Abstract/ Executive Summary:

The experiment was conducted at ARS, BARI, Banerpota, Satkhira and Kuakata, Potuakhali during the rabi season of 2008-09 to investigate the influence of sowing date on the performance of Soybean. Six dates of sowing viz. 10 December, 20 December, 30 December, 10 January, 20 January and 30 January were included in the trial under rainfed situation in a RCB design. It was observed that significantly the highest yield was obtained from 20 December sowing (1.45 t/ha) which was identical with 30 December sowing (1.40 t/ha) at Potuakhali. At Banerpota significantly the highest yield was obtained from 20 January and, 30 January sowing (1.99 t/ha) which was identical with 10 February (1.98 t/ha) and 10 January sowing (1.95 t/ha). Influence of date of sowing on the performance of soybean varied in both the locations.

Keywords: Sowing date, Yield and yield components, Soybean, Coastal areas

Location: ARS, Banerpota, Satkhira and Kuakata, Potuakhali

Start Date: 00-00-2008

End Date: 00-00-2009

Program Area: Crop-Soil-Water Management

Commodity: Soybean

Objectives:

To find out the optimum date of sowing for maximum growth and yield of soybean

Methodology:

The experiment was conducted at ARS, BARI, Banerpota, Satkhira and Kuakata, Potuakhali during the rabi season of 2008-09. Six dates of sowing viz. 10 December, 20 December, 30 December, 10 January, 20 January and 30 January were included in the trial The experiment was conducted in a randomized complete block design with 3 applications. The unit plot size 5 m x 2 m. Seeds were sown in line with a spacing of 30 cm x 5 cm. The variety Shohag was used in the trial. Fertilizers at the rate of 50-85-35 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 two times. Data for yield components were taken from five randomly selected plants from each plot. Collected data were analyzed statistically and the mean differences were adjusted by DMRT.
