EFFECT OF BORONATED SULPHUR ON THE GROWTH AND YIELD OF CAULIFLOWER

D. Panda and S. Mondal

Abstract

A field experiment was conducted at Agriculture Farm of Institute of Agriculture, Visva-Bharati University, Sriniketan to study the effect of different levels of Boronated Sulphur on cauliflower during Rabi season of 2018-19. The growth and yield parameters of cauliflower were recorded at 40 and 60 DAT. The experimental finding revealed that fertilization with Boronated Sulphur (7.5 kg/ha, 10 kg/acre, 15kg/ha and 20kg/ha) significantly increased the growth parameters such as plant height and number of leaves per plant both at 40 and 60 DAT, whereas significantly reduced the days required to curd initiation and curd maturity. However, application of 10kg/ha of Boronated sulphur significantly increased the yield parameters of cauliflower such as curd wt./plant and curd yield/ha. The ascorbic acid content of the curds was found to be significantly higher from treatments of Boronated Sulphur T3 (10 kg/acre) and T4 (15kg/acre). However, T3 (10 kg/acre of Boronated Sulphur) was the best treatment in terms of growth as well as yield parameters of cauliflower such as plant height (21.77cm), number of leaves per plant (18.17), stem diameter (2.34 cm), curd initiation (65.2 days), curd maturity (67.2 days), curd weight (726.83g), fresh curd yield (17.44 t/ha), vitamin C (41.47 mg/l00g) and physiological parameters such as chlorophyll a (2.102 mg/g), chlorophyll b (0.869 mg/g), total chlorophyll (2.970 mg/g) and carotenoids (0.344 mg/g) content and relative leaf water content (82.3%).
