance genes have been identified in the inbred NC250 that are not allelic to rhm and this resistance is maintained in mature plants. Plenty of attempts have been made to identify the resistance source and to dissect the quantitative trait loci (QTL) responsible for resistance or multiple disease resistance to SLB across different maize populations. QTLs responsible for multiple disease resistance were identified of elucidated with the help of meta analysis of available studies.

Conventional tillage practices lead to change in soil structure by modifying soil bulk density and soil moisture content. Continuous disturbance of soil by conventional tillage makes finer and loose-setting soil structure while conservation and no-tillage methods leave the soil intact which results in a change of characteristics of the pores network. Losses of soil organic C (SOC) and deterioration in other properties exaggerated where conventional tillage was employed whereas conservation tillage improved soil quality. When conventional tillage is replaced by conservation tillage CO2 emissions from soil is reduced. Conservation tillage is thought to take care of the soil health, plant growth and the environment. Forage crop production could be increased by adopting appropriate tillage operation. Conservation tillage has potential to break the surface compact zone in soil with reduced soil disturbance which leads to a better soil environment and crop yield with minimal impact on the environment and sustainable crop production. Macro- and micronutrients, fiber and protein contents are changed in silage by means of different tillage practices. Generally, conservation tillage has profound effects on forage yield. Zero tillage with mulch, zero tillage without mulch, ploughing, and ploughing plus harrowing had more yield than ploughing plus harrowing twice by 33.7, 30.5, 18.9 and 17.9 %, respectively. Conservation tillage lead to lower methane emission in comparison to conventional tillage; on average, 0.32 kg CH4 -C ha-1 year-1 was oxidized with conservation tillage. Capacity building on innovative conservation tillage practices is crucial for researchers, extension workers, development practitioners and the smallholder farmers.

Field experiments were conducted at Agriculture Farm, A.R.S., Navgaon, Alwar during two consecutive seasons viz., Kharif 2019 and Rabi 2019-20 to evaluate the effect of biochar and fertilizer’s on cluster bean and it’s residual effect on wheat. The experiment was laid out in randomized block design with 7 treatments and three replications. The results revealed that the application of 100 % RDF + 15q biochar in cluster bean recorded highest in all growth and yield parameters in both crops. In cluster bean, the maximum grain (14.72 q/ha) and straw yield (36.31 q/ha) were recorded under the treatment 100 % RDF + 15q biochar, which were 17.26 & 11.67 % higher over 100 % NPK alone in grain and straw yield, respectively. The residual effect of treatments also observed significant in wheat, the maximum grain (42.60 q/ha) and straw (63.80 q/ha) were recorded where 100 % RDF + 15q biochar treatment applied in previous crop, which were 10.46 & 10.13% higher over 100% NPK alone in grain and straw yield, respectively. On the other hand the lowest values of grain and straw yield were obtained from control treatment. Similar trend was also recorded in plant height, 1000 grain weight in both crops. Similarly, the direct and residual effect of biochar on N,P,K content in grains and straw as well as total uptake were also recorded higher with the application of 100 % RDF + 15q biochar in cluster bean.

Forage Res 2021, 46(4), 368-73.
In the present investigation, four berseem varieties viz., Wardan, BB2, BB3 and JBSC-1 were tested for their relative salt tolerance to increasing levels of salinity in the combinations of salts which nearly exist in the natural salt affected soils in India. Seeds were germinated in petri dishes and were exposed to four salinity [(4,8,12 and 16EC (dS m-1)] levels. The germination percentage, shoots and root length, fresh and dry weight of seedling were recorded. The results revealed that the effect of salt levels on these parameters was significant (p< .05). Higher loss of germination percentage was found in BB2 at different levels of salinity than in JBSC-1. It was inferred that salinity stress significantly decreased germination and growth parameters of seedlings of four berseem varieties; however, varieties JBSC-1 and Wardan were found relatively tolerant to salinity than BB2.

Nitrogen and phosphorus are the nutrient that most frequently limits yield and plays an important role in quality of forage crops. To investigate the effect of varying nitrogen and phosphorus levels on growth, yield and quality of spring fodder maize (Zea mays L.), a field study was conducted during spring 2019 at Agronomy Research Farm, CCS Haryana Agricultural University, Hisar located at 29 °16’N latitude and 75 °7’E longitude at an elevation of 215.2 m above the mean sea level in northwest part of India. The soil of the experimental field was sandy loam in texture, neutral in reaction, low in organic carbon and available nitrogen, medium in available phosphorus and high in available potassium. The experiment was laid out in FRBD design with four nitrogen levels (0, 50, 75 and 100 kg N/ha) and four phosphorus levels (0, 15, 30 and 45 kg P2O5 /ha) replicated thrice. Overall results depicted that growth parameters, yield attributes and yield of fodder maize in spring season increased with the increase in nitrogen and phosphorus levels upto 100 kg N/ha and 45 kg P2O5 /ha, respectively. With the application of nitrogen @ 50, 75 and 100 kg N/ha there was 27.86, 49.50 and 64.50 per cent increase, respectively, in green fodder yield over the control (no nitrogen). Application of increasing level of nitrogen and phosphorus increased the soil available nitrogen and phosphorus status over control. Application of 100 kg N ha-1 and 45 kg P2O5 /ha recorded highest crude protein (%) and crude protein yield of fodder maize, however, the crude protein recorded at 50, 75 and 100 kg N/ha was statistically at par with each other. Synergistic effect of N and P was observed on green fodder and dry matter yield.

To improve quality and digestibility of maize stover for meeting the nutritional requirements of livestock, it was subjected to different pre-treatments. Treatment of maize stover with sodium chloride (2 %) resulted improvement in CP content (18.43 %) and in vitro dry matter digestibility (16.80 %). The decrease in ADF (7.35 %) and cellulose content (3.40 %) was also observed after the treatment. Pre-treatment of stover with calcium hydroxide revealed increase in total carbohydrate and ash content of stover. The calcium hydroxide treatment was also effective in lowering the NDF (8.80 %) and ADL content (55.30 %) of stover. Treatment with ammonia resulted significant reduction in silica (52.63 %), total phenolic (67.70 %), simple phenolic (66.90 %) and total tannins content (68.60 %). Maize stover inoculated with Pseudomonas fluorescens revealed increase in CP content (49.10 %) and decrease in ADF (5.40 %), cellulose (1.60 %) and simple phenolic (59.40 %) contents. Treatment with Trichoderma viride resulted 27.70 % increase in total carbohydrate content of stover. Highest reduction in silica content (47.40 %) was recorded with Saccharomyces cerevisae treatment. Inoculation of Trichoderma harzianum lowered the NDF (5.79 %), hemicellulose (16.50 %), total phenols (34.40 %) and total tannins (18.90 %) content of stover. This treatment was also effective in improving stover digestibility up to 17.84 %. The study indicated that treatment of maize stover either with alkali or inoculation with Pseudomonas fluorescens and Trichoderma harzianum are effective for improving nutritional quality of maize stover.

The study was conducted to assess seed priming effect on enzyme activities of five maize hybrids of Public and Private seeds sectors viz., PMH-1, IIMRNH 2015-3, IIMRNH 2015-4, P3396 and DKC 9144 during 2018-19 at laboratories of Department of Seed Science & Technology, CCS, Haryana Agricultural University, Hisar. The seeds were primed with KH2 PO4 (2.0 %), KNO3 (1.0 %), GA3 (50 ppm) and hydration with water followed by dressing with vitavax power @ 2.5g/kg seed for 17 hours at room temperature and then dried to original moisture content for 24 hours at 40 °C temperature. The results revealed that all priming treatments for 17 hours reduced Dehydrogenase, Catalase, Superoxide dismutase, Peroxidase activities which indicates negative effect on seed quality of maize hybrids. Hence, priming method for maize hybrids need to be standardized. Priming with KH2 PO4 (2.0 %) and KNO3 (1.0 %) was found most effective where improvement was more over other treatments. Maximum Dehydrogenase (0.173) and Superoxide dismutase (0.623) activity was recorded in unprimed seeds while maximum Catalase activity (0.417) was recorded in seeds primed with KH2 PO4 (2.0 %) and maximum Peroxidase activities (2.574) was recorded in seeds hydrated in tap water. Among the hybrids, DKC 9144 recorded superiority over other hybrids by registering maximum enzymic activities viz., Dehydrogenase activity (0.210), Superoxide dismutase (0.717), Peroxidase (0.2791) and minimum electrical conductivity (87.8), so this hybrid can be used in further breeding programmes.

The present study was conducted with 25 exotic germplasm accessions along with three checks at Forage Research Farm, Department of Plant Breeding and Genetics, Punjab Agricultural University, Ludhiana during Rabi season 2019-2020. The objective of the study was to determine the extent of correlation among green fodder yield with contributing traits and their effects. The high value of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) was observed for number of leaves followed by green fodder yield and number of tillers. High heritability was estimated for percent crude protein content (99.68 %), number of leaves (97.84 %) and acid detergent fiber (97.09 %). Higher genetic advance was observed for number of leaves (98.70 %) and green fodder yield (79.38 %). Traits like plant height (0.533), leaf length (0.416) and leaf width (0.292) had positive and significant correlation with green fodder yield. Positive and direct effect of plant height (0.942) and number of leaves (0.218) on green fodder yield. The results suggest that traits like plant height, leaf length and leaf width are the main fodder yield components. So, selection for these traits should be practised in future breeding programme for improving the green fodder yield in oats.

In order to elucidate the per se performance and selection strategies for development of high yielding varieties and/ or promising genotypes under organic condition, 12 varieties of barley were grown and evaluated for 10 metric traits during rabi 2015-16 at Experimental Area of Wheat and Barley Section of Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar. The analysis of variance indicated high significance of mean sum of squares due to treatments for all the traits studied. Three varieties viz., BH 946, BH 902 and DWRB 101 produced higher grain yield and also showed better performance for several other yield components. These genotypes can be used in barley improvement programme and will be helpful in breaking the yield plateau under organic field condition. Moderate to high heritability coupled with high genetic advance was revealed by grains per spike, grain yield per plot, peduncle length, spike length and plant height. Correlation analysis indicated highest significant positive correlation of grain yield per plot with biological yield per plot, followed by harvest index and days to maturity at both genotypic and phenotypic levels. Among all the traits, biological yield per plot, harvest index, spike length and peduncle length reflected positive direct effect on grain yield per plot. Therefore, to obtain high yield, one should consider these traits in barley breeding programme.

Forage Res 2021, 46(4), 320-4.
The present investigation was carried out to study gene action and combining ability in sorghum [Sorghum bicolor (L.) Moench]. The experimental material consisted of six parents (including check GJ 43 and CSV 32F (forage)) and their 15 half-diallel crosses. The seeds of 15 F1 hybrids were produced during summer 2019 at Sorghum Research Station, S. D. Agricultural University, Deesa, by manual emasculation and crossing. The seeds of parental lines were maintained through selfing. The analysis of variance for combining ability results revealed that mean sum of squares due to general combining ability were found highly significant for all the traits except the number of leaves per plant. In comparison, the specific combining ability effects were found significant for all the traits. Parents’ gca effects explicated that the parents CSV 21F and UTFS 91 were perfect general combiner for both green fodder yield per plant and dry fodder yield per plant. The patent Malwan found perfect general combiner for plant height (cm), leaf: stem ratio and Brix value. The parent GFS 4 perfect general combiner for days to flowering, days to maturity and protein content. A perusal of data of sca effects implied that the cross combinations GFS 4 × UTFS 9, Malwan × GJ 43 and PSVGS 313 × UTFS 91 recorded the highest sca effects, which were also highest in per se performance which involved poor × good, poor × average, average × good parents combination, respectively.

The 40 accessions of pearl millet were evaluated in randomized block design with three replications at experimental farm, SKN College of Agriculture, Jobner (Rajasthan) during Kharif 2019. The wide range of genetic distinction for yield and yield component traits was recorded in the germplasm considered under study. The first four principal components having eigen value greater than one were extracted from the mean of 10 traits in 40 accessions with 67.61% variances. A variance of 25.71, 16.87, 13.32 and 11.69 % were extracted from first, second, third and fourth principal components, respectively. Hierarchical clustering technique based on ten quantitative trait data using Ward’s method grouped 40 genotypes into five clusters with clear differentiation for different quantitative traits. Mostly accessions were not assembled into the same cluster based on their geographical origins. Based on PCA analysis, the first principal component (PC1) was the most important which accounted 25.71 % of variation with the major contributors traits biological yield per plant, plant height, panicle length, grain yield per plant and 1000-grain weight. Based on cluster analysis, genotypes of different origin like RIB-12141, Jhukarana, H-77/833-2, G-73-107, RIB-9215, RIB-16332, Desi panchu, AICRP(PM)-21, RIB-10011, AICRP(PM)-292 were grouped in cluster I therefore, breeders can use these genotypes directly as inbred lines and also for further hybridization with low yielding clusters like cluster II and V for yield improvement in pearl millet.

Knowledge about the relationship between green and dry biomass yield, grain yield, and quality traits is important for any dual-purpose sorghum development program. Thus, the objective of this study was to determine correlations and path-coefficients between green fodder yield, stover yield, grain yield and quality traits. The field experiment was conducted at Research Area of Forage Section, Department of Genetics and Plant Breeding, CCS HAU, Hisar during kharif 2019 by using 30 genotypes to study the variability, heritability, genetic advance and genotypic and phenotypic correlations on the basis of nineteen agro-morphological and biochemical parameters. Analysis of variance showed highly significant variation for 19 quantitative parameters under study. Significant variation among all the genotypes was recorded for all the characters. High heritability coupled with high genetic advance was reported for green fodder yield, stover yield and protein yield. In correlation studies, it was observed that green fodder yield was found positively associated with plant height, leaf length, leaf breadth, stem diameter, stover yield, dry fodder yield, grain yield, panicle length, 100 grain weight, protein content and protein yield. HCN content was negatively correlated with green fodder yield and dry fodder yield. In path coefficient analysis, green fodder yield (0.4165), grain yield (0.7330), stover yield (0.6543), plant height (0.6983), TSS content (0.3873) had high positive direct effect on dry fodder yield. However, traits like panicle length (-1.0237), no. of tillers/plant (-0.5931), leaf breadth (-0.4657) and stem diameter (-0.4657) had shown negative direct effect on DFY.

Climate change is a growing concern and its impacts are reflected in almost every sector and is mainly due to the increase in greenhouse gases. There is a leap in atmospheric concentration of carbon dioxide has observed from 1930 (278 ppm) to 2018 (408 ppm) and it expected to cross 1000 ppm at the end of the century (IPCC, 2019), which is a major warning to food-fodder security and climate change in 21st century. Fodder production systems play a major role in mitigating climate change through improving carbon sequestration, reducing methane emission per unit livestock product and reducing nitrous oxide emission. Grasslands, pastures and forage crops contribute greatly in the global carbon cycle which stocks at least 30 per cent of world soil carbon. Many strategies can be adopted to enhance the carbon sequestration in fodder production system like implementation of pasture based agro forestry practices, restoration of degraded lands and inclusion of grasses and grazing management. Supplementation of suitable fodder in diet with high digestibility and high energy and protein concentrations will reduce the total methane emission per unit livestock. Certain pastures has a capacity to release biological nitrification inhibitors from their roots, which suppress nitrifier activity and reduce soil nitrification and nitrous oxide. Thus there is a need for strategies that will enable reduced GHG emissions through sustainable intensification of forage production systems to enhance productivity, income generation, climate mitigation and ensuring food-fodder security.

001010 VIVEKANANDAN N (Central Water and Power Research Station, Maharashtra) : Intercomparison of estimators of extreme value family of distributions for rainfall frequency analysis. Water Energy Int 2021, 64r(2), 24-32.
Estimation of rainfall for a given return period is of utmost importance for planning and design of minor and major hydraulic structures. This can be achieved through Extreme Value Analysis (EVA) of rainfall by fitting Extreme Value family of Distributions (EVD) such as Generalized Extreme Value, Extreme Value Type-1, Extreme Value Type-2, and Generalized Pareto to the series of observed Annual 1-Day Maximum Rainfall (AMR) data. Based on the intended applications and the variate under consideration, Method of Moments (MoM), Maximum Likelihood Method (MLM) and L-Moments (LMO) are used for determination of parameters of probability distributions. The adequacy of fitting EVD to the AMR series is evaluated by quantitative assessment using Goodness-of-Fit (viz., Chi-square and Kolmogorov-Smirnov) and diagnostic test (viz., D-index) tests and qualitative assessment using the fitted curves of the estimated rainfall. The paper presents a study on intercomparison of EVD (using MoM, MLM and LMO) adopted in EVA of rainfall with illustrative example and the results obtained thereof.
