Abstract/ Executive Summary:

The experiment was conducted at ARS, BARI, Benarpota, Satkhira and Kuakata, Potuakhali MLT site during the Rabi season of 2008-09 to investigate the influence of sowing date on the performance of mungbean variety as well as to avoid moisture stress caused due to late sowing after 15 January. Seeds were sown at four different dates viz. 20 December, 30 December, 10 January and 20 January under rainfed situation in a RCB design. At Banerpota significantly the highest yield was obtained from 20 January sowing (1.50 t/ha) followed by 10 January sowing (1.35 t/ha). 20 December sowing gave the lowest yield (1.20 t/ha) which was identical with 30 December sowing (1.30 t/ha). At Potuakhali significantly the highest yield was obtained from 20 December sowing (1.12 t/ha) which was identical with 30 December sowing (1.10 t/ha). The lowest yield was obtained from 10 January sowing (1.08 t/ha).

Keywords: Date of sowing , Yield and yield components, Mungbean, Coastal areas

Location: ARS, Benarpota, Satkhira and Kuakata, Potuakhali

Start Date: 00-00-2008

End Date: 00-00-2009

Program Area: Crop-Soil-Water Management

Commodity: Mungbean

Objectives:

The study was undertaken to find out the optimum date of sowing for maximum yield of mungbean.

Methodology:

The experiment was conducted at the ARS, BARI, Benarpota, Satkhira and Kuakata, Potuakhali MLT site during the late Rabi season of 2008-09. Four sowing dates such as 20 December, 30 December, 10 January and 20 January 2009 with BARI Mungbean -2 was used in the study. The experiment was conducted in a randomized complete block design with six replications. The unit plot size 5 m x 2 m. Seeds were sown in line with a spacing of 30 cm x 5 cm. Fertilizers and 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 of each plot. Collected data were analyzed statistically and the mean differences were adjusted by DMRT.
