EFFECT OF BORON AND MOLYBDENUM ON GROWTH AND YIELD OF CAULIFLOWER

Abstract

The field experiment was conducted to investigate the effect of boron and molybdenum on growth and yield of cauliflower at the Horticulture Farm of Shere-Bangla Agricultural University, Dhaka. The experiment consisted of two

factors

such

as Factor A: Boron (4 levels) as B 0 X : 0 (Control) B 1 : 0.5 kg/ha, B 2 :1 kg/ha, B 3 :1.5 kg/ha and Factor B: Molybdenum (4 levels) as Mo0: 0 (Control) Mo 1 :0.25 kg/ha, Mo 2 : 0.50 kg/ha, Mo 3 : 0.75 kg/ha. There were 16 treatment combinations and laid out in Randomized Complete Block Design (RCBD) with three replications. The influence of different levels of boron, molybdenum and their combined effect showed significant variations in growth and yield of cauliflower. In case of boron, the highest plant height (56.53 cm), number of leaf (21.59), leaf length (43.98 cm), leaf breadth (21.20 cm), stem diameter (2.13 cm), curd diameter (14.51 cm), curd fresh wt. (637.25 g), dry matter % of curd (10.11), yield/plot (5.09 kg) and yield/ha (26.55 ton) were obtained from B 2 (1 kg B/ha). For molybdenum, Mo 2 (0.50 kg Mo/ha) produced the highest plant height (55.75 cm), number of leaf (21.01), leaf length (43.73 cm), leaf breadth (20.95 cm), stem diameter (2.17 cm), curd diameter (14.46 cm), curd fresh wt. (656.22 g), dry matter % of curd (10.60), yield/plot (5.24 kg) and yield/ha (27.34 ton). In combine treatments, the maximum plant height, number of leaves, leaf breadth, curd fresh weight, dry matter % of curd was produced from the treatment combination of B 2 (1 kg B/ha) with Mo 2 (0.50 kg Mo/ha). However, treatment combination of B 2 Mo 2 (1 kg B/ha with 0.5 kg Mo/ha) performed the best results. So, 1 kg Boron/ha with 0.5 kg Molybdenum may use for cauliflower cultivation.
