A 3- years (2015, 2016 and 2017) field study was carried out at National Wheat Research Program, Bhirahawa, Rupandehi, Nepal to evaluate the influence of crop residues and nitrogen levels on rice. The experiment was conducted in split plot design with three replications. Main plots were two crop residue levels (with crop residues of 30 cm wheat stubble and without crop residues) and sub plots c...

Yield and grain quality maps have been produced at full-scale field trials within a 10.5 ha-1 field for four different nitrogen strategies. Grain samples have been collected directly from the grain flow of a combine harvester and analysed for quality in the laboratory and merged with the yield meter registrations. Within the field great variance was observed in yield and grain quality. This pap...

In order to improve the prediction precision of grain yield, the grey system theory and the fuzzy neutral network are combined to construct the combined prediction model, which is applied in predicting the grain yield. Firstly, the basic theory of the grey system theory is analyzed. Secondly, the mathematical model of fuzzy neutral network is studied, and the corresponding algorithm procedure i...

to study and determine  effect of salinity on relationship between  agronomic  characteristics and grain yield, 167  of  the  seri/babax recombinant wheat inbred  lines (ril) together with two parents were evaluated using alpha latice design with two replications under two conditions (salt stress and normal), in zabol field station in 2011-12 cropping season. fourteen  traits  including: some a...

introduction soybean (glycine max (l.) merrill) is a leguminous annual crop belonging to the fabaceae family, that because an important source of food containing 20 to 28 grain oil percent and high protein is the most important oilseed of worldwide interest. recently, cultivation of this plant is considered as a valuable oil plant in crop rotation. drought, salinity, heat and freezing are envir...

Before selecting genotypes for nutritional quality characters (protein, oil and micronutrients content) and anti-nutritional factor (phytic acid), it is important to know how much selection is likely to affect yield. Using a diverse range of genotypes, relationships between quality traits with yield and yield attributes in pearl millet were investigated. The number of productive tillers, panicl...
