Study the Effect of Integrated Nutrient Management on Growth and Yield of Cauliflower

Abstract— A field experiment entitled “Effect of Integrated Nutrient Management on Growth and Yield of Cauliflower (Brassica oleracea var. Botrytis L.)” was conducted at Research Farm, Himalayan Garhwal University, Uttarakhand during Rabi season of 2020-21. The experiment was laid out in factorial randomized block design with three replications and consisting four fertility levels (Control, 50% RDF, 75% RDF and 125% RDF) and three treatments of organic manure (control, FYM @ 20 t/ha + Azospirillum and vermicompost @ 7.5 t/ha + Azospirillum). Results showed that application of 100% RDF significantly increased the plant height, number of leaves per plant, plant spread, days taken to curd maturity, biological yield, curd diameter, fresh weight of curd, curd yield, nitrogen, phosphorus and potassium content, net returns and B: C ratio of cauliflower which was superior as compared to control and 50% RDF.
