Effect of foliar spray of plant growth regulators on the growth and yield of cauliflower (Brassica oleracea var. botrytis L.) cv. pant Shubhra

Abstract

The experiment was carried out with RBD with ten treatments and three replications. All treatments exhibited superior growth and yield of curd. Treatment T2 found highly effective for growth parameter as it showed greatest plant height (61.80 cm), no. of leaves per plant (23.80), stem length (20.40 cm), leaf length (45 cm) and leaf width (31 cm) while the treatments T10, T8 and T6 recorded highest stem diameter (10 cm), leaf width (31.33 cm) and root length (24.40 cm) respectively. The treatment T6 found highly effective for yield attributing characters as it recorded highest curd diameter (46.20 cm), curd weight (668 gm) while the treatments T8 and T9 showed second position respectively. Therefore the treatments T6, T2, T8, and T10 found highly effective as it improves vegetative growth, yield and nutritional quality of crop.
