EFFECT OF SPRAYING IRON AND ZINC ON SOME YIELD COMPONENTS OF WHEAT (Buhooth 7)

Abstract

To study the effect of different concentrations of iron and zinc on yield component of wheat (Triticum aestivum L.) Buhooth 7, field experiment was conducted at Agronomy Dept. Field, College of Agric. Baghdad Univ. in a silty clay loam soil, crop requirement of N,P and K fertilizers were added . Iron sulfate and zinc sulfate were sprayed at concentrations of (0, 50, 100) mg.l-1 for both at three stages of plant growth (vegetative growth, Boating and flowering) stages. Randomized complete block design was used with three replicates. Results showed that all concentrations of Fe, Zn and their interactions significantly effect on all parameters of grain yield, the heightens of grains yield of interaction treatment (Fe2 x Zn2) which was (5.88) t.ha-1 as compared with control treatment which produce (4.30) t.ha-1.
