Effect of Organic and Inorganic Fertilizers on Soil Physical Properties & Nutrients Content and Uptake of Summer Green Gram

Abstract

The investigation was carried out during summer season to know the effect of different organic and inorganic fertilizers on physicochemical properties of soil & content and uptake of plants. The experiment was laid out in factorial randomized block design (FRBD) followed by twelve treatments with four replications. Water holding capacity, bulk density, porosity of soil was not significantly influenced by application of organic and inorganic fertilizers at harvest. Application of vermicompost @ 1.0 t ha-1 recorded significantly higher nitrogen content & uptake in seed and stover and potassium content in stover of green gram which was at par with incorporation of FYM @ 4 t ha-1 but phosphorus content & uptake was not significantly influenced by either incorporation of FYM or vermicompost or inorganic fertilizer. The use of 100% RDF (20 kg N + 40 kg P2O5 ha-1) resulted in significantly higher uptake of nitrogen and potassium by seed, stover and total uptake by crop and were at par with the application of 75% RDF (15 kg N + 30 kg P2O5 ha-1). Nitrogen, phosphorus and potassium content & uptake in seed, stover and total uptake of green gram was significantly higher recorded with the incorporation of FYM @ 4 t ha-1 which was at par with application of vermicompost @ 1 t ha-1. Application of farm yard manure @ 4 t ha-1 or vermicompost @ 1 t ha-1 along with inorganic fertilizers @ 75% RDF (15 kg N + 30 kg P2O5 ha-1) is best suited for improving physico-chemical properties of soil and nutrients content & uptake of green gram.
