Abstract/ Executive Summary:

A field experiment was conducted at the MLT site Kuakata, Patuakhali during rabi, 2008 to find out the optimum sowing time of mungbean. Three sowing times viz. 01 January, 10 January, and 21 January 2008 and three variety (BARI mung-2, BARI mung-5 and BM 01) were included in the experiment. The yield was higher in 2nd and 3rd sowing than 1st sowing. On the other hand BM 01 gave comparatively higher seed yield due to salt tolerance ability more than others. The highest yield (0.956 t/ha) was obtained when BM-10 sown on 10 January.

Keywords: Date of sowing, mungbean , growth, yield, , saline area

Location: MLT site Kuakata, Patuakhali, and Kadamshahar, Rajshahi

Start Date: 15-03-2006

End Date: 29-03-2008

Program Area: Crop-Soil-Water Management

Commodity: Mungbean

Objectives:

The experiment was conducted to find out the optimum date of sowing for maximum growth and yield of mungbean

Methodology:

The experiment was laid out in RCB design having three replications with three varieties/lines sown in three sowing time. Seeds were sown in a continuous row keeping line to line 30 cm apart. Mungbean varieties BARI mung-2, BARI mung-5, and BM 01 were used. Seeds were sown in three different sowing dates as 01 January, 10 January and 21 January, 2008. The land was fertilized with 50-85-35 kg/ha Urea, TSP and MP as basal dose. Harvesting was done on 22 March, 25 Marchand 29 March, 2008, respectively. Yield and yield attributes were recorded and analyzed statistically. Salinity of the experimental plots was ranged from 1.70-4.20 dS/m during the period of mungbean of production.

Achievement/Findings:

Sowing time significantly differed plant height and seed yield of mungbean. The tallest plant height was recorded in 10 January sowing which was statistically identical to 21 January. Both 2nd and 3rd sowing date gave higher and identical seed yield/ha. The lowest yield was recorded in 01 January sowing. Plant height, number of seeds /pod and seed yield ha-1 differed significantly. The highest plant height was found in BM 01 and the lowest in BARI mung-5. But number of seeds/pod was the highest in BARI mung-5. The highest seed yield ha-1 was found in BM 01 which was significantly different from other two varieties. It might be due to more salt tolerance ability of BM 01 than other varieties. Combined effect of sowing time and variety was significant in case of plant height, number of seeds /pod and seed yield ha-1. The highest and statistically identical plant height was observed in D1 × V1 and D2 × V1 and it was lowest in D3 × V3 treatment. Number of seeds /pod was highest where BARI mung-5 was used which might be due to characteristics of the variety. The highest and identical seed yield was observed in D2 × V1, D2 × V2 and D3 × V1 treatments. It might be due to more salt tolerance ability of BM-01 and prolonged cold weather in 01 January sowing. The lowest seed yield was observed in D1 × V2, D1 × V3 and D3 × V3 treatments. Lower temperature during growing season increases the life span of mungbean and in the coastal belt mungbean should be sown at the time of Joe condition just after harvest of T.aman rice.
