An investigation was carried out during aman season, 2005 at the Field Laboratory of Agrotechnology Discipline, Khulna University, Khulna. Local rice variety Jatai tested against 4 different levels nitrogen viz. 0, 20, 40 and 60 kg N ha-1. The experimental results revealed that significantly affected plant height (cm), number tillers hill-1, weight 1000-grain (g), grain yield (tha-1), biologica...

the objectives of the present study were to evaluate spring wheat recombinant inbred lines (rils) of diverse origin by estimating genetic parameters viz., variability, character association, cluster analysis, and principal component analysis (pca) for spot blotch resistance and yield components at bhu agricultural research farm during 2010-2011. grain yield per plot was significantly and positi...

TaGW2 is an orthologue of rice gene OsGW2, which encodes E3 RING ubiquitin ligase and controls the grain size in rice. In wheat, three copies of TaGW2 have been identified and mapped on wheat homoeologous group 6 viz. TaGW2-6A, TaGW2-6B and TaGW2-6D. In the present study, using as many as 207 Indian wheat genotypes, we identified four SNPs including two novel SNPs (SNP-988 and SNP-494) in the p...

Rice grain yield and quality are two major foci of rice breeding. In this study, Chinese regional rice test data provide us the unique opportunity to analyze the relationship between yield and quality in rice, because China has an unusually wide range of rice cultivars. We analyzed the relationships between grain yield, yield components, and grain quality of 300 rice germplasms. Japonica was su...

in order to study the effect of the usage of vermicompost and mycorrhiza fertilizer usage on yield quantity and quality of soybean cultivar l17 in water deficit stress condition, an experiment was conducted as plots in a split at randomized complete blocks with four replications in agricultural research center in 2013 in khoramabad. the experiment treatments including irrigation in three levels...

in order to determine combining ability, heritability and heterosis of some agronomic traits in rice, 4 pure lines were crossed with 2 cytoplasmic male sterile testers. parents and their f1 progenies arranged in rcb design with three replications. analysis of variance showed significant differences among genotypes for all traits, except for filled grains/panicle. furthermore, the crosses effect...

in order to evaluate arbuscular mycorrhiza (glomuss mossea) and mycorrhiza-like (piriformospora indica) effects on yield, yield components and some morphological (cv. azar 2) traits of wheat (triticum aestivum l.) under water deficit stress, a pot experiment was conducted as factorial experiment based on completely randomized design with four replications. treatments were drought stress at thre...

to identify important attributes/factors that contribute to grain and biological yields of wheat, 9912 sets of diverse data from field studies were extracted, and supervised attribute-weighting models were employed. results showed that when biological yield was the output, grain yield, nitrogen applied, rainfall, irrigation regime, and organic content were the most important factors/attributes,...
