Abstract

Field experiment was conducted on groundnut during kharif, 2014 at College of Agriculture, Rajendranagar, Hyderabad to study the effect of four organics (vermicompost with P enrichment using 3 % rock phosphate, vermicompost prepared with mushroom spent substrate, vermicompost and FYM) at two levels of nitrogen (100 % RDN i.e., 30 kg ha-1 and 75 % RDN i.e., 22.5 kg ha-1) along with control (No NPK but gypsum @ 500 kg ha-1 at flower initiation) and absolute control (no NPK and gypsum) to find out the effect of different organic sources on nutrient use efficiencies viz., partial factor productivity, agronomic efficiency, partial nutrient balance, apparent recovery efficiency, internal utilisation efficiency and physiological efficiency. Significantly higher agronomic efficiency and partial productivity factor of 86.7 and 174.63 are obtained due to application of 75% RDN through of P (3%) enriched vermicompost; while apparent recovery efficiency of N was significantly higher (4.08 and 4.03 to absolute control and control with applied gypsum) when applied at 100% RDN level.
