Effect of iron and zinc as foliar application on sorghum grown in a calcareous soil
Abstract: Field experiment was conducted at Noubaria agriculture research station farm on a Calcic xerosol 26% CaCO3, to study the effect of iron and zinc spraying in two forms, mineral and chelated on sorghum yield. Iron and zinc as mineral sources (FeSO4 & ZnSO4) were dissolved in water, while chelated sources (Fe EDDHA & Zn EDTA) were dissolved either in water or in 20% methanol solution. obtained results revealed that: Spraying iron in different forms and rates gave a significant increase for each of grain yield, harvest index, contents of N& Zn in grains, Zn in peduncles, Fe in leave, K and Fe in stems. Also, spraying zinc in different forms and rates gave a significant increase for each of grain yield, dry weights, harvest index, contents of N, K & Zn in grains, P, K, Fe and Zn in stems in generally, sorghum grain under experimental conditions were needy to cover the applied treatments of both iron and zinc spraying regardless the form dispersion agent and thus, the more cheap form of them in water solution could be recommended for a foliar application
