Effect of Organic Manures and Inorganic Fertilizers on Growth, Yield and Quality of Onion (Allium cepa) var. Nashik Red

An experiment was conducted to find out the effect of organic manures and inorganic fertilizers on growth, yield and quality of onion (Allium cepa L.) var. Nashik Red during 2021-2022 in Rabi season (Nov-Apr) at Horticulture Research Farm, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad (Uttar Pradesh). Total 13 treatments were replicated thrice in Randomized Block Design (RBD). The results showed that treatment T4 (75% NPK + 25% Poultry manure) was recorded maximum in growth and quality parameters i.e., plant height (62.29 cm), maximum number of leaves (10.38), maximum TSS (14.58 0Brix) and maximum ascorbic content of (12.49).whereas, the yield parameters were maximum in treatment T8 (50% NPK + 50% Poultry manure) was recorded with maximum weight of fresh bulb weight (181.70 g), maximum weight of cured bulb (168.07 g), maximum bulb diameter (8.63 cm), maximum yield per plot (23.09 kg) and maximum yield per hectare (15.36 t).
