Title
Study the effect of phosphorus fertilization and foliar application of iron (Fe) on growth analysis of spring safflower variety
Authors
Abstract
Abstract:
In order to study the effect of chemical phosphorous fertilizer and foliar application of Fe on morphophysiological 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 replications. Two factors including three levels of phosphate chemical fertilizers (50,100 and 150 kg/ha-1) and two levels of foliar application Fe fertilizer (FeEDDHA) white density 1and 2 gr/lit-1. The highest harvest index, respectively, treated with 150 kg/ha-1 and 1 and 2 gr/lit-1 Fe foliar application was measured. The highest values of net assimilation rate, crop growth rate and viability of biomass (BMD) in the treatment of 150 kg/ha-1 phosphate were obtained. Treatment of 100 kg/ha-1 P had the greatest effect on leaf area index (LAI). It is worth noting that the spray solution 2 gr/lit-1 than 1 gr/lit-1 of iron had a greater effect on the characteristics of NAR, CGR, BMD.
