Trends in Biosciences

An experiment was conducted under South Gujarat agro climatic condition at Regional Rice Research Station, Navsari Agricultural University, Vyara, (Gujarat) during kharif-2012 with a view to study the effect of nutrient management through organic and inorganic sources in SRI cultivation. The experiment was laid out in split plot design having two main treatments (Green manuring (G1) and without green manuring (G0)) and five sub treatments viz., no manuring (M1), 100% recommended dose of nitrogen (RDN) in the form of chemical fertilizer (M2), FYM (M3), bio-compost (M4) and vermicompost (M5). Green manuring (G1) treatment remained significantly better than without green manuring (G0) treatment for grain yield and majority of yield attributes. Green manuring significantly improve yield in SRI cultivation. Similarly sub treatment M2 (100% RDN) found significantly superior followed by bio-compost treatment (M4). Looking to yield and cost benefit ratio 100% RDN found best in SRI.
