Study of the different organic manures and bio-fertilizers on growth and yield of cauliflower (Brassica oleracea L. var. botrytis.) Cv. Pusa Snowball - 1, under agro-climatic condition of Kanpur

Abstract

The field experiment was conducted at Agricultural Research Farm, Rama University, Kanpur, U.P. during rabi season 2023-24. The experiment was deliberated in randomized block design with eight treatments replicated thrice. Results revealed that combination of vermicompost and bio fertilizer (PSB) resulted maximum growth attributes (plant height 41.08 cm, green leaves per plant 22.08, leaf area 701.99 cm2, plant spread 36.66 cm2) and minimum time required in (flowering days 46.97 days, no. of curd initiation 79.65 days, no. of days to curd maturity 91.72 days). Yield parameters were recorded highest with combination of vermicompost and bio fertilizer (PSB) as (curd size 150.83 cm2, curd weight 981.05 gm and curd yield 246.09 q ha-1). The net return of Rs. 168285 ha-1 and B:C ratio (2.11) were recorded highest with combination of vermicompost and bio fertilizer (PSB). Combination of vermicompost and bio fertilizer (Azotobacter) proved next best treatment with respect to plant growth, yield and economics of cauliflower. The lowest values of these parameters were recorded under control.
