Study on the Effect of Integrated Nutrient Management (INM) on Yield and Quality in Cauliflower (Brassica oleracea var. botrytis L.)

Abstract

With the purpose to investigate the effect of integrated nutrient management (INM) on yield in Cauliflower, Brassica oleracea var. botrytis L., cv. Sabour Agrim, research was conducted using Randomized Block Design with 9 treatments replicated thrice from March 2021 to May 2021. The trial comprised of 9 different treatment combinations consisting varied sources of nutrients including in-organic, organic and bio-fertilizers. The yield parameters like gross curd weight (0.96 kg), marketable curd weight (535 g), yield per plot (13.36 kg) and yield per hectare (26.74 tonnes) were observed maximum in treatment 75%RDF+12.5%FYM+12.5%Vermicompost+Bio-fertilizer (Azotobacter+PSB) (T6). Similar results were obtained for quality parameters like curd depth (9.09 cm), curd size (322.00 cm2) and curd solidity (58.81 g/cm). From the studies it was inferred that the application of 75%RDF+12.5%FYM+12.5%Vermicompost+Bio-fertilizer (Azotobacter+PSB) was supposed to be the most effective treatment combination for boosted yield and quality in cauliflower.
