Barley, being a tremendous opportunities crop, we are far back regarding study, research and utilization. An experiment was conducted 2014-2015 to evaluate the barley genotypes for their yield attributing traits and correlation and causation. Eleven yield contributing traits viz., days to booting, heading and flowering; peduncle length, spike length, plant height, flag leaf area, flag leaf-1 area, thousand grain weight, biological weight and yield per hectare were recorded. High significant variation among genotypes was found for traits under study. Genotypes SBYT3-13#1115 (1960 kg), 14-SB-NAK-MR#17 (1760 kg) and AM POP#26 (1660 kg) were found to be superior for their per se performance based on grain yield per hectare, yield attributing and other quantitative traits. Thousand grains weight (0.333) had positively highest significant correlation with grain yield per hectare followed by spike length (0.310). Grain yield per hectare showed negative highly significant correlation with days to flowering (-0.796) followed by days to heading (-0.761) and days to booting (-0.663). Peduncle length (0.229), plant height (0.226), biological weight (0.181) and flag leaf area (0.032) were positively correlated with grain yield per hectare while flag leaf-1 area(-0.029) was negatively correlated. Thus, selection for genotypes with higher thousand grain weight and spike length accommodating earlier days to flowering, heading and booting is a prerequisite for attaining improvement in grain yield per hectare.

The present study was performed in a randomized complete block design with three replications to identify higher yielding genotypes and putative traits for grain yield improvement under a rainfed environment. Genotypes recorded highly significant variation for most of the observed agro-morphological traits except the number of effective tillers/m2. IR102774-31-21-2-4-7 (5.40 t/ha) followed by IR99739: 2-1-1-2-1 (5.22 t/ha), and IR103587-23-2-1-B (5.05 t/ha) respectively were the higher grain yielders. These high yielders were among the sets of early flowering (85-96 days) and maturing (120-130 days) genotypes. Plant height (PHT-86.62% and 25.69%), harvest index (HI-87.17% and 44.66%), and thousand-grain weight (TGW-71.06% and 30.05%) recorded high heritability values coupled with higher genetic advance as a percentage of the mean (GAM). IR102774-31-21-2-4-7 produced superior agro-morphological character for several traits like grain yield, thousand-grain weight, biological yield, plant height, and days to flowering and maturity. Plant height, biological yield, harvest index, days to flowering, and maturity were highly associated with grain yield and had medium to high heritability and GAM values. Therefore, these traits might be of importance for selection in grain yield improvement of rice under rainfed lowland conditions.

In Recent years, cultivation of Mustard (Brassica juncea) is growing popularity but there is lack of suitable high yielding and oil contenting variety in Nepal.  With Objective of identifying and releasing of high yielding variety, evaluation of exotic genotypes were done in the research field and farmers field. Coordinated Varietal Trial (CVT) was conducted for three years in three different location (Nawalpur, parwanipur and Khajura) in RCBD design.   4 Elite genotypes were selected and further evaluate under Coordinated Farmer Field Trial (CFFT) for 5 years where each farmer was considered as Replication.  Nutrients Analysis was done to find out the moisture, oil and protein content of selected elite genotypes.  In combined   ANNOVA of CVT, ICJ 9704 was found to be high yielding genotypes.  Similarly, In CFFT, genotypes was significantly for yield where   ICJ 9704 produced highest yield (906.75 kg/ha) where as   Divya, Pusa Jagarnath and Krishna produced yield of 798.12 kg/ha, 790 kg/ha and 767.392 kg/ha. ICJ 9704 has high oil content 37.3 % with   36.3 % protein content. In 2017, ICJ 9704 was release as Morang rayo and was recommended to grow in the terai and inner terai. Hope this variety will be popular among mustard growing farmer and will help to meet the national demand of the Nation.  Int. J. Appl. Sci. Biotechnol. Vol 8(4): 454-456

An experiment was conducted in factorial design with three replications in Nawalpur, Sarlahi, Nepal in 2018 and 2019 to investigate the impact of calcium and phosphorous application on yield and yield components of groundnut (Arachis hypogaea L.). Baidehi variety of groundnut was used. Calcium concentrations in three levels (0, 110, and 165 kg ha-1 from Gypsum) and phosphorous rates in three levels (0, 25, and 50 kg ha-1 from SSP) were used in this study. The application of calcium had a major impact on pod production, quantity of filled pods, and hundred seed weight, with 165 kg ha-1 calcium from gypsum performing significantly better than the others. The highest pod yield (2006 and 2477 kg ha-1) was obtained from calcium 165 kg ha-1 in 2018 and 2019 respectively. Calcium application (165 kg ha-1) increased the mean pod yield by 24% compared to the control. Control plots resulted in more than 13% empty pods (pops) compared to when applied with 165 kg Ca ha-1. Phosphorus was rich in the inherent soil leading to no significant effect on the yield components. According to the findings of this research, efficient fertilizer application, especially calcium and phosphorus, is critical for groundnut nutrition and pod filling.
