Abstract: The study was carried out on clayey in texture soil at College Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari to study the “influence of integrated nitrogen management in summer maize (Zea mays L.) Under south Gujarat condition. The soil was slightly alkline in soil reaction (7.98), low in available nitrogen (230kg/ha), medium in available phosphorus (38 kg/ha) and fairly rich in potassium (379 kg/ ha). Eight treatments comprising of inorganic and organic sources of nutrients compared with chemical fertilizers alone and these treatments were tried in Randomized Block Design with three replications. Significantly higher grain and straw yield (4032 and 6039kg/ha, respectively) of maize were recorded under 100% recommended dose of nitrogen through inorganic fertilizer, which were at par with 75% RDN through inorganic fertilizer + 25% RDN from vermicompost, 75% RDN through inorganic fertilizer + 25% RDN from biocompost, 50% RDN from inorganic fertilizer + 50% RDN from vermicompost. Further, it was noticed that the different integrated nitrogen management, 75% RDN through inorganic fertilizer + 25% RDN from vermicompost recorded significantly higher grain and straw yield. The increase in available nitrogen, phosphorus and potassium were significantly higher with the application of 1/3 RDN from inorganic source + 1/3 RDN from biocompost +1/3 RDN from vermicompost. The maximum net realization of 55308 /ha with BCR 2.37 recorded with 100% RDN though urea followed by treatment 75% RDN through urea + 25% RDN though biocompost.
