In order to evaluate effect of plant density and water deficit on the growth, yield and yield component of soybean, an experiment was carried out in split plot design based on RCBD with four replications at the research station of Seed and Plant Improvement Institute in Karaj-Iran in 2006. In this experiment, water deficit treatment in three levels was placed as main plot (water withholding at ...
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...
the evaluation of gene bank germplasm collection for morpho-physiological traits is important in the breeding programs. although phenotypic variation was considered, it is likely that this phenotypic variation is largely genetic and therefore directly useable for breeders, especially for those traits with high heritability such as heading and maturity time, plant height, kernel number and weigh...
karim as a new line (hamam-4: t.aest/sprw's'//ca8055/3/bacanora86 icw92-0477-1ap-1ap-4ap-1ap-0ap) was evaluated at gachsaran agricultural research station in 2004-2005. it was selected for its high grain yield (3975 kg ha-1) and included in advance yield trial in gachsaran, khoramabad, gonbad, moghan and ilam field stations in next growing season. average yield of this line and check ...
quantitative valuations of observed heterosis for 11 traits of 15 f1 hybrids generated by half diallel crosses of six diverse rice cultivars (domsefid, hashemi and binam, three iranian local cultivars; dorfak, kadous and ir30, three improved cultivars), were made in this study. fifteen f1 hybrids and their parents were evaluated in a randomized complete block design with three replications at t...
An experiment was conducted to investigate the heterosis in 12 F1 hybrids of durum wheat using agronomic and morphological traits. Parents were selected according to the estimated genetic distances based on the results of a two-year field experiment, which were then crossed to produce F1 hybrids. Twenty-three genotypes (including 11 parents and 12 hybrids) were evaluated using a randomized co...
abstract in order to study of relationship between timing and duration of phenological events and grain yield of wheat plants, an experiment was performed at moghan college of agriculture and natural resources-university of mohaghegh ardabili research farm during 2010-2011. the plant materials (81 wheat cultivars) were evaluated using a simple lattice design with two replications under irrigate...
Drought stress is one of the major limiting factors of crop yield. A field experiment was conducted to study the effects of drought stress on yield and yield components of nine bread wheat and one durum wheat genotypes during 2003-2004 growing season. The experiment was designed as two separate randomized complete blocks design with three replicates under well-watered and unwatered conditions...

The event of partly grain-free ear is a crucial problem which can result in severe reductions in corn yield. In a two year field investigation, during 2003-2004, an experiment was conducted to determine the effect of boron (B) and zinc (Zn) application on yield and yield components of corn (Zea mays L.) plants grown in a B and Zn-deficient calcareous soil (fine, carbonatic, thermic, Typic Hapl...
