SUMMARY

Land fragmentation and industrialization pulling back the agricultural output and have a tremendous pressure on nation’s food security. Oat is an emerging dual crop which provides high quality grains for human consumption and nutritious fodder for cattle feeding. To feed the world’s largest cattle population, it is the present duty to increase productivity of oat with agronomic optimization in pre-exist cultivars. Optimization of nutrient management is always a daunting task among the agronomic practices because it is a complex phenomenon to estimate the nutrient balance to get efficient fertilization promising sustainability of the system. Biofertilizers, which are the living cell inoculums fixing atmospheric N and solubilize fixed P, K and other micronutrients can be a great option when applied judiciously with other nutrient sources to achieve the goal. Therefore, there is a need for an efficient nutrient management for sustainable oat production.

SUMMARY

Endophytes are the microorganisms that live inside different plant tissues for a part of their life without harming their host plant species. Beneficial endophytes facilitates plant growth by enhancing the uptake of plant nutrients, protecting plants from plant pathogens and increasing plants tolerance against various abiotic stresses. Endophytes combat with phytopathogens using different mechanisms viz., siderophore production, HCN, antibiotic production etc. Considering the beneficial effects of endophytes, their use in sustainable agricultural practices will play a pivotal role and offer ecofriendly strategy for enhancing the productivity of forage and other crops while decreasing the use of chemical pesticides in plant disease management

SUMMARY

A field experiment was conducted at the Instructional cum Research farm of Assam Agricultural University, Jorhat (Assam) during Rabi 2017-18 to evaluate genotypes for high forage yield coupled with low ODAP content. Seven diverse parental lines of grass pea were crossed in a 7×7 diallel mating design excluding reciprocals. The twenty one F1 hybrids obtained were evaluated along with their parents in a Randomised Block Deign with 3 replications. Analysis of variance revealed significant differences among the parents and the F1’s for all the characters studied. The studies on combining ability indicated the predominance of dominance variance for most of the characters studied except for days to 50% flowering and leaves per plant. The parent Prateek was the best general combiner for both green forage yield per plant and for low ODAP content. Based on SCA effect and per se performance the cross Nirmal × Prateek was the best specific combiner for green forage yield, while the cross Prateek × JCL-3 was the best specific combiner for low ODAP content. Significant heterosis was observed in desirable direction for most of the traits. From the estimation of heterosis over mid parent and better parent, the cross JCL-2 × JCL-3 was the best heterotic cross for green forage yield per plant while the crosses Prateek × JCL-3 was recognized as best heterotic cross for ODAP content.

SUMMARY

A total of twenty five genotypes were characterized according to twenty morphological and seed traits. The genotypes differed significantly for most of the traits and relatively wide range of mean for all traits indicated the presence of variation among the tested genotypes. High phenotypic and genotypic coefficient of variation, high heritability coupled with genetic advance as percent of mean based on pooled analysis revealed for seedling dry weight per plant and seed vigour index. Seed yield per plant was showed positive and significant correlation with harvest index, biological yield per plant, dry weight per plant, number of reproductive tillers per plant leaf width, test weight, plant height and number of seeds per main spike, while negative significant with days to flowering and days to maturity at both phenotypic and genotypic levels. High positive direct contribution of biological yield per plant followed by number of leaves per plant, seed germination, spike length, leaf length, harvest index, biomass yield per plant, days to flowering seedling dry weight per plant and number of reproductive tillers per plant simple selection could be effective for these traits. The Cluster with higher number of lines means had low genetic diversity and they are more closely related. Highest intra cluster distance was observed for cluster I and maximum inter cluster distance was observed between cluster I and III indicates that the genotypes included in these clusters are having broad spectrum of genetic diversity and could very well be used in hybridization programme of oat for improving seed yield. Whereas the minimum average inter cluster D2 value was recorded between cluster III and II. The lowest inter cluster distances indicate that the genotype of these clusters had close relationship and hence, may not be emphasized upon to be used in hybridization programme. The genotypes viz; JHO 03-91, SKO 105, CSAOFSC 14-6, SKO 101, JHO 2007-1, NDO 612 and JHO 851 and cluster III characterized by days to maturity, leaf width, number of nodes per plant number of leaves per plant, biological yield per plant, dry weight per plant and spike length with genotypes namely; CSAOFSC 11-5, CSAOFSC 11-1, CSAOFSC 12-1, UPO 212, CSAOSC 12-1 and OS 403 were expected to exhibited high heterotic performance and are also likely to produce new recombinants with desired characters to get desirable segregates with higher seed yield for developing superior variety of oat.

The experiment in sorghum [Sorghum bicolor (L.) Moench] was carried to study gene action and combining ability of 27 hybrids were generated by L × T fashion during early summer, 2018 at Sorghum Research Station, SDAU, Deesa. The 27 hybrids along with 12 parents and two standard checks (GJ 39 and CSH 30) were evaluated in randomized block design with three replications at Sorghum Research Station, SDAU, Deesa (Gujarat) during kharif, 2018. The ratio of σ2gca2sca being more than unity was found for days to flowering, stem girth and leaf width which suggested greater role of additive genetic variance in the inheritance of these traits. Based on the gca effect, the parents DS 173, DS 156 and DS 155 were good general combiners for green fodder yield per plant and the parent DS 137, DS 149 and DS 155 were found good general combiners for grain yield per plant.. The hybrids 7A × DS 161, 296A × DS 137 and 7A × DS 149 for grain yield per plant and 296A × DS 161, 7A × DS 156 and 2219A × DS 155 for green fodder yield per plant were the most promising hybrids on the basis of significant positive sca effect. These crosses also exhibited positive significant sca effect for other contributing traits viz., plant height, leaf length, leaf: stem ratio, dry fodder yield per plant and protein content. Thus these hybrid showing significant sca effect can directly used for hybrid breeding programme.

SUMMARY

A field experiment was conducted at two different areas of the Instructional-Cum-Research (ICR) farm of the Assam Agricultural University, Jorhat in 2014-15 and 2015-16 to study the “Productivity of food-forage intercropping system as influenced by integrated nutrient management”. The treatments consist of four intercropping system viz. C1: sole oats, C2: sole pea, C3: 3:2 row proportions and C4: 3:3 row proportion of oat+pea intercropping and four integrated nutrient management Viz., F1: RDF (inorganics), F2: 50% N of RDF + 50% N through FYM, F3: 50 % N of RDF + 50% N through vermicompost and F4: 50% N through FYM + 50% N through vermicompost. Thus sixteen treatment combinations were laid out in split plot design with three replications with intercropping system in the main plots and INM in the sub-plots. The soils of the experimental site were acidic in reaction, sandy loam in texture, medium in OC, low in available N and P2O5 and medium in K2O. Highest green forage and dry matter yield was recorded in sole oats, among the intercropping system the highest green forage yield of 199.38 and 217.98 q/ha and dry matter yield of 43.52 and 49.72 q/ha was recorded in 3:2 row proportions during 2014-15 and 2015-16 respectively. Application of 50% N of RDF + 50% N through vermicompost to oats gave the highest green forage and dry matter yield during 2014-15 and 2015-16. Superior pod yield was recorded in sole pea culture showing the value of 44.74 and 47.24 q/ha in 2014-15 and 2015-16 respectively. The pea equivalent yield was observed to be highest in sole pea but among the intercropping system statistically superior pea equivalent yield was recorded in 3:3 row proportions over 3:2 row proportions and sole oats in both the experimental years. Integrated nutrient management on pod yield, green forage yield, dry matter yield and pea equivalent yield was significantly higher in 50 % N of RDF + 50% N through vermicompost than the other treatment combination in both the years. Therefore, in oat-pea intercropping system, it can be recommended to apply 50% RDF through vermicompost + 50% RDF through inorganic fertilizers, which will reduce the load of chemical fertilizers up to 50% with 3:3 row proportions of oat+pea intercropping systems.

SUMMARY

Poor germination and inconsistent plant population of the crop is due to the delay in sowing and reduction in the moisture content of the soil. Seed priming is the process of controlled hydration of seeds at a level that gives permission to pre-germination metabolic activity to proceed but prevents actual emergence of the radical. A study was conducted to find out the best seed priming method to enhance the fodder yield of maize African tall. Among the various treatment combinations of seed priming, significantly higher germination percentage at 88.88%, green fodder yield, dry matter yield and crude protein yield of 756.98, 159.89 and 13.32 q/ha respectively were recorded in treatment of maize African tall seed with ZnSO4 @ 0.5% for 12 hrs which was at par with seed priming with ZnSO4 @ 0.5% for 6 hrs. The maximum net monetary return was obtained in seed priming treatment of with ZnSO4 @ 0.5% for 12 hrs with Rs 108225/ha followed by seed priming treatment of ZnSO4@ 0.5% for 6 hrs with Rs 105406/ha. A similar trend was observed in the benefit cost ratio.

SUMMARY

In India sorghum is the fifth most important cereal crop after wheat, rice, maize and barley. It is mainly grown in the region of Peninsular and Central India. Maharashtra is leading state in sorghum production followed by Karnataka while Andhra Pradesh, Madhya Pradesh, Gujarat, Rajasthan, Uttar Pradesh, Tamil Nadu and other states grow sorghum in small areas mainly for fodder. In Haryana, sorghum is grown as fodder crop and area of sorghum in Haryana is 40.3 thousand hectare, and total production of sorghum is 21.3 thousand tones with average yield of 528 kg per hectare (DOA, Haryana). The objective of the study was to find out the adoption level of modern sorghum production technology in Haryana on various parameters. In Gurugram district, two blocks were selected and out of these two blocks, eight villages were selected randomly for the study (Four villages from each block). 120 sorghum growers were selected from these eight villages and interviewed with the help of a well structured interview schedule on different independent and dependent variables. The collected data was analyzed with various statistical tools. The results of the study revealed that in case of recommended cultivars majority of respondents belong to full adoption category. Majority of respondents had partial level of adoption in recommended seed rate, time of planting, manure and fertilizers, intercultural operations, irrigation and disease and their control. To overcome the partial adoption, there are some strategies we should follow, like need to highlight the sorghum production to bridge the gap in demand and availability of fodder in the area. Regular trainings of sorghum growers should be organized related to fodder and animal sciences. Agriculture Officers must be given trainings through various refresher courses on sorghum and other fodder production technologies.
