Effect of different quantities of NPK and plant spacing on plant growth, yield and quality of chilli (Capsicum annum L.)

A present investigation was carried out at the central research farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh during Rabi season, 2023-24 with a view to identify the effects of different level of NPK and its role in growth, yield and quality of Chilli variety Ghoomar F1. The experiment was laid in the randomized block design with 3 replications and 10 treatment. Different quantities of fertilizer used of NPK(120:80:80) recommended and I increased the quantity N:P:K 15:15:15 kg/ha, N:P;:K 20:20:20 kg/ha and N:P:K 25:25:25 kg/ha. From the above experimental finding it may be concluded that the treatment (T8) N:P:K 25:25:25 kg/ha and spacing (60x45 cm).was found to be best in the terms of growth, plant height, days to first flowering, days to 50% flowering, number of fruits per plant and in terms of yield, average fruit weight, Yield per Hectare and in terms of quality, TSS and Ascorbic acid.
