Seed quality is the major concern for future crop production which largely depends on the nutrient we applied. To evaluate the effect of different doses of nitrogen and phosphorus on yield and seed quality of wheat an experiment was conducted during 2014/15 at agronomy research block of Agriculture and Forestry University. The experiment was designed on randomized complete block experiment with four levels of Nitrogen (0, 50, 100, and 150 kg N/ha) and Phosphorus (0, 25, 50, 75 kg P205/ha) Lab experiment was conducted to evaluate the germination and vigor test of the progeny seeds obtained from the mother plant. Highest grain yield (3.64t/ha) was associated with 100 kg N/ha which was statically similar with 150 kg N/ha, similarly highest grain yield (3.14t/ha) was associated with 75 kg P/ha which was at par with 50 kg P/ha and 25 kg P/ha. Highest germination percentage was associated with 150 kg N/ha (94.08) and 75 kg P/ha (93.66) Highest vigor was observed (36.5) at 100 kg N/ha which was at par with 150 kg N/ha whereas highest vigor was obtained at 50 kg P/ha (35.77) which was at par with 75 kg P/ha (35.71) Gross return, Net return and Benefit Cost ratio was highest at 100 kg N/ha which was at par with 150 kg N/ha. Similarly highest gross return (104.9 thousands) was observed at 75 kg P/ha, highest net income (54.81 thousands), and benefit cost ratio (2.105) was observed with 50 kg P/ha. Therefore for the better yield, good economic return and good seed quality application of nitrogenous fertilizers at 100 kg N/ha and phosphorus at 50 kg P/ha is useful under Chitwan condition.

The research was conducted under RCBD with three replication to study the inter relationships among traits affecting yield and its affecting character at National Maize Research Programme (NMRP), Rampur, Nepal in 2013. The eleven inbreeds line of maize variety at winter season in 2013 were evaluated for estimation yield and its affecting character. For efficient selection of grain yield, it is necessary to know relation of yield of maize and its morphological traits which are influencing on the grain yield. One of the objectives of this paper was to determine interrelationship between traits and the yields. Correlation coefficients among traits showed that yield was positively and highly significantly related with number of kernel rows per ear (0.788), number of kernels per row(0.571), ear girth(0.516), plant height(0.498), hundreds kernels weights(0.444) and significantly related with other character. .Number of Kernels rows per ear, number of kernels per row, plant height could be the important selection criteria in improving open pollinated maize varieties for high grain yield.Int J Appl Sci Biotechnol, Vol 3(3): 443-445

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.

Non-primed top quality seed of maize having cent-percent germination in lab resulted only 61% emergence in the field based on 4806 observations for non-primed seed while treated seed (priming cum incubation) recorded 82 % emergence in the field based on 4806 observations during first year. During second year experiment also non-primed top quality seed of hybrid maize having cent-percent germination in lab resulted 71.29% emergence while priming cum incubation treatment recorded 91.84% emergence. The result of both years clearly indicates the importance of seed treatment for maintaining the optimum plant population and there by insuring higher yield of winter hybrid maize.Int J Appl Sci Biotechnol, Vol 4(1): 113-116

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
