Abstract:

A field experiment was conducted at South Surma upazila of Sylhet district to evaluate the effect of vermicompost, cowdung and inorganic fertilizers on the growth and yield of cauliflower (Brassica oleracea var. botrytis L.) in acid soil. The experiment comprised of four treatments viz. T1 = 135-60-135-21-3-1.5 kg ha-1 of N-P-K-S-Zn-B, T2 = T1 + Cowdung (5 t ha-1), T3 = T1 + Vermicompost (5 t ha-1) and T4 = Vermicompost (10 t ha-1). The experiment was laid out in a randomized complete block design with three replications. The results on growth parameters recorded at 15, 30 and 45 DAT showed significant variation in different growth and yield contributing characters. The tallest plant (24.47 cm) was recorded at 45 DAT in T3 treatment. The same treatment at 30 DAT produced the highest number of leaves plant-1 (8.33) while T4 had the lowest number of leaves plant-1 (5.93). The longest length and breadth of the largest leaf and spreading of plants were recorded 19.60, 10.03 and 16.53 cm at 45 DAT in T3, respectively. The highest curd yield (29.72 t ha-1) was recorded in T3 treatment. Post-harvest soil analysis showed higher amount of organic matter, total N, available P, exchangeable K and available S contents than in initial soil. This might be due to residual effect of vermicompost. The results revealed that vermicompost addition with recommended dose of chemical fertilizers T3 performed better compared to only inorganic fertilizers.
