Effect of Different Form of Phosphorous Nutrition on Growth and Yield of Cauliflower (Brassica Olaracea Var. Botrytis L.)
Abstract: A field experiment was conducted at Naggar Farm of I.A.R.I., Regional Station Katrain, (Kullu Valley) H.P. during 2005-06 and 2006- 07 with cauliflower var. Pusa Snowball K-1. The experiment was laid out laid out in a randomized block design with 3 replications. There were ten treatments comprising of different sources of phosphorous. These were T-1 100% phosphorous ( Single Super Phosphate), T-2 100% Phosphorous (Rock Phosphate), T-3 50% phosphorous (Rock Phosphate) + Psolubiliser + Vascular Arbuscular Mycorrhizal (VAM), T-4 VAM, T-5 P solubiliser, T-6 100% Phosphorous (Rock Phosphate) + 15 t/ha Farm Yard Mannure, T-7 Liming + 50% phosphorous(Single Super Phosphate), T-8 15 t/ha Pine needle compost, T-9 15 t/ha Rice straw compost and T-10 control. The maximum curd yield were recorded with 50% P (R.P.) + P solubiliser + VAM (415.30 q/ha) followed by liming + 50% P (SSP 387.22 q/ha) and maximum growth were recorded with 50% P (R.P.) + P solubiliser + VAM 1339.73 cm2)followed by 100% P (R.P.) + 15t/ha FYM (1097.57 cm2).
