ABSTRACT

A field experiment was laid out in randomized block design (RBD) with three replications and seven
treatments. The treatments were given : T₀ = Control; T₁ = RDF; T₂ = 100% ZnSO₄; T₃ = 100% Zn EDTA; T₄ = 50% ZnSO₄; T₅ = 50% Zn EDTA and T₆ = 50% ZnSO₄ + 50% Zn EDTA. Analysis of soil and physiological parameters was also done. Morphological, physiological, soil and biochemical parameters were analyzed. T₃ (100% Zn EDTA) led to the highest plant height followed by T₆ (50% ZnSO₄ + 50% Zn EDTA) taken at different time intervals viz., 30, 60 and 90 DAS. Tiller number was more in treatment T₃ (100% Zn EDTA). Grain yield was more in the treatment where only RDF was applied. In comparison, the straw yield was higher in T₄ (50% ZnSO₄). Results showed that RDF had more impact on the grain yield.
