Effect of Organic and Inorganic Fertilizers on Growth, Yield and Quality of Broccoli (Brassica oleracea var. italica)

Abstract

The present investigation was carried out with title ‘Effect of organic and inorganic fertilizers on growth, yield and quality of broccoli (Brassica oleracea var. italica)’ at the Horticulture Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh during Rabi in 2022-23 with a view to identify the effects of different doses of organic and inorganic fertilizers and its role in growth, yield and quality of Broccoli variety Pusa KTS-1. The experiment was laid in Randomized block design with 15 treatments including control and 3 replications with different combinations of plant growth regulators. Under this experiment, overall, 15 treatments were taken including RDF (100 Kg N+80 Kg P+60 Kg K) + FYM @ 25 t . Different Organic and inorganic fertilizers were used comprised of Nitrogen, FYM, Vermicompost and Poultry manure, at different doses. According to the current research, the use of Nitrogen and various organic fertilizers had a significant positive impact on the growth and development of Broccoli. Among the various treatments that were evaluated, T7 (60% N + 13.3% FYM + 13.3% Vermicompost + 13.3% PoultryManure) best in terms of plant height (70.73 cm), number of leaves (17.27), Leaf area (33.87 cm2), days to first curd initiation (55.63 DAT), days to horticultural maturity (68.63 DAT), curd diameter (17.67 cm), curd weight (341.5g), curd yield per plot (3.07Kg), curd yield per hectare (12.64 t), TSS (11.20Brix) and ascorbic acid (105.13mg/100g).
