Abstract/ Executive Summary:

Field experiments were conducted at Multi-Location Testing (MLT) sites of Chandina and Debidwer of Cumilla district, and Kasba of Brahmanbaria district under on-farm research division (OFRD), Bangladesh Agricultural Research Institute, Cumilla during 2016-18 to find out the appropriate dose of fertilizer for the maximum productivity of hybrid cauliflower varieties. Five integrated nutrient management packages such as T₁= Recommended fertilizer dose for high yield goal (HYG), viz. 40-20-38-7-0-0 NPKSZnB Kg ha^-1, T₂= T₁ + 1.5 t ha^-1 vermicompost, T₃ = T₁ + 5 t ha^-1 cowdung, T₄= STB (107-61- 107-30-3.0-1.0 NPKSZnB Kg ha^-1 and T₅= Farmers practices (114-74-123.5-0-0 NPKSZnB Kg ha^-1) were used in the trial. The experiment was laid out in a Randomized Complete Block (RCB) design with six dispersed replications. The result revealed that the highest curd breadth (21.68 cm), individual curd weight (1.86 Kg), and curd yield (44.14 t ha^-1) was obtained from T₂ treatment followed by T₃ and T₄ treatments. The lowest yield was found from farmers' practices. Similarly, the highest gross return (Tk. 626669.00 ha^-1) and gross margin (Tk. 493869.00 ha^-1) were also found from T₂ treatment and the lowest (Tk. 457734.00 ha^-1 and 438066.00 ha^-1) respectively from farmer's practice T₅.

Program Area: Crop-Soil-Water Management

Commodity: Cauliflower, Fertilizer and manures

Objectives:

To find out an integrated fertilizer (inorganic and organic) dose for the maximum production of cauliflower.

Methodology:

The experiment was conducted at MLT sites Barura, Chandina, and Brahmanbaria under the On-Farm Research Division of Bangladesh Agricultural Research Institute, Cumilla during Rabi 2016-18 to find out the integrated fertilizer (inorganic and organic) dose for the cultivation of cauliflower. Five integrated nutrient management packages for cauliflower cultivation such as T₁= Recommended fertilizer dose for HYG (40-20-38-7-0-0 NPKSZnB Kg ha^-1 (FRG, 2012) T₂= T₁ + 1.5 t ha^-1 vermicompost, T₃ = T₁ + 5 t ha^-1 cowdung, T₄= STB (107-61-107-30-3.0-1.0 NPKSZnB Kg ha^-1 and T₅= Farmers practices (114-74-123.5-0-0 NPKSZnB Kg ha^-1) were used in the trial. The experiment was laid out in a Randomized Complete Block (RCB) design with six dispersed replications. Unit plot size was (4.0 m x 5.0 m) 20 m² and the variety Hybrid Fulkupi Atlas 777 was used. Seedlings were transplanted at the main field maintaining row to row and plant to plant distance 60 cm and 40 cm, respectively in the last week of October to the first week of November in both years. Fertilizers were applied on the basis of experimental treatments. Dolochun was applied @ 1 t ha^-1 in the whole experimental field. All intercultural and pest control measures were done as and when necessary. Harvesting of Cauliflower was done on the 2nd to 3rd weeks of January. Initial soil properties of the farmer’s field during 2017-18. Data on yield and yield parameters of cauliflower were recorded and analyzed statistically at a 5 % level of probability using the statistical program Statistix10. The cost of production was calculated on the basis of the cost of land preparation, seed cost, fertilizer cost, pesticide cost, labor cost, and land rent.

Achievement/Findings:

Based on the experimental results it was concluded that a combination of organic and chemical fertilizer package viz., 1.5 t ha^-1 vermicompost with recommended fertilizer dose for HYG had the maximum positive effect on plant growth, yield, and yield contributing characters of cauliflower. Judicious application of organic manure in combination with chemical fertilizers is essential for yield maximization of cauliflower.
