Effect of integrated nutrient management on growth, economics and yield attributes of broccoli (Brassica oleracea L. var. italica Plenck) cv. Pusa broccoli KTS-1 under Dehradun condition of Uttarakhand

Abstract

Present investigation was undertaken to study the response of integrated nutrient management on growth, yield and economics of broccoli cv. Pusa Broccoli KTS-1. For this, a field experiment was carried out in Randomized Block Design with three replications. The experiment was conducted at the Horticulture Research Block of Shri Guru Ram Rai School of Agricultural Sciences, during rabi season of 2017-18. For the experiment, nine treatment combinations are taken viz. Full dose of NPK through chemical fertilizer (T1), FYM@ 25t/ha (T2), FYM @15t/ha + half NPK through fertilizer (T3), Neem Cake @5q/ha (T4), Neem Cake @ 2.5q/ha + half NPK through fertilizer (T5), Vermicompost @5t/ha (T6), Vermicompost @2.5t/ha + half NPK through fertilizer (T7), Poultry manure @ 5t/ha (T8), Poultry manure @ 2.5t/ha + half NPK through fertilizer (T9). The cultivar Pusa Broccoli KTS-1 of broccoli was transplanted at a spacing of 50cm x 50cm. Results indicate that the treatment combination of Vermicompost @2.5t/ha + half NPK through fertilizer (T7) recorded maximum head length (14.88 cm), head width (13.68cm), gross head weight (368.22 g), net head weight (296.85g), yield per plot (13.26kg), net yield (164.66 q/ha) and benefit:cost ratio (3.98) followed by treatment T9 (Poultry manure @ 2.5t/ha + half NPK through fertilizer) and (T1) Full dose of NPK through chemical fertilizer.
