ABSTRACT
Field experiment was conducted during kharif season, 2014 at College of Agriculture, Rajendranagar, Hyderabad to study the effect of four organic manures (phosphorus enriched vermicompost with rock phosphate 3 per cent, vermicompost prepared with mushroom spent substrate, vermicompost and FYM) at two levels of nitrogen (100 per cent RDN 30 kg ha-1 and 75 per cent RDN 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) on yield and nutrient uptake of organically grown table purpose groundnut. Phosphorus enriched vermi compost using rock phosphate 3% has more phosphorus content (2.15 %) and vermi compost prepared from mushroom spent substrate has more potassium content (2.74 %).The results showed that growth parameters, yield and yield attributes and nutrient uptake of (N, P, K, Ca and S) groundnut were higher with application of 100 per cent RDN through vermicompost enriched with rock phosphate 3 per cent and was at par with 100 per cent RDN through mushroom spent substrate based vermicompost. Bulk density, pH and EC of soil was not significantly influenced by the organic nutrient management. However availability of OC , N, P, K, Ca, S in the soil was significantly higher with application of 100 percent RDN through vermicompost enriched with rock phosphate and was at par with 100 per cent RDN through vermicompost prepared from mushroom spent substrate.
