Influence of different agronomic strategies on growth and yield of rice

The field Experiment was conducted at Annamalai University, Experimental Farm, Department of Agronomy during Kuruvai season of June – September, 2023, to study the influence of different agronomic strategies on growth and yield of rice. A short duration rice variety ADT 43 was selected for the study. The field experiment was laid out in Randomized Block Design (RBD) with nine treatments in three replications. Based on the experimental results, it may be concluded that the application of 50% RDN + RDF (P&K) + foliar application of nano N +ZnSO₄ + FeSO₄ at 25 and 45 DAT (T₉) effectively recorded highest crop growth rate, plant height, leaf area index, number of tillers hill^-1 and dry matter production. The treatment T₁ recorded the lowest values of growth and yield.
