Influence of inorganic fertilizers on yield and quality of broccoli (brassica oleracea var. italic a l)

Abstract

Abstract : Experiments in field and laboratory of Horticulture Department of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, were conducted during 10 October 2007 to 28th February 2008, to study the growth, yield and quality of broccoli under different fertilizer treatment combinations. There were 13 treatments in the experiment comprising four levels each of N, P, K and Mo. The highest plant height (60.67 cm) and the maximum leaves/plant (14.67) were found in T4 (N|35P30K50M003) treatment. The highest yield (16.67 t/ha) was obtained from T4 which was statistically similar with T7 (NOP00K50MO0.3) (15.29 t/ha). Dry matter content was the maximum (9.44%) in T, (N0P0K0M00) and the minimum (7.47%) in T4. The highest ascorbic acid content (33.04 mg/100 g) and 0-carotene (0.49 mg/100 g) were recorded in T, (control) where no fertilizer was applied, but the minimum value was noted in T4 (Nl3sP3oK5oMo0.3)'
