Abstract/ Executive Summary:

Performance of BARI developed Seeder, Bed-Planter and Weeder was tested against existing seeding and weeding methods in mungbean field during Kharif-1 2004 at Joydebpur and RARS, Ishurdi. Three seeding methods viz, seeding by hand, seeding with BARI-Seeder and seeding with BARI Bed Planter and three weeding methods viz., one hand weeding at 25 days after emergence (DAE), BARI Weeder + one hand weeding at 25 DAE and BARI Weeder at 25 DAE were arranged in a split-plot design. Seeding methods had no significant influence on mungbean yield at both the locations while that was significant for weeding methods. The highest grain yield and BCR were obtained from BARI Weeder along with hand weeding followed hand weeding. The lowest was obtained from BARI Weeder.

Location: Joydebpur

Start Date: 29-02-2004

End Date: 27-05-2004

Program Area: Farm Mechanization

Commodity: Weeder, Weeder

Objectives:

The experiment was undertaken to compare the performance of BARI Seeder, Bed Planter and Weeder with existing seeding and weeding methods.

Methodology:

The experiment was conducted at the Central Research Station Joydebpur, Gazipur and RARS, Ishurdi, Panba during kharif-1 season, 2004. Three seeding methods viz. seeding by hand, seeding with BARI Seeder and seeding with Bed Planter, and three weeding methods (one hand weeding at 25 DAE, BARI Weeder + one hand weeding at 25 DAE and BARI Weeder at 25 DAE) were arranged in a split-plot design following three replications. The sowing method was assigned to the main plot and weeding method in the sub-plot. The unit plot size was 5 m x 4.8 m. Fertilizers were applied @ 20-20-20 N, P and K kg/ha as basal. The mungbean variety BARI mung 5 was used as the test crop. The crop was sown on February 29 at Joydebpur and March 25, 2004 at Ishurdi maintaining 30 cm line to line distance and harvested on 12 and 27 May 2004, at Joydebpur and Ishurdi, respectively. Data on yield and yield contributing characters were taken and analyzed statistically and mean separation was done by DMRT.

Budget: 10,000/-

Total Budget (Tk.) : 10,000/-

Achievement/Findings:

Different types of weeds were present in the experimental field at Joydebpur among them the dominant species were Cynodon dactylon and Digitaria sanguinalis. Comparatively higher fresh and dry weight of weeds was found in BARI-Seeder and BARI-Weeder used plots. The highest grain yield and BCR were obtained from BARI Weeder along with hand weeding followed hand weeding. The lowest was obtained from BARI Weeder.
