This experiment was conducted at the Agricultural Research Farm of Isfahan University of Technology in 2006 to evaluate the effects of row spacing and plant distance on the row on yield and yield components of sunflower, Hisun-36 hybrid. A split plot layout was used with a randomized complete blocks design and three replications. Row spacing (60 and 75 cm) was the main plot and plant distance o...

Under irrigation and in double-cropping system, a large amount of plant residue remains after harvest that along with the limited time for residue decomposition and complete seedbed preparation, necessitates reduced tillage and special residue management. In the present study, the effects of various seedbed preparation methods on vegetative growth, yield components and seed and oil yields of su...

safflower is a crop native to iran and could be improved in plant breeding programs by inter-specific crosses. this study was conducted to evaluate genotypes of safflower derived from interspecific hybridization for the relationships between some agronomic traits and yield components. the genotypes were planted according to a randomized complete block design with three replications at the resea...

Sorkhi, Farshad ,

In order to evaluate the effect of water stress on sunflower cultivars of Iroflor in different stages of growth and methods of biophosphate consumption, a factorial experiment was conducted in a randomized complete block design with four replications. Water deficit stress in four levels including control (non-stress), stress in vegetative stage, stress in reproduction stage and stress in both v...
