EFFECT OF DIFFERENT GENERATION OF NITROGENOUS COMPOUNDS ON NUTRIENT UPTAKE AND YIELD OF RICE (Oryza sativa L.) UNDER DIFFERENT TRANSPLANTING TECHNIQUES

A field experiment was carried out in a farmer's field in the Chidambaram block during the June – September, 2021 to determine the " Effect of Different Generation of Nitrogenous Compounds on Nutrient Uptake, Yield and Economics of Rice (Oryza sativa L.) under Different Transplanting Techniques." The experiment was carried out in a split-plot design, comprising three methods of crop establishment viz., mechanical transplanting, the system of rice intensification (SRI), and conventional transplanting in the main plot, as well as five nitrogen management methods viz., 100% RDN through urea, 100 % RDN through vermicompost, 50% RDN through urea + 50% RDN through Nano urea, 50% RDN through vermicompost + 50% RDN through Nano urea, and 100% RDN through Nano urea in sub plot. The results of the experiment demonstrated that among the establishment techniques and nitrogen management practices tested, the System of Rice Intensification and application of 50% Inorganic Nitrogen in combination with 50% Nano Nitrogen has shown highest nutrient uptake and grain yield.
