Author(s): Ramawatar Meena
A field experiment was conducted during summer season 2014-15 at research farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi (U.P.). Treatment comprised with rock phosphate enriched compost and ordinary compost with recommended dose of nitrogen and potassium in Randomized Block Design replicated as thrice. The grain yield (9.68 q ha-1) and straw yield (39.23 q ha-1) were recorded with application of nutrients through 75% RDF + 6 t rock phosphate enriched compost as compared to control and other treatments. Maximum uptake of nitrogen, phosphorus, potassium and sulphur grain was recorded (34.09, 5.33, 17.66 & 2.29kg ha-1) respectively with application of 75% RDF + 6 t Enriched Compost ha-1. Similar trend was observed in greengram straw with application of nutrients through 75% RDF + 6 t enriched compost also. Soil fertility was gradually increased with the application organic sources. The pH, EC and Organic Carbon (7.57, 0.28 dSm-1 and 0.60%) were observed maximum with 100% RDF, 75% RDF + 6 t Enriched Compost and 100% RDF + 20 t FYM ha-1, respectively. The maximum availability of N and K (245.13 and 253.69 kg ha-1) was found with the application of 100% RDF + 20 t FYM ha-1 while P and S (22.66 and 19.26 kg ha-1) was found with the treatment of 75% RDF + 6 t Enriched Compost ha-1 in the post-harvest soil.
