摘要:An experiment was conducted at farming system research and development (FSRD) site, Jalalpur and multi location testing (MLT) sites, Moulvibazar and Zokigonj during 2013-2015 to study the effect of liming and fertilizers levels on the yield of cabbage and cauliflower in acidic soil of Sylhet. Trials were laid out in a factorial randomized block design with six dispersed replications. The treatments of fertilizer managements were M 1 : soil test based (STB) recommended fertilizer and M 2 : fertilizer dose practiced by the farmers (FP) and the level of limes were L 1 :0 t ha-1; L 2 : 1 t ha -1 and L 3 : 2 t ha -1 . Results revealed that yields of cabbage and cauliflower responded significantly to fertilizer doses, levels of lime, and their combinations in all the locations. Soil test based fertilizer rate (M 1 -N 201 , P 63 , K 65 , S 23 , Zn 0.5 for cabbage and M 1 -N 157 , P 57 , K 116 , S 20 , Zn 0.5 Kg ha -1 for cauliflower) gave the maximum head and curd yields of cabbage and cauliflower, respectively. The levels of lime at the rate 2 t ha -1 (L 3 ) provided the highest yields of cabbage and cauliflower in all locations. Dolomite lime @ 2 t ha -1 in combination with recommended fertilizer (M 1 L 3 ) gave the highest yields and maximum economic returns of cabbage and cauliflower in all locations. However, it was identical with 1 t ha -1 of dolomite lime of similar dose of fertilizer nutrients. Therefore, application of lime at the rate 1 t ha -1 with STB recommended fertilizer management (M 1 ) could be enough for profitable economic returns for cultivating cabbage and cauliflower in strongly acidic soil in Sylhet.
