CONTRIBUTION OF BORON DOSES ON GROWTH AND YIELD OF DIFFERENT BROCCOLI GENOTYPES (Pages : 14 - 20)

A field experiment comprising of four broccoli genotypes (G1= Premium Crop, G2= Early Green, G3= Green Calabrese and G4= Late Calabrese) with four different levels of boron (L1= control or without boron, L2= 1 kg/ha, L3= 2 kg/ha and L4= 3 kg/ha) was conducted at the experimental field of Department of Horticulture, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur during the winter (Rabi) season of 2012-13. Early Green performed the best regarding head diameter (19.04 cm), yield per plant (681.1 g) and total yield (27.24 t/ha). There was a significant and positive effect of boron application on the yield of broccoli. Control (without boron) treatment required highest days (48.92) for curd initiation but minimum days (61.75) for curd harvest. But L3= 2 kg/ha treatment showed the opposite result. Result of maximum parameter revealed that, 2.0 kg B/ha was found to be an optimum rate. The genotype Early Green yielded the highest (32.19 t/ha) when boron was applied @ 2 kg/ha. Download
