Effect of nitrogen and zinc management on nutrient content of Maize (Zea mays L.)

Abstract

A field experiment was conducted during Kharif season of 2024 at the Agronomy Instructional Farm, Rajasthan College of Agriculture, Udaipur, Rajasthan to evaluate to the effect of nitrogen and zinc management on nutrient content in maize (Zea mays L.).
The experiment followed a factorial randomized block design with 12 treatment combinations involving three of nitrogen management levels (100 % RDN through urea, 50% RDN through urea + two foliar spray of nano urea and 33.3% RDN through urea +
two foliar spray of nano urea) and four of zinc management levels (Control, soilapplication at 25 kg ZnSO4 ha-1, foliar spray of 0.5% ZnSO4 and foliar spray of 0.5 % nano zinc). The results revealed that the combined application of 100 % RDN through urea + soil application at 25 kg ZnSO4 ha-1 significantly enhanced nitrogen, phosphorus, potassium and zinc content in grain as well as stover.
