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.
