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.

A field experiment was conducted in popular carrot cultivar Nepa Dream using randomized complete block design (RCBD) with four replications for evaluating the effects of ten different treatments of soil conditioner in combination with organic and inorganic fertilizers on root growth and soil productivity. Soil samples from each microplot were also analyzed for soil texture, pH, organic matter, total nitrogen, available nitrogen, total phosphorus and total potassium before sowing and after harvest. Effects on soil was not significant in the single season experiment but effects of the treatments on the carrot root growth and production was significant. For higher root yield and biological yield, treatments Soil Conditioner +Micronutrient (Double Dose)+1/2 Recommended Dose of Fertilizer +1/2 Farm Yard Manure (T10) followed by Soil Conditioner +Micronutrient (Normal)+1/2Recommended Dose of Fertilizer +1/2 Farm Yard Manure (T7), and Recommended Dose of Fertilizer Full (T2) were found better whereas treatment T10 was found closer to T2 and Soil Conditioner +Micronutrient  (Double Dose)+Farm Yard Manure Full (T9) which showed higher mean performances for root diameter, cortex diameter and root length of carrot. In contrast, total soluble sugar as % brix was found less in the treatments involving one or more combinations of conditioner whereas highest for Farm Yard Manure and Recommended Dose of Fertilizer treatments either alone or in combination.  Thus, use of normal dose of GMT™ soil conditioner along with ½ Recommended Dose of Fertilizer and ½ Farm Yard Manure (T7) can be used as an alternative to T2 for higher carrot production which also can reduce the use of commercial inorganic fertilizers for improving soil fertility status. For organic carrot production at low cost, T9 can also be used as an alternative to other combinations of chemical fertilizers.

Mustard is locally popular with the name of tora/rayo/raichi is getting priority among the farmers due to its dual advantage of leafy vegetables and oilseed. With the objective identification of the potential mustard genotypes from the available gene pools, a coordinated Varietal Trial (CVT) was conducted in Oilseed Research Program, Nawalpur. A total of 14 mustard genotypes were evaluated in a randomized complete block design (RCBD) with three replications. The plot size was 10 m2 with five rows of 3-meter length maintaining inter-row of 40 cm and intra-row spacing of 15 cm. While depicting the yield, ICJ01-11 was considered the highest yielding genotype with the average yield of 521 kg/ha followed by ICJ9708 with the yield of 467 kg/ha and RH30 with the yield of 450 kg/ha. Due to the pivotal role of mustard as an oilseed production, it is indispensable to evaluate the available gene pool of local landrace, varieties and foreign genotypes of mustard to find out the highest yielding. So these promising genotypes can be used the in future to develop varieties of genotypes with high yield.

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
