Abstract/ Executive Summary:

A field experiment was conducted at MLT site Kuakata, Patuakhali during rabi, 2006-07 to find out the effect of date of sowing on growth, yield and yield components of cowpea. Seeds were sown on Dec. 11, 2006, Dec. 21, 2006 and Dec. 31, 2006 with three dispersed replication. The highest yield was obtained from 11 December sowing (1360 kg/ha) followed by 21 December sowing. 31 December sowing failed to germinate moisture stress durinf germination. From the study it was found that maximum yield was recorded from 11 December sowing which might be attributed to maximum population per unit area, maximum pods per plant and maximum seed per pod. It may be concluded up to Middle of December would be the optimum time of sowing for cowpea after harvest of T.Aman in the coastal area.

Keywords: Performance, Cowpea, Sowing time, Costal area

Location: Kuakata, Patuakhali

Start Date: 00-00-2006

End Date: 00-00-2007

Program Area: Crop-Soil-Water Management

Commodity: Cowpea

Objectives:

To identify the optimum sowing time of cowpea in coastal region to avoid salt stress and for getting maximum yield .

Methodology:

The experiment was conducted at the MLT site Kuakata, Patuakhali during the Late rabi season of 2006-07. Three sowing dates such as 11 December, 21 December and 31 December 2006 with cowpea variety BARI falon 2 was used in the study. The experiment was conducted in a RCB design with three dispersed replications under rainfed condition. The unit plot size was 5 m x 2 m. Seeds were sown in line with a spacing of 30cm x 5cm. Fertilizers @ 30-45-30 kg/ha Urea, TSP and MP were applied as basal during final land preparation. All other intercultural operations were done as and when necessary. Harvesting of pods was done in two times. Data for yield components were taken from five randomly selected plants of each plot.

Achievement/Findings:

From the study it was found that maximum yield was recorded from 11 December sowing which might be attributed to maximum population per unit area, maximum pods per plant and maximum seed per pod. It may be concluded that up to Middle of December would be the optimum time of sowing for cowpea after harvest of T.Aman in the coastal area.
