Effect of organic, inorganic and biofertilizer on growth and yield of onion (Allium cepa L.) cv. GJRO-11

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: 37.5: 37.5 NPK kg/ha) + 25% N from vermicompost + 5 ml Bio-NPK consortium was most effective treatment and which was recorded significantly maximum on growth and yield parameters viz., plant height (70.11 and 86.70 cm at 45 and 90 DAT respectively), minimum bolting per cent (4.38), average bulb weight (129.30 g), bulb volume (136.70 cc), neck thickness (1.11 cm), bulb yield (24.18 kg/plot and 497.60 q/ha), maximum A and B grade bulb yield (395.98 q/ha and 91.50 q/ha, respectively) and TSS (13.47 oBrix). While number of leaves per plant was non-significant.
