Abstract/ Executive Summary:

The experiment was conducted at East Killarchar, Amanatgonj, Thanarhat, Hazirhat and Dhormapur under Companigong, Subornachar and Noakhali Sadar Upazillas of Noakhali district during rabi season of 2011-2012. The objective was to observe the performance of chilli + garlic inter cropping in the saline coastal areas. There were six treatments viz., Sole chilli (local), Sole garlic (local), Chilli + local garlic, Chilli + BARI Rashun 1 (20%), Chilli + BARI Rashun 2 (20%), Chilli + BARI Rashun 1 (40%) and Chilli + BARI Rashun 2 (40%). Chilli equivalent yield was found highest in Chilli + 40% BARI Rashun 2 (2.51 t ha^-1) inter cropping followed by Chilli + 40 % BARI Rashun 1 (2.39 t ha^-1). Higher LER was recorded in Chilli + 40% BARI Rashun 2 (1.27) followed by Chilli + 40 % BARl Rashun 1 (1.20) Land advantages of the crop combination were found to vary from 20 to 27%. Higher net return (Tk 261850/ha) was obtained from the treatment Chilli + 40 % BARI Rashun 2, which was followed by Chilli + 40% BARI Rashun 1 (Tk 245750/ha). Chilli + garlic inter cropping showed higher BCR (3.59 to 3.96) over sole chilli and garlic (2.74 and 2.27, respectively).

Keywords: Chilli, Garlic, Intercropping System, Coastal Saline Area

Location: East Killar Char under Companigong upazilla, Amanatgonj and Thanarhat under Subornachar upazilla and Hazirhat and Dharmapur under Noakhali Sadar Upazilla.

Start Date: 00-00-2011

End Date: 00-00-2012

Program Area: Farming System

Commodity: Garlic, Chilli

Objectives:

To observe the performance chilli + garlic inter cropping in the saline coastal area.

Methodology:

The experiment was conducted in the East Killar Char under Companigong upazilla, Amanatgonj and Thanarhat under Subornachar upazilla and Hazirhat and Dharmapur under Noakhali Sadar Upazilla during rabi season of 2011-2012. Sole chilli (local), Sole garlic (local), Chilli + BARI Rashun 1 (20%), Chilli + BARI Rashun 2 (20%), Chilli + BARI Rashun 1 (40%) and Chilli 1 BARI Rashun 2 (40%) were tested at six dispersed locations in the farmers' field. The land area was about half bigha per farmer. 20% garlic population means one row of garlic in between two rows of chilli and 40% garlic means two rows of garlic in between two rows of chilli. The land was fertilized with 10 t/ha of decomposed cow dung and inorganic fertilizer @ 93-35-125-18 kg NPKS/ha (FRG, 2005). All of cow dung, P, S, half of MoP and 1/3 urea were applied at the time of final land preparation. Remaining MoP and Urea were applied in two equal installments at 20 and 40 days after transplantation and sowing. The experiment was established during 5 - 21 December 2011. The crops were irrigated twice with jar. Weeding and other intercultural operations were done as and when needed. A systematic insecticide (Cypermethene) was sprayed at seedling stage to control aphids and thrips. Garlic was harvested during 22 March to 5 April 2012 and chilli was harvested during 25 March to 15 May 2012. Mean yield data from six farmers' fields were recorded and analyzed statistically. Gross return and variable cost were calculated considering the prices of chilli seedlings: Tk. 50.00/1000 seedlings, local garlic seed: Tk. 50.00/kg, BARI Rashun 1 & 2 seed: Tk. 70.00/kg, urea: Tk. 20.00/kg, TSP: Tk. 22.00/kg, MoP: Tk. 15.00/kg and gypsum: Tk. 12.00/kg. The other variable costs were for land preparation, transplanting. dibbling, weeding, insecticide, irrigation and harvesting costs. Chilli selling price was Tk 140.00/kg (dry) and garlic price was Tk. 35.00/kg for all varieties.
