Abstract/ Executive Summary:

An experiment was conducted at Ishurdi, Pabna during kharif-1 season of 2002-2003 to find out the performance of seeder and weeder in different methods of sowing in mungbean cultivation. Three sowing techniques (Normal hand sowing, Sowing by BARI seeder and Bed planting) and three weeding techniques (One hand weeding at 25 DAE, weeding by BARI Weeder at 25 DAE + one hand weeding at 25 DAE and BARI weeder at 25 DAE) formed the experimental materials. Seeds of mungbean (cv. BARI mung-5) were sown on March 17, 2002 maintaining 30 cm x 10 cm spacing. No significant effect of different sowing techniques were observed on the yield of mungbean. However, the highest seed yield was obtained from Bed planting (1.06 t/ha) followed by BARI seeder (1.51 t/ha) and Normal hand sowing (1.45 t/ha). Different weeding techniques had a significant effect on seed yield. The highest yield (1.79 t/ha) was obtained when the plots were weeded by BARI weeder at 25 DAE plus one hand weeding at 25 DAE (1.65 t/ha). Economic analysis revealed that the highest gross margin (Tk 24492/ha) and benefit cost ratio (3.08) was obtained from BARI seeder sowing. On the contrary, the highest gross margin (Tk. 28758/ha) and benefit-cost ratio (3.02) was obtained from BARI weeder weeding at 25 DAE plus one hand weeding at 25 DAE.

Start Date: 17-03-2003

End Date: 25-05-2003

Program Area: Farm Mechanization

Commodity: Mungbean

Objectives:

To find out the performance of seeder and weeder in different methods of sowing in mungbean cultivation.

Methodology:

The experiment was conducted at Regional Agricultural Research Station, Ishurdi, Pabna, during khrif season 2003.Three sowing techniques (Normal hand sowing, Sowing by BARI seeder and Bed planting) and three weeding techniques (One hand weeding at 25 DAE, weeding by BARI Weeder at 25 DAE + one hand weeding at 25 DAE and weeding by BARI weeder at 25 DAE) were used in the experiment.The bed was prepared manually. The experiment was conducted in a split plot design with three replications. The sowing technique was assigned to the main plot and weeding techniques in the sup-plot. The unit plot size was 5m x 4.2 m. No fertilizer was used in the experiment. The mungbean variety BARI mung 5 was used as the test crop. The crop was sown on 17 March, 2003 maintaining 30 cm line to line distance and harvested on 25 May, 2003.

Achievement/Findings:

The highest yield (1.79 t/ha) was obtained when the plots were weeded by BARI weeder at 25 DAE +one hand weeding at 25 DAE (1.65 t/ha). Economic analysis revealed that the highest gross margin (Tk 24492/ha) and benefit cost ratio (3.08) was obtained from BARI seeder sowing. On the contrary, the highest gross margin (Tk. 28758/ha) and benefit-cost ratio (3.02) was obtained from BARI weeder weeding at 25 DAE + one hand weeding at 25 DAE.
