effects of foliar application of p, zn and fe on grain yield and yield components of chick pea

to evaluate the effects of various levels of phosphorous and foliar application of iron and zinc on grain yield and yield components of chick pea (ciceraireintinum l.), an experiment was conducted on split plot factorial based on randomized complete block design with three replications during 2010- 2011 growth season at the agricultural college research farm, lorestan university. factors included phosphorous fertilizer at three levels (p1=0 kg/ha, p2=100 kg/ha, p3=200 kg/ha, soil application) in the main plots. fe and zn each at three levels (f1, z1=0, f2, z2 = 0.3 and f3, z3 =0.6 percent, foliar application) were placed in the sub plots. the results showed that p, fe and zn levels had significant effects on grain yield, number of pod per m2 and 100 seed weight. interaction effect of p and fe was significant on biological yield, grain yield, 100 seed weight and number of pod per m2. also interaction effect of p and zn was significant on grain yield. interaction effects of p, fe and zn were significant on grain yield, 100 seed weight and biological yield. the maximum grain yield was obtained from p3f3z3 treatment with grain yield 1228 kg/ha. it seems p3f3z3 treatment is optimum amount for chick pea (cultivar ilc482) under the study condition.
