Nutritional Variation of Cauliflower Grown in Different Fertilizer Combinations in Soil

An experiment was conducted at experimental field and laboratory of the Soil Science Division, Bangladesh Agricultural Research Institute, Bangladesh during the period from October 2008 to March 2009 to evaluate the variation in nutritional contents of cauliflower to different fertilizer combinations. Experiment consisted twelve treatments, viz., T1: 100% Recommended Dose of Chemical Fertilizer (RDCF; RDCF= N250P35K65S40 Zn5B1 kgha-1); T2: 80% RDCF; T3: 60% RDCF; T4: 100% RDCF+Vermicompost @ 1.5 tha-1; T5: 80% RDCF+Vermicompost @ 3 tha-1; T6: 60% RDCF+Vermicompost @ 6 tha-1; T7: Vermicompost @ 6 tha-1; T8: 100% RDCF+Conventional compost @ 1.5 tha-1; T9: 80% RDCF+Conventional compost @ 3 tha-1; T10: 60% RDCF+Conventional compost @ 6 tha-1; T11: Conventional compost @ 6 tha-1 and T12: Control (No fertilization) following Randomized Complete Block Design with three replications. Maximum nitrogen, phosphorus, potassium, sulphur content (1.99%, 0.30%, 1.98%, 0.31% respectively on curd also 1.58%, 0.39%, 1.19%, 0.26% respectively on stover) and uptake (131.66, 13.09, 80.80, 12.50 kg/ha respectively on curd also 26.86, 6.63, 20.23, 4.42 kg/ha respectively on stover) of cauliflower were found from T4 which was statistically similar with T5. On the other hand, maximum total N (0.10%), available P (16.00 ppm), available S (15.0 ppm), available Zn (1.7 ppm) and exchangeable K (0.20 meq 100g-1 soil) were found from T5. The minimum result was observed in T12 in all of the parameters.
