Abstract
A field experiment was conducted during kharif 2005 to study the effect of integrated nutrient management in maize. The results indicated that among organic manures, application of vermicompost @ 2.5 t ha-1 recorded significantly higher dry matter production in leaf, stem, cob, yield and yield attributes and uptake of nitrogen, phosphorus and potassium over control and application of residues of sorghum @ 5 t ha-1 and it was found to be on par with application of FYM @ 10 t ha-1, poultry manure @ 1 t ha-1, and incorporation of green leaf manure @ 5 t ha-1. However, application of poultry manure @ 1 t ha-1 recorded significantly higher net returns (Rs 21,045 ha-1) and B:C ratio (3.06) over control (Rs 15,176 ha-1 and 2.41 respectively). Among inorganics, application of 100 per cent RDF recorded significantly higher dry matter production in leaf, stem, cob, yield and yield attributes and uptake of nitrogen, phosphorus and potassium and also higher net returns (Rs 20,898 ha-1) and B:C ratio (2.41) over 50 per cent RDF and it was found to be on par with 75 per cent RDF.
