Abstract/ Executive Summary:

An experiment was conducted at Banerpota Farm, Satkhira to investigate the effect of sowing time on the performance of cowpea. Five different dates of sowing viz. January 4, January 19, February 18 and March 5 were included in the study. The dates of sowing had significant effect on the yield and yield attributes of cowpea. The highest seed yield was recorded from 4 January sowing due to high yield attributes.

Keywords: Cowpea, sowing time, coastal area

Location: Banerpota Farm, Satkhira, Kuakata PATUAKHALI

Start Date: 04-01-2006

End Date: 07-04-2007

Program Area: Crop-Soil-Water Management

Commodity: Cowpea

Objectives:

To identify the optimum sowing time of cowpea for the coastal region.

Methodology:

The trial was conducted at Satkhira MLT site, Satkhira during Rabi season, 2005-07 with five date of sowing (January 4, January 19, February 18 and March 5) of cowpea following RCB design with four replications. The unit plot size was 3m 2m. The experiment was initiated on 04 January, 2006 as line sowing. Line to line spacing was 30 cm. Fertilizer were applied at the rate of 20-16-17-10 kg/ha of N, P, K and S respectively. All Urea, TSP and MP were applied as basal. One irrigation was given at initial growth stage. All the intercultural operations were done as and when necessary. Data on yield and yield attributes were collected. The soil salinity level during 01 January’06, 15 January’06, 01 February’06, 15 February’06, 01 March’06, 16 March’06, 02 April ’06, 17 April’06, 02 May’06 and 16 May’06 were 3.23, 3.22, 2.89, 6.49, 5.53, 9.18, 8.68, 7.00, 8.10 and 3.42, respectively.

Achievement/Findings:

Higher plant population was observed in February 3 sowing followed by January 4 sowing. The tallest plant was observed from February 3 sowing. The plant height gradually increased with the delay in sowing. But pods/plant and seed/pod decreased gradually in delay sowing. Higher number of seeds/pod was obtained from January 4 sowing followed by January 19 sowing. Higher seed weight was obtained from 4 January sowing. The date of sowing influenced seed yield significantly. Seed yield obtained from January 4 sowing showed significantly the highest than other date of sowing. The highest yield was obtained from January 4 sowing could be due to maximum plant/pod and seed/pod. Seed was not formed in February 18 and March 5 could be due to high temperature.
