Abstract
The present investigation was carried out at the Research Farm of the Department of Vegetable Science and in the laboratories of the Department of Soil Science and Vegetable Science, CCS Haryana Agricultural University, Hisar, Haryana during the summer season of 2019-20 to evaluate the effect of integrated nutrient management on the growth, yield and quality of chilli and the Seed of chilli cv. “Kashi Anmol” was grown with thirteen different treatment combinations. All the treatments were assessed for the growth, yield and quality parameters. The experimental results revealed that the application of Recommended NPK + Vermicompost @ 2 t/ha + Azotobacter (T3) followed by treatment T5 (50 % NPK + FYM @ 12.5 t/ha + Vermicompost @ 2 t/ha + Azotobacter) and T4 (Recommended NPK + FYM @ 12.5 t/ ha + Azotobacter) performed superiorly over the other treatments with remarkably higher values for all the growth yield and quality attributes viz., plant height (cm), number of primary branches, days to first fruit harvest, average fruit weight (cm), yield per plot and per hectare, ascorbic acid (mg/100g), total soluble solids (%) and NPK uptake by the plant (g/plant). During the investigation the net returns and benefit cost ratio was also found highest in these treatments. However, minimum values for these attributes were recorded under control (T13). Therefore, to reduce the cost of chemical fertilizers with maintaining sustainability of soil fertility and for higher yield and benefit-cost ratio the chilli crop may be supplied with 50 % Recommended NPK + FYM @ 12.5 t/ha + Vermicompost @ 2 t/ha + Azotobacter as per treatment (T5).
