Influence of Vermicompost application alongwith Nitrogen on Growth, Nutrients uptake, Yield Attributes and Economics of Rice (Oryza sativa L.)
Abstract: <div>A field experiment was conducted to study the effect of vermicompost application on growth, nutrients uptake, yield attributes</div><div>and economics of rice (variety ADT 43) at Agricultural College and Research Institute, Madurai during kharif season. Five main</div><div>plot treatments viz., M1- control, M2 - farmyard manure @ 12.5 t ha-1, M3- vermicompost @ 1.5 t ha-1, M4 - vermicompost @ 2.0 t ha-</div><div>1 and vermicompost @2.5 t ha-1 and three sub plot treatments viz., S1 – leaf colour chart critical value less than 3, S2 - leaf colour chart critical value less than 4 and S3- Recommended dose of nitrogen were replicated thrice in a split plot design. The results revealed that growth and growth attributes, yield attributes, N, P and K uptake and benefit :cost ratio were recorded higher</div><div>under application of vermicompost at the rate of 2.5 t ha-1 along with nitrogen addition based on leaf colour chart critical value less than 4. Application of vermicompost @ 2.5 t ha-1 along with nitrogen addition based on leaf colour chart critical value less than 4 was registered highest benefit cost ratio of 2.14 when compared to control was 1.83.</div>
