<p class="Abstrak"><span>Cowpea [<em>Vigna unguiculata</em> (L.) is more tolerant to drought and acid soil, compared to the other leguminous crops. A total of 150 cowpea germplasm accessions were grown at Muneng Research Station (Probolinggo) during dry seasson of 2014, using a randomized block design, with two replications. Each accession was planted in two rows, of 4 m. Among the total accessions they varied in qualitative and quantitative traits. Most of the accession had ovate leaf shape, purple flower color, cream color of mature pod, and brown to yellowish grain color. Grain yield had a high phenotipic and genotypic coefficient of variation. Low phenotipic and genotypic coefficient of variation was shown on days to 50% flowering and days to physiological maturing. Of the eight variables characterizing the cowpea accessions 64.2% could be explained by three factors. The first factor related to grain yield components (number of fertile nodes, number of branches, and grain weight), second factor associated with crop cycles (date of flowering and harvesting), and the third factor associated with the supporting factors (plant height, pod length, and number of grains per pod). The cowpea germplasm could be divided into three groups. Date of flowering and pod maturing were a determinant variable discriminant function. Group I consisted of 70 accessions, dominated by accessions with early maturing, medium plant height, long pod, high number of grains per pod and high grain yield. Group II consisted of 47 accessions with medium pod maturing, short plants, short pod, low number of grains per pod and low grain yield. Group III consisted of 33 accessions, characterized by medium maturing, high plant, short pod, high number of grains per pod and high grain yield. Accessions of cowpea in group I and III have a high yield and are prospective for further utilization.</span></p>

This study was conducted during summer 2015 at Regional Agriculture Research Station, Dipayal, Doti, Nepal to estimate the genotypic and phenotypic variability, heritability, genetic advance and correlation on grain yield and yield associated traits using 26 advance genotypes of lowland irrigated rice. Analysis of variance revealed the existence of significant difference for days to flowering, maturity, plant height, panicle length, thousand grain weight and grain yield. High heritability was estimated for days to flowering (0.88), maturity (0.79), thousand grain weight (0.48) and plant height (0.43) suggesting these traits are under high genetic control. High phenotypic variation was observed for grain yield (24.87%), number of grains/panicle (22.45%), number of panicles/m2 (20.95%) and straw yield (20.75%) while grain yield had medium (12.02%) and remaining traits showed low genotypic coefficient of variation (<10%). High phenotypic coefficient of variation estimated as compared to genotypic coefficient of variation showed environmental influence on the expression of traits. Grain yield (11.98) and days to flowering (10.32) showed medium and remaining traits sowed low genotypic advance as percent of mean. High to low heritability with moderate to low genotypic advance as percent of mean suggested these traits were governed by non additive gene thus direct selection is not beneficial. Further improvements on yield potentiality and yield traits on these genotypes are suggested by creating variation and selection. Panicle length (r = 0.230), days to flowering (r = 0.247), effective tillers (r = 0.488) and straw yield (r = 0.846) manifested significant positive association with grain yield indicating that yield can be increased if selection applied in favor of those yield components.

Aim: Present study endeavors to explore the genetic variability for various agro-morphological and quality traits as well as to delineate the association between grain yield and its yield attributing components Study Design: Randomized Complete Block Design Place and Duration of Study: Division of Plant Breeding and Genetics, She-e-Kashmir University of Agricultural Sciences and Technology of Jammu during kharif 2020. Methodology: A experiment was carried out to determine the association between grain yield and yield attributing components among advanced breeding lines of rice to establish a well grounded selection criteria for developing rice varieties with improved grain yield. Phenotypic coefficient of variation (PCV) was found to be relatively greater than the genotypic coefficient of variation (GCV) for most of traits indicating role of environment in the phenotypic expression of traits. Characters viz., plant height, total number of tillers per plant, number of effective tillers per plant, panicle length and grain yield per plant exhibited high heritability coupled with high genetic advance indicating their efficient inheritance from preceding generations. Results: Association studies indicated that characters viz., Plant height, total number of tillers per plant, number of effective tillers per plant, panicle length, 1000 grain weight and grain yield per plant had a significant positive relationship with grain yield per plot indicating their role in breeding rice varieties for higher grain yield. Conclusion: Cause and effect relationship revealed that traits viz., days to 50 per cent flowering, total number of tillers per plant, days to maturity, panicle length and grain yield per plant can be exploited for indirect selection for improving grain yield.

In order to reach an optimum and sustainable production, growers must know the fertilizing nutrient sources and their application rates. The present study aimed to determine the effect of different organic and inorganic source of fertilizers on growth and performance of rice. A field experiment was conducted at Regional Agriculture Research Station, Parwanipur, Bara, Nepal during summer season of 2013. Rice variety ‘Hardinath 1’ was used in these experiments. Treatments included a combination of organic and inorganic nutrients at eight rates (control, recommended dose of NPK, ½ NPK+FYM 10 t ha-1, ½ NPK+20 cm crop residue, ½ NPK+Chicken manure 10 t ha-1, ½ NPK+Vermicompost 10 t ha-1, FYM 10 t ha-1 and FYM 20 t ha-1).The experiments were laid out in Randomized Complete Block Design with four replications. Treatments produced significant results for plant height, number of tillers per square meter, panicle length and grain yield but thousands grains weight was insignificant. Result showed that application of half of recommended N: P2O5: K2O from the inorganic fertilizer sources along with soil incorporation of 20 cm crop residue produced significantly higher value for plant height, number of tillers per square meter, panicle length and Grain yield. Treatments did not produce significant effect on after harvest soil properties: pH, organic matter, nitrogen, phosphorus and potassium content.

Rice wheat cropping system prevailed in more than fifty percent areas of rice belt of central and upper Punjab. In this area yield of wheat is curtailed every year due to late harvesting of rice crop. In addition to this, lack of machinery for direct sowing of wheat into combine harvested rice is a major limitation for timely wheat sowing due to presence of heavy straw load dropped by the combine harvester. A field experiment was planned and executed during two consecutive years 2017-18 and 2018-19 at Agronomic Research Station Farooqabad to evaluate the various stubble management techniques for the sowing of wheat in a rice-wheat cropping system. The Experiment consist of four treatments Happy seeder (Zero tillage), conventional sowing without burning of rice stubble, Rotavator two times, and Conventional sowing with the burning of rice stubble. The trail was arranged as a Randomized Complete Block Design with four replications having a net plot size of 8 m x 20 m. The Treatments have significant effects on Plant height, Number of productive tillers, 1000- grain weight, and grain yield. Maximum plant height (94.74 and 94.25 cm), numbers of productive tillers/m2 (324.00 and 322.25), 1000-grain weight (36.35 and 36.20 g), grain yield (3780 and 3613 kg/ha), and benefit-cost ratio (2.54 and 2.43) were recorded from the treatment happy seeder (Zero tillage) during both years respectively. It is concluded that the sowing of wheat with a happy seeder (Zero tillage) is an appropriate technique in the rice-wheat cropping system by protecting the environment and soil health from the burning of rice stubbles.

The aim of present investigation was to study the effect of foliar application of gibberellic acid (Progibb 40% WSG) spraying at 4-5 leaves stage of the maize crop. Two field experiments were conducted during kharif 2014 and rabi 2014-15 at Research Farm, Zonal Agricultural Research Station, Jhabua. Seven treatments (T = 20, T 30, T 40, T 50 T 60 gibberellic acid g/ha, Tricontanol 1 2= 3= 4 = 5= 0.1%= 250 ml/ha and control) were tested in randomized block design with three replications. Results showed that variation in different doses of gibberellic acid had significant effect on growth character (plant height and silking) and yield attributes (no. of cobs/plant, cob length, no. of grains/cob and cob weight/cob); grain yield and stover yield of maize in both the seasons. Higher values of plant height (197.33 and 205.5 cm) and silking (53.67 and 54.67) was recorded with the spraying of gibberellic acid @ 60 g/ha in both the seasons, respectively. Similarly the higher yield attributes viz., no. of cobs/plant (1.48 and 1.49), cob length (17.40 and 17.78 cm), no. of grains/cob (443.33 and 456.67) and cob weight/cob (93.2 and 97.32) were recorded with the application of gibberellic acid @ 50 g/ha in both the seasons, respectively. Application of gibberellic acid @ 50 g/ha produced highest grain yield (3522 and 4277 kg/ha) and stover yield (51.05 and 5413 kg/ha) which was statistically at par with doses of 40 g/ha, 60 g/ha and tricontanol 0.1% @ 250 ml. The maximum gross return (Rs. 56,347 and 65,854), net return (37,722 and 47,229), B: C ratio (3.03 and 3.54), production efficiency (32.49 and 37.19 kg/ha/day) and economic efficiency (339.84 and 410.69 Rs./ha/day) recorded with gibberellic acid @ 50 g/ha. Enhancing of production, productivity and profitability of maize under Jhabua Hill of Madhya Pradesh gibberellic acid applied @ 50 g/ha at 4-5 leaf stage of crop.
