Abstract/ Executive Summary:

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 M1: soil test based (STB) recommended fertilizer and M2: fertilizer dose practiced by the farmers (FP) and the level of limes were L1:0 t ha^-1; L2: 1 t ha^-1 and L3: 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 (M1-N₂₀₁, P₆₃, K₆₅, S₂₃, Zn_0.5 for cabbage and M1-N₁₅₇, P₅₇, K₁₁₆, S₂₀, 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 (L3) provided the highest yields of cabbage and cauliflower in all locations. Dolomite lime @ 2 t ha^-1 in combination with recommended fertilizer (M1L3) 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 (M1) could be enough for profitable economic returns for cultivating cabbage and cauliflower in strongly acidic soil in Sylhet.

Objectives:

To find out the suitable levels of dolomite lime and fertilizer management options for better yield of cabbage and cauliflower in acidic soils under the AEZ 20 of Sylhet region

Methodology:

An experiment was conducted under farmer’s fields located at FSRD site, Jalalpur and MLT sites, Moulvibazar and Zokigonj during 2013-2015 to study the effect of lime and fertilizer on the yield of cabbage and cauliflower in acidic soil of Sylhet. The study area lays 24⁰70' N latitude and 91⁰67' E longitude under the Surma-Kusiyara Floodplain of Bangladesh. Before starting the experiment, initial soil samples were collected from each farmer’s field and analyzed in the laboratory of Soil Resource and Development Institute, Sylhet.

Type of experimental soil is non-calcareous grey with low organic matter content (1.29%), low soil pH (4.2-5.1), very low total N (0.06%), low content of P (8.59µg/g soil), K (0.13meq/100g soil) and S (9.14 µg/g soil) where as Zn (1.22 µg/g soil) and B (0.48 µg/g soil) medium and optimum, respectively. Trials were laid out in a factorial randomized block design with six dispersed replications where 2 fertilizer managements levels were M_1- soil test based (STB) recommended fertilizer and M_2- Fertilizer dose practiced by the farmers (FP) and 3 level of limes viz., L_1- 0 t ha^-1, L₂- 1 t ha^-1 and L₃- 2 t ha^-1 as treatment variables. The dolomite lime (CaO = 30 %, MgO = 22% and CO₂= 48%) was applied 15-20 days before planting with spread method on the top of the soil and then incorporate with the soil depth at 25 cm by plough. The crops wise fertilizers nutrients N P K S Zn (cabbage - M₁: 201-63-65- 23-0.5, M₂: 220-70-70-40-0 and cauliflower - M₁: 157-57-116-20-0.5, M₂: 170-43-136-0-0 Kg ha^-1) were calculated as per the initial nutrient status of the experimental soil and average fertilizer doses practiced by 25 farmers. Fertilizers were applied in the form of Urea, TSP, MoP, Gypsum and Zinc sulphate, respectively. Half of urea and all other fertilizers were applied and mixed with soil at the time of final land preparation. Rest urea was top dressed at 25 days after transplanting. Seedlings of cabbage (var. Atlas-70) and cauliflower (var. Canditcharm) at the age of 30 days were planted on a plot size of 5 m x 4 m with plant spacing of 60 cm x 40 cm. The crops were harvested 80-95 days after planting (DAP). Twice irrigations one of each at 25 days interval from the transplant of seedlings; one weeding at 20 DAP; two sprayings of secure fungicide @ 1.5mL^-1 of water for controlling blight of crops. All intercultural operations were done as when necessary. The head and curd yield of cabbage and cauliflower were recorded from 10 randomly selected plants from each plot and yield of crops were recorded from whole plot basis at harvest. The recorded data were statistically analyzed and mean values were separated by least significant difference test (LSD). All types of variable costs of production were recorded and cost-benefit analysis was carried out (Heady and Dhillon, 1988).

Achievement/Findings:

The results revealed that the maximum head yield of cabbage and curd yield of cauliflower was obtained with the application of STB recommended fertilizer (N₂₀₁, P₆₃, K₆₅, S₂₃, Zn_0.5 for cabbage and N₁₅₇, P₅₇, K₁₁₆, S₂₀, Zn_0.5 Kg ha^-1 for cauliflower). Liming at the rate 2 t ha^-1 supported for the highest yields of cabbage and cauliflower in both the years in all the locations but identical to that of 1 t ha^-1of dolomite lime with similar dose of fertilizers Therefore, application of lime at the rate 1 t ha^-1 with recommended fertilizer might be effective for economic productivity of both the cabbage and cauliflower in the acidic soils of the greater Sylhet region.
