Effect of iron and zinc enriched organics on nutrient content and uptake by wheat in loamy sand

Abstract

A field experiment was carried at the Agronomy Instructional Farm, Department of Agronomy, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to study the effect of iron and zinc enriched organics on nutrient content and uptake of wheat in loamy sand (Typic Ustisamments) during rabi season of 2017-18. The results revealed that the concentration of N in grain and straw was increased significantly due to an application of 5 t FYM ha-1 and 2 t VC ha-1 along with recommended dose of fertilizer (RDF) but remain at par with application of either 5t FYM ha-1 or 2 t VC ha-1 along with RDF. However, significantly higher content of Fe and Zn by grain and straw and uptake of N, P, Fe and Zn by grain and straw of wheat were obtained by application of vermicompost @ 0.2 t ha-1 enriched with 5.00 kg Fe and 2.50 kg Zn along with RDF as compared to control (RDF).
