Response of yield and yield components of safflower cultivars to simultaneous cropping system

In order to response of yield and yield components of safflower cultivars to simultaneous cropping with some of crops, this study was carried out in field of Kashan city of Esfahan province in 2013. A factorial arrangement of treatment in a randomized complete block design with three replications was used. Spring safflower cultivars (V1= Faraman, V2= Goldasht, V3= Esfahan local, V4= Soffeh) and Simultaneous cropping treatment, (S1= Cultivation of safflower chickpea, S2= Cultivation of safflower alfaalfa, S3= Cultivation of safflower onion, S4= Cultivation of safflower) were assigned in plots. Each sub plot consisted of 4 rows, 5 m long with 60 cm between rows space and 4 cm between plants on the rows was used. In this study characteristics such as: days to 50% bolling, height of plant, number of boll per plant, number of grain per boll, weight of 1000 grain, wet weight of plant in m-2, number of grain per m-1, grain yield and grain yield of onion were assessed. Results indicated that the effect of safflower cultivars on the characteristics such as: days to 50% bolling, height of plant, number of boll per plant, number of grain per boll, weight of 1000 grain, wet weight of plant in m-2, number of grain per m-1, grain yield was significant. Effect of Simultaneous cropping treatment on the characteristics such as: number of boll per plant and number of grain per boll was significant, too. The maximum and minimum of grain yield (2084 and 1710 kg ha-1) were obtained with the Esfahan local and Soffeh cultivars, respectively.
