Abstract/ Executive Summary:

The experiment was conducted at ARS, Burirhat, Rangpur during rabi seasons of 2009-10 and 2010-11 to find out the suitable sowing date for bush bean cultivation. BARI Bushbean-1 and BARI Bushbean-2 were sown in 2009-10 and BARI Bushbean 1 in 2010-11. Ten sowing dates viz. 20 October, 30 October, 9 November, 19 November, 29 November, 9 December, 19 December, 29 December 8 January and 18 January were used as treatment variables in both the years. Among the sowing dates, the highest yield was recorded from early sowing (November 9-29) in both the varieties while October 20 sowing produced no pod due to severe disease infestation in both the years. The results revealed that November 9-29 would be the optimum sowing date for bush bean cultivation in North-West region of Bangladesh

Keywords: Sowing dates, Yield, Bush bean, North-West region

Location: ARS, Burirhat, Rangpur

Start Date: 20-10-2009

End Date: 20-04-2011

Program Area: Crop-Soil-Water Management

Commodity: Bush bean

Objectives:

To obtain a suitable sowing date of bush bean cultivation in North-Western region of Bangladesh.

Methodology:

The experiment was conducted at ARS, Burirhat, Rangpur during rabi season of 2009-10 and 2010-11. The experiment was carried out in RCB design with three replications. Two variety, viz. V1= BARI Bushbean-1; V2= BARI Bushbean-2 were used in 2009-10 and one variety BARI Bushbean-1 in 2010-11 and ten sowing dates viz. T1=20 Oct, T2=30 Oct, T3=9 Nov, T4=19 Nov, T5=29 Nov, T6=9 Dec, T7=19 Dec, T8=29 Dec, T9=8 Jan and T10=18 Jan were accommodated in the experiment. Fertilizers were applied at the rate of 69-96-75-20-3-1-10000 kg N-P-K-S-Zn-B-Cowdung/ha in both the years. One-third urea and other fertilizer were applied as basal during final land preparation. Remaining two-third urea were applied as top-dress in two equal splits at 15 and 35 days after emergence. Size of the unit plot was 3m x 3m and plant spacing was 30cm x 15cm. Intercultural operations were done as per needed. Harvesting was done in three times. Data on yield and yield attributes were collected and mean separation was done at 5% level of significance following LSD test.

Achievement/Findings:

Early sowing of Bush bean showed better performance in both the years. BARI Bushbean-1 and BARI Bushbean-2 may be cultivated from 9 November to 29 November for higher yield in the North-West region of Bangladesh.
