EFFECT OF BORON AND MOLYBDENUM ON GROWTH AND YIELD OF BROCCOLI

Abstract

An experiment was conducted at Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during October 2019 to February 2020 to study the effect of boron and molybdenum on growth and yield of broccoli. The experiment comprising of two factors, factor A: four levels of boron [B0=0kg/ha, B1=0.6kg/ha, B2=1.2kg/ha and B3=1.8 kg/ha] and factor B: four levels of molybdenum [M0=0kg/ha, M1=0.4kg/ha, M2=0.8kg/ha and M3=1.2 kg/ha]. The experiment was laid out in Randomized Complete Block Design with three replications. The significant differences were found in growth and yield contributing traits. Most of the parameters such as no. of leaves, leaf breadth, root length, main curd diameter and main curd weight were significantly influenced by the different boron and molybdenum dose. The highest yield (16.70t/ha) was found in the treatment B2 and the lowest (10.65 t/ha) from the treatment B0 and in case of molybdenum, the highest yield (16.09 t/ha) was recorded in M2 and the lowest yield (12.21 t/ha) recorded in M0. For combined effect highest yield (20.55 t/ha) was found from B2M2 and lowest (8.98 t/ha) was obtained from B0M0. The highest benefit cost ratio (2.65) was found in B2M2. So, the successful production of broccoli was found in combined application of 1.2 kg boron with 0.8 kg molybdenum per hectare.
