Effect of Spacing, Boron and Their Combinations on Yield and Yield Attributing Characters of Cauliflower (Braccica Oleraceae Var. Botrytis L.)

Afield trial comprising of different plant spacing's and boron on the productivity of cauliflower was conducted at Vegetable Research Station (VRC), G.B.P.U & T, Pantnagar, Uttarakhand. The treatments comprised of four different plant spacing with or without boron (E₁: 60 x 50 cm without boron, E₂: 60 x 50 cm with boron, E₃: 40 x 50 cm without boron and E₅: 40 x 50 cm with boron). The result revealed significant variation in all of the parameters, amongst various plant spacing's and boron. The treatment E₁ indicated that the cauliflower yield was mostly influenced by spacing rather than boron, while the treatment E₂ influenced days to curd formation and days to 50% maturity, however, the treatments E₃ and E₄ were favourable for vegetative growth. Maximum plant weight (731.53g), curd weight (506.02 g), curd length (12.82 cm), curd breadth (6.94 cm), number of leaves (20.60), days to curd formation (99.79 days) and days to 50% maturity (129.77 days) were recorded due to the treatment E₃ where the plants were spaced 60 x 50 cm without boron.
