chickpea (cicer arietinum l.) is a native crop of asia which is grown worldwide including iran.in this study,different selection criteria including correlation,regression and path analysis were used to improve yield.the experimental design was split plot with rcbd replicated four times in which three sowing dates (5 january,4 february,and 5 march) were used in main plots and four genotypes;two ...

in order to study the effect of spraying of abscisic acid on yield and yield components of chickpea (cicer arietinum l.) under rainfed and supplementary irrigation, a field experiment was conducted in 2010 in agricultural research station of ilam university. a split factorial experiment based on a randomized complete block design was conducted. main plots were composed of two levels of irrigati...

two year field experiment was carried out on two early maturing varieties of soybean (glycine max (l.) men.) bred in russia. the purpose was to investigate the possibility of production and to study the effects of nitrogen supply on soybean seed yield and yield components. a range of zero to 100 kg n ha in 1995 when plants suffered from water deficiency and zero to 100 kg n ha -1 in 1996 when p...

In most southern provinces of Iran, Soil Salinity is a growing problem particularly in the irrigated agricultural areas and has been found to reduce crop yields. In order to investigate the role of pod removal in seed germination, seedling growth and antioxidant enzymes activity in annual medics (Medicago scutella L.) under salinity stress conditions, a factorial experiment was conducted at Col...

to evaluate canola cultivars response to physiological characteristics and grain yield end seasonal drought stress in weather condition of ahvaz, farm experiments were done at research farm of khuzestan agriculture and natural resources center. during 2007-2008 and 2008-2009 crop years. farm test comprised drought stress was done as split plot form with randomize complete block design with four...

abstract the present study was aimed to investigate the planting dates effects on yield associated traits and also determining stability of the result of factor analysis and stepwise regression analysis in different planting dates of rapeseed genotypes at biekol agriculture research station during 2011-12 cropping season. result of split plot analysis exhibited significant genotypes effects for...

A field experiment was conducted for two consecutive seasons (2009/10 and 2010/11) in the Demonstration Farm of the Faculty of Agriculture at Shambat-Sudan, to study the interactive effect of nitrogen fertilization and rhizobium inoculation on nodulation and yield of soybean (Glycine max [L.] Merrill) plants. The experiment was laid out in a randomized complete block design with four replicatio...

BACKGROUND AND AIMS Using two parental clones of outcrossing Trifolium ambiguum as a potential model system, we examined how during seed development the maternal parent, number of seeds per pod, seed position within the pod, and pod position within the inflorescence influenced individual seed fresh weight, dry weight, water content, germinability, desiccation tolerance, hardseededness, and subs...

knowledge of the relation between agronomical traits with economical yield is very important in crop improvement and breeding. in order to study of genetic diversity and identifying yield components, 568 kabuli type germplasm and 390 desi type chickpea germplasm that were available in pulses collection of faculty of agriculture, university of tehran, was investigated in this research in 2009 in...
