بررسی اثر کود فسفر و محلول پاشی آهن بر خصوصیات مورفولوژیکی و فیزیولوژیکی گلرنگ بهاره

bstract:
In order to study the effect of chemical phosphorous fertilizer and foliar application of Fe on morphological and physiological traits of spring safflower variety (IL111), an experiment was conducted in 2012 cropping season in Shahed university’s farm. The experimental design was factorial in basis of randomized complete blocks with three replication. The main-plots were different three levels of phosphate chemical fertilizers (50,100 and 150 kg/ha-1) and sub-plots were two levels of foliar application Fe fertilizer white density 1and 2 gr/lit-1. The result has been showed that different treatments were different and significantly effect on number of capitula per plant, number of seed per plant, weight of 1000 seeds, as 150 kg/ha-1 phosphate and 2 gr/lit-1 Fe foliar application treatment have highest effect on number of capitula per plant, and 150 kg/ha-1 phosphate and 1 gr/lit-1 Fe foliar application treatment were maximum effect on number of seed per plant and weight of 1000 seeds also. The highest seed oil content in treatments with 100 kg/ha-1 phosphate and spray solution 1 and 2 gr/lit-1 iron, respectively. Treatment of 150 kg/ha-1 phosphate and 2 gr/lit-1 Fe foliar application had more impact on yield. The highest biological yield, in treatments 150 kg/ha-1 phosphorus fertilization and foliar application of 1 and 2 gr/lit-1 iron was obtained.
