Abstract:
An investigation was carried out at the vegetable research farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during rainy season of 2018 and 2019. The soil of the experimental field was sandy-loam with uniform topography. A field experiment was conducted to determine the N, P and K rates for yield attributes i.e. total yield, diameter of bulb, double bulb, bolting percentage neck thickness and T.S.S. as quality parameters of onion. A factorial combination of three rates of N (50,100 &50 kg /ha), two rates of P (40 & 80 kg/ ha) and potash two level (50 &100 Kg/ha) were used for the experiment. Treatments were laid down in a Randomized Complete Block Design (RCBD) in a factorial combination with three replications. Two years trial with Cv. Agrifound Dark Red and results of this study revealed that the application of nitrogen showed significant effect in most of studied characters. Higher levels of nitrogen increased the yield significantly over all the treatments. Different levels of phosphorus and potassium did not affect the quality parameters of onion. Phosphorus and potassium did not show any significant alteration on yield and yield attributes and quality. The application of 150 kg N +80 kg P2O5 +100 Kg K2O/ ha was most appropriate combination of nutrients with respect to yield and quality of the rainy season onion crop propagated through seedling.
