drought stress is one of the most important abiotic stresses which can affect the growth of a plant, thereby curbing crop yield. identification of effective morphological traits is the main aim of each breeding program. our objective was to identify agronomic traits associated with changes in grain yield of wheat under irrigated and drought conditions. to address this objective, grain yield and...
Rice is a worldwide important grain crop, which is considered as the main food and most important source of providing protein and calories for people in the world. Correlation analysis of different traits and yield components with the grain yield is a very important issue in the selection and breeding programs of genotypes. The experiment was performed in the form of completely randomized ...
Optimum rice population densities and the response of rice yield and yield components to population densities and planting pattern are important factors helping rice producers and researchers to achieve maximum productivity. For this reason, a randomized complete block design experiment was conducted during the summer of 1995 at Isfahan University of Technology Research Farm located at Lavark, ...
abstract in order to study the inheritance of grain yield and its components in bread wheat, two cultivars, karchyya(drought and salinity tolerant) and gaspard (sensitive to drought and salinity stress) were crossed.parents together with f1, f2, f3, bc1and bc2 generations were evaluated using a randomized complete block design with three replications in 2008-2009 growing season.grain weight per...

although water deficiency has been seriously taken up as a subject in reducing crop production in arid and semi–arid areas, nevertheless little information has been published regarding its effects on seed quality. to evaluate the effects of irrigation regimes (full irrigation (control), irrigation until flowering stage, irrigation until doughing stage and irrigation until eight-leaf stage) on g...
In order to investigate the effect of silicon application on some physiological characteristics, yield and yield components, and grain mineral contents of bread wheat (Triticum aestivum) under water stress condition, an experiment was conducted in Ramin Agriculture and Natural Resources University, Khuzestan, in 2012. The experiment was arranged in split-plots design in RCBD (Completely Randomi...
This experiment was laid out in order to evaluate the effects of different biofertilizers on yield components of barley. The experiment was a factorial design with three replications. Treatments were three nitrogen biofrtilizers (Nitroksin, Nitrokara and Supernitroplass) and three phosphate biofrtilizers (Phosphate barvar2, Biozarr and Superplass) with control for them and yield components we...
to study the nature and magnitude of gene effects, heritability and number of effective factors for grain yield and some yield components in rice, six generations viz., p1, p2, f1, f2, bc1 and bc2 were prepared from the crosses of shapasand × irfaon-215 and irfaon-215 × saleh and grown in a randomized complete design with three replications. results of analysis of variance showed significant di...
during grain development, appropriate water status of soil has key importance for starch accumulation in grains and hormone changes. for this, the study carried out on two iranian wheat cultivars pishtaz and karaj 3 in a factorial experiment based on randomized complete block design with three replications under irrigated and drought in a field experiment at research farm of agriculture college...
