Abstract/ Executive Summary:

A field experiment was conducted at the Regional Agricultural Research Station, Ishurdi, Pabna during kharif season, 2003, 2004 and 2005 to find out the performance of seeder and weeder in different methods of sowing in mungbean cultivation. Three sowing techniques viz., Normal hand sowing, BARI seeder sowing and Bed planting and three weeding techniques viz., one hand weeding at 25 DAE, BARI weeder weeding at 25 DAE + one hand weeding at 25 DAE and BARI weeder weeding at 25 DAE were compared in the study. In three year’s of experimentation, no significant effect of different sowing techniques was observed on the grain yield of mungbean, however, the higher grain yield was obtained from bed planting (1.60 t/ha in 2003, 1.53 t/ha in 2004 and 1.57 t/ha in 2005). Different weeding techniques had a significant effects on the grain yield of mungbean. The highest grain yield was obtained from BARI weeder weeding at 25 DAE + one hand weeding at 25 DAE (1.79 t/ha in 2003, 1.67 t/ha in 2004 and 1.62 t/ha in 2005) which was identical to one hand weeding at 25 DAE (1.65 t/ha in 2003, 1.59 t/ha in 2004 and 1.57 t/ha in 2005). Significantly the lowest grain yield was obtained from BARI weeder weeding at 25 DAE (1.10 t/ha in 2003, 1.04 t/ha in 2004 and 1.31 t/ha in 2005).

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 the Regional Agricultural Research Station, Ishurdi, Pabna, during kharif season 2003, 2004 and 2005. Three sowing techniques viz., Normal hand sowing, BARI seeder sowing and Bed planting, and three weeding techniques viz., one hand weeding at 25 DAE, BARI weeder weeding at 25 DAE + one hand weeding at 25 DAE and BARI weeder weeding at 25 DAE were included in the study. The bed was prepared manually in 2003 and bed planter was used in 2004 and 2005. The experiment was conducted in a split-plot design following three replications. The sowing technique was assigned to the main plot and weeding techniques in the sub-plot. The unit plot size was 5m x 4.2m. No fertilizer was used in the experiment. One irrigation was given at 30 DAE in 2004 and at 25 DAE in 2005. The mungbean variety BARI Mung-5 was used as the test crop. The crop was sown on 17 March in 2003, 23 March in 2004 and 22 March in 2005, maintaining 30 cm line to line distance and harvested on 25 May in 2003, 27 May in 2004 and 4 June in 2005. To control ‘Jassids’, Azodrin was applied at the rate of 2ml/litre of water at 30 and 45 days after emergence. Data on yield and yield contributing characters were taken and statistically analyzed and mean values were adjusted by DMRT.

Achievement/Findings:

The highest grain yield was obtained from BARI weeder weeding at 25 DAE + one hand weeding at 25 DAE (1.79 t/ha in 2003, 1.67 t/ha in 2004 and 1.62 t/ha in 2005) which was identical to one hand weeding at 25 DAE (1.65 t/ha in 2003, 1.59 t/ha in 2004 and 1.57 t/ha in 2005). Significantly the lowest grain yield was obtained from BARI weeder weeding at 25 DAE (1.10 t/ha in 2003, 1.04 t/ha in 2004 and 1.31 t/ha in 2005).
