Background: Pulses are rich in their nutritional values, but having lower yield as compared to cereals. For increasing yield parameters, various crop improvement programmes were used, which mainly depends on the genetic architecture of the crop and the type of gene action helps in deciding the breeding strategies. Keeping under consideration, the present study therefore, is important.Methods: Eighty one triple test cross progenies developed by crossing 27 lines with three testers viz., HPBU-111, Him Mash-1 and their F1s cross between (HPBU-111 x Him Mash-1). F1 seeds were produced by cross between HPBU-111 x Him Mash-1 during Kharif 2015. By crossing these three testers with 27 lines (females), 81 hybrids were developed during Kharif 2016. The eighty one F1 hybrids along with 27 lines and 3 testers were sown during Kharif 2017 in a randomized block design with three replications.Result: Epistasis was found to be an integral part of genetic variations for the traits viz., days to 50% flowering, days to 75% maturity, plant height (cm), number of branches per plant, pod length (cm), number of pods per plant, number of seeds per pod, seed yield per plant (g), biological yield per plant (g), 100 seed weight, harvest index (%) and protein content (%). i type epistatic interactions (additive x additive) had significant effects for all the traits except, plant height (cm), pod length (cm), number of seeds per pod and protein content (%). In addition to i (additive x additive), j+l (additive x dominance + dominance x dominance) type epistatic interactions was observed for all of the traits. Both additive and non-additive gene actions are important for most of the traits studied hence, simple selection procedures in the immediate progenies will not be so effective for achieving improvement in these traits.

The research was carried out in Dolog Masagal Subdistrict, Simalungun Regency, altitude ± 1.100 m above sea level. The research was conducted from January to May 2019. The purpose of this study was to determine the tolerance level of several hybrid corn varieties to cob rot disease. Methods for conducting the research used randomized block design (RBD) with 1 factor. Types of hybrid corn varieties tested were: Pioneer 29 (V1), NK 99 (V2), Pioneer 12 (V3), NK 22 (V4), Pioneer 4 (V5), Nusantara I (V6), Asia 1 (V7).The parameters observed were: plant height, cob diameter, cob length containing seeds, number of seed rows per cob, number of seeds per row, number of seeds per cob,  husk cover in cob, cob rot intensity, the amount of dry production per plot, and the weight of 1.000 seeds. Based on the research results, different types of hybrid corn varieties produce different tolerances of cob rot resistance in the Simalungun highlands. The most tolerant variety of cob rot disease is Pioneer 29 (mild damage scale = 0 - 10%). Different types of varieties planted also affect various components of growth and production, among others: plant height, number of seeds per row, number of seed rows per cob, husk cover on cob, dry production per plot, and weight of 100 grains. As for the parameters of cob diameter, cob length containing seeds and the number of seed rows per cob, the difference in varieties did not significantly affect.

SUMMARYEighteen varieties of safflower were studied in a randomized block design with five replications. Data on fourteen quantitative characters were recorded. Appreciable variability was displayed by all characters, especially yield and number of heads/plant. The heritability estimates ranged between 65 and 98%.Seed (achene) yield gave a significant positive genotypic correlation with number of seeds/head, head width, bract width and oil content. The 100-seed weight was significantly negatively correlated with the number of seeds/head and plant height at maturity. The genotypic correlations between yield/plant and four other traits were partitioned into direct and indirect effects. The highest direct positive contribution to yield was given by plant height, which had also a positive indirect effect via number of heads. The direct effect of the number of heads/plant was negative and the indirect effect via head width was positive.

The Field experiment was conducted to evaluate the effect of fertility management on growth, yield attributes and yield of pearlmillet in a Randomized Block Design (RBD) with ten treatments and four replications during summer, 2019 at Anand, Gujarat. The experiment comprises of different nutrient management practices including 100% and 75% RDF with 15 t and 10 t FYM along with Bio NP consortia. A significant higher growth and yield parameters enhancement with the application of 100% RDF + 15 t FYM ha-1 + Bio NP Consortia was recorded in plant height, number of tillers, length of ear head, protein content and biological yield. The treatment T5 produced maximum (91.5 q ha-1) biological yield and statistically it was on par with T9 and T5. However, the lowest biomass production (73.0 q ha-1) was reported in treatment T1. Results of different nutrient management practices on days to 50% flowering, days to maturity, ear head girth and test weight were found non-significant.  Protein content of pearlmillet was increased from 7.5% to 9.06% under different nutrient management practices.

Main Effect

Present study was carried out to screen the cowpea genotypes and to determine the effect of different level of aluminium on morpho-physiological, growth, yield and quality attributes. Twenty cowpea genotypes with four aluminium levels i.e. 0, 20, 40, 60 ppm in three replications was investigated in factorial complete randomized block design. Individual main effect and their interaction effects were studied for plant height at weekly interval, biomass, number of nodule per plant, root length, shoot length, dry matter of root, shoot, leaf, total dry matter, number of pod per plant, pod weight, yield and seed protein content. Cowpea genotypes exhibited significant differences for all 13 observed traits. Aluminium treatment expressed significant differences for all the attributes under study except biomass per plant. However, interaction effect was found to be significant for all studied characters except plant height at all stages. Among the aluminium treatments; observed traits were performing better at 20 ppm of Al, whereas, pod yield and protein content were best under the control.

This research was carried out in the Experimental Field of Tekirda đ Agricultural Faculty. Two common vetch varieties and 5 lines were sown with 150 seeds/m 2 plant density according to a randomised block design. Some important yield related characters such as plant height, number of branches, number of pods per plant, number of seeds per pod, pod width, pod length, 1000 seed weight, fodder and seed yield were examined. The results of variance analysis showed that the effects of genotype, year and their interaction on number of branches and number of pods per plant were all significant. In addition, the effect of year and variety on plant height and seed yield were found to be significant. Moreover, the number of seeds per pod, pod width and pod length were found to be significant in variety and year × variety interaction. There was only a difference between years for 1000 seed weight and fodder yield. According to the results, genotype 283 and Tokat had similar performance to that of commercial cultivars (Ürem, Kubilay). Especially the fodder and seed yield of genotype 283 were found to be higher than those of the cultivars (Ürem, Kubilay).

The present study was conducted to investigate the changes in yield attributes and protein content with the application of zinc and biofertilizers in hybrid rice and chickpea. The experiment was conducted in as a Randomized Block Design (RBD) in Students Instructional Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh, India, during 2018-2019 and 2019-2020. The experiment included twelve treatment groups replicated three times in Randomized Block Design. The results revealed that the treatment which received T7 (100 per cent RDN + 25 per cent N FYM + S40 + ZnO + *Azotobacter or **Rhizobium) recorded highest value of all yield attributes and protein content. The mean values of both years of plant height, number of tillers/hill, panicle length, no. of filled grains/panicle, no. of unfilled grains/panicle and total no. of grains/panicle increased up to 96.08 cm, 8.38, 24.29, 181.03, 18.71 and 199.74, respectively in treatment T7 in hybrid rice. Similarly, in case of chickpea the mean values of plant height, no. of branches/hill, no. of pods/plant, no. of seeds/plant, no. of nodules/plant and dry weight of nodules/plant also increased up to 62.60 cm, 5.22, 62.62, 1.88, 17.63 and 2.08, respectively. The protein content was also found to be maximum in Treatment T7 in rice (7.94 and 8.04%) and in chickpea (23.25 and 23.27%) during the years, respectively. Therefore, combination of micronutrients and biofertilizers, as remunerative and beneficial for growth, improved the yield and ultimately productivity of both hybrid rice and chickpea in areas with deficient available micronutrients in soil.
