EFFECT OF BORON ON YIELD AND QUALITY OF BROCCOLI GENOTYPES (Pages : 1 - 7)

A field experiment consisting 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 to find out the suitable dose(s) of boron and genotype for higher yield and good quality head in the climatic condition of Bangladesh. Maximum ?-carotene and dry matter content of main curd were noted in the genotype Green Calabrese. Whereas maximum dry matter content of secondary curd, ascorbic acid, iron and calcium content were measured in genotype Late Calabrese. Premium Crop produced minimum number of hollow stem plant per plot. Early Green performed the best regarding highest potassium content, yield per plant (681.1 g) and total yield (27.24 t/ha). Result revealed that, there was a significant and positive effect of boron application on the yield and quality of broccoli and 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. Dry matter, ascorbic acid, and potassium content were increased with the increase of boron level up to 2.0 kg/ha and then declined with further increase of boron. On the other hand, iron and ?-carotene content increases with the increase of boron level up to 3.0 kg/ha. Calcium content was found to be decreased with the increase of boron level.Download
