Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 3
Abstract
An experiment was conducted during kharif 2013 and rabi 2013-14 at College of Agriculture, College farm, Rajendranagar, Hyderabad to evaluate the best combination of organic and inorganic sources of nutrients for maximizing yield and profitability. Combined application of poultry manure 5 t ha-1 + 75% recommended dose of NPK recorded higher fruit yield (33.6 t ha-1) and curd yield (29.3 t ha-1) followed by combining application of sewage sludge 5 t ha-1 + 75% recommended dose of NPK. The highest benefit: cost ratio obtained in treatment with sewage sludge 5.0 t ha-1 + 75 per cent RDF for brinjal (2.14) and cumulative sewage sludge applied 5.0 t ha-1 + 75 per cent RDF for cauliflower crop (2.40). Pooled data of economic analysis indicated that the highest B: C ratio (2.27) was obtained with sewage sludge 5.0 t ha-1 + 75 % RDF.
