INFLUENCE OF BORON ON GROWTH AND YIELD OF BROCCOLI CULTIVARS

Abstract

A field experiment comprising of three broccoli cultivars (V 2  Green Magic and V  BARI Broccoli-1) with four different levels of boron (B 0  control, B 1 3  1 kg/ha, B 2   3 kg/ha) was conducted at Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, during October, 2015 to February, 2016. The experiment was laid out in Randomized Complete Block Design with three replications. The significant variation was observed among the cultivars in different parameters. Green magic performed the highest yield (16.48 t/ha) and the lowest yield (13.38 t/ha) was found from BARI Broccoli-1. 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 cultivars and boron.

2 kg/ha and B

3 The highest yield (17.12 t/ha) was found from the treatment B and the lowest (13.14 t/ha) from the treatment B 0 .

2 For combined effect highest yield (18.16 t/ha) was found from V and lowest (12.45 t/ha) was obtained from V 3 B The highest benefit cost ratio was found in V 2 B 2. 0. So, Green magic cultivar with 2 kg boron was found suitable for growth and yield of broccoli.
