Abstract/ Executive Summary:

Response of cauliflower to polyethylene mulch was evaluated during September ’03 to January ’04 at Regional Agricultural Research Station (RARS), Ishurdi, Pabna to find out whether black polyethylene mulch is suitable or not for cauliflower production in Bangladesh. The treatments were polyethylene mulch (with or without) and the three varieties (Poushali, Snow crown and IPSA-1). There was a positive impact of mulch on yield and yield attributes of the crops. The highest marketable yield (31.32t/ha) was obtained from hybrid variety Snow crown with mulch was 35.16% higher than without mulch. Other two varieties also produced higher yield under mulched condition than the without mulch. The production cost was higher in mulched treatment by Tk. 1510. A net additional return of Tk. 97800, 41040 and 30840 from the varieties Snow crown, Poushali and IPSA-1 respectively, was obtained due to mulching.

Start Date: 00-09-2003

End Date: 25-01-2004

Program Area: Crop-Soil-Water Management

Commodity: Cauliflower

Objectives:

To find out whether black polyethylene mulch is suitable or not for cauliflower production in Bangladesh.

Methodology:

An experiment was conducted during the September’03 to Jamuary’04 at RARS, Ishurdi, Pabna. Three variety of cauliflower IPSA-1, Poushali and Snow crown were used in this study with mulch and no mulch. The experimental design was Randomized Complete Block Design with 3 replications. The plot size was 9 m x 1.2 m Fertilizer application was done @ cowdung 10000, Ash 500, N 120, P₂0₅ 80 and K20 100 kg/ha. The entire quantity of cowdung, Urea (N), TSP (P₂0₅), MP (K₂0) and half of ash were applied as basal dose during land preparation. The remaining ash was applied in the pit. In the mulch designated plots, polyethylene mulch was placed on the day of planting. Transplanting holes on the polyethylene mulch were made with a blade at the transplanting spot for each seedling. Then transplanting pits were dug and ash was mixed with the soil of the pit. Healthy, uniform sized thirty days old seedlings were transplanted in the pit on 8 October, 2003 at the spacing of 60 x 60 cm. Each plot had two rows of 15 plants. Irrigation and weeding were done properly when needed. Curds were harvested at mature stage. Harvesting was started from December 23, 2003 and was completed by January 25, 2004. Data on plant height, no. of leaves/plant at 50 days after transplanting (DAT), biggest leaf size at 50 DAT, curd diameter, curd height, pure curd yield and marketable curd yield were recorded timely. Economic analysis of this experiment was also done. The cost of production for land preparation, seed transplanting materials, mulch, weeding, fertilizer, irrigation and man hours (mh) required for all operations including harvesting were recorded plot wise. The market price of cauliflower was determined at harvest.

Achievement/Findings:

Higher net return can be obtained by using mulch than the traditional method of growing cauliflower without any mulch. The cultivation of the variety Snow crown is more profitable than the variety Poushali and IPSA-1.
