EFFECT OF FOLIAR APPLICATION OF IRON AND ZINC ON SOME VEGETATIVE PROPERTIES AND BIOLOGICAL YIELD OF WHEAT IPA 99 (Triticum aestivum L.)

Abstract

Abstract:An experiment was conducted at College of agriculture, Field Crop Production Department, to study the effect of spraying concentrations of Fe (0, 50 and 100) mg.L-1 and Zn (0, 50 and 100) mg. L-1 and their interactions on some vegetative properties and biological yield of wheat IPA 99, at silty clay loam soil, classified to Typic Torrifluvent. Requirements of N, P and K were added Concentrations’ of Fe and Zn as sulfates were sprayed 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 were significantly effect in increasing all parameters of the study compared with control treatment. The higher values were resulted from the effect of interaction of the higher concentration of Fe and Zn for parameters of plant height (cm), flag leaf area (cm2), No. of tillers per plant (No.), chlorophyll index (spad unit) and biological yield (T.ha-1) and they were 99, 40.1, 52.7, 10.00, and 13.39 respectively.
