Nutrient Content and Nutrient Uptake of Rice by The Impact of Inorganic, Organic, and Biological Sources of Nutrients in An Inceptisol Soil of Tamil Nadu

Abstract

Using the rice variety ADT-37, a field experiment was conducted in the rabi season of 2023 in Tamil Nadu.  The scope of the study is to find out the impact of different sources of nutrients on nutrient content and uptake of rice.  Most of the previous research work has combined inorganic and organic sources, or inorganic alone or organic alone or anyone with biological.  Here we have included inorganic, organic and biological sources of nutrients. The experiment included of nine treatments viz., T₁ – Control, T₂ - 100% RDF, T₃ - 125% RDF , T₄ - 100% RDF + Press mud @ 10 t ha^-1 + 2% Zinc Solubilizing Bacteria, T₅ – 100% RDF + Vermicompost @ 6 t ha^-1 + 2% Zinc Solubilizing Bacteria, T₆ – 100% RDF + Coirpith Compost @ 6 t ha^-1 + 2% Zinc Solubilizing Bacteria, T₇ – 125% RDF + Press mud @ 10 t ha^-1 + 2% Zinc Solubilizing Bacteria, T₈ – 125% RDF + Vermicompost @ 6 t ha^-1 + 2% Zinc Solubilizing Bacteria, T₉ – 125% RDF + Coirpith Compost @ 6 t ha^-1 + 2% Zinc Solubilizing Bacteria.  The result concluded that 125% RDF + Vermicompost @ 6 t ha^-1 + 2% Zinc Solubilizing Bacteria (T₈) resulted maximum values in nutrient content and significantly higher in nutrient uptake values.
