Economics, fertility status and microbial count on soil of onion (Allium cepa L.) cv. GJRO-11 as influenced by organic, inorganic and biofertilizer

Present investigation was conducted the year 2018-19 in Rabi season at Horticultural Research Farm, College of Horticulture, AAU, Anand, Gujarat with ten treatments in a simple RBD with three replications. The soil application of 50 % RDF + 50 % N from FYM was significantly maximum avaibility of N, P2O5, K2O and Organic carbon (369, 44.67, 331 kg/ha and 0.39 %, respectively) and application of 50 % RDF + 25 % N through FYM + 5 ml Bio-NPK consortium recorded maximum Azotobacter, Azopirillum, PSB, KMB and Total count of bacteria. Among the different treatments; T9- 50% RDF (50: 37.5: 37.5 NPK kg/ha) + 25% N from vermicompost + 5 ml Bio-NPK consortium registered the highest net realization 306569.38`/ha with BCR value of 3.35 as compared to rest of the treatments.
