Abstract/ Executive Summary:

The efficiency of BARI developed Seeder, Bed Planter and Weeder were tested in wheat field against existing seeding and weeding methods during 2002-2003 and 2003-2004 at the field of Central Research Station, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur. Three seeding methods- viz. seeding by hand (HS), seeding with BARI- Seeder (BS) and seeding with Bed planter (BP) and three weed control 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 used as treatment variables. Seeding methods significantly influenced grain yield of wheat in both the years. BARI seeder produced the highest mean grain yield (3.24 t/ha) and the lowest (3.10 t/ha) from hand seeding. Weeding methods significantly influenced grain yield in 2002-03 but not in 2003-04. Average over years, BARI weeder used at 25 DAE produced the highest grain yield (3.29 t/ha) and the lowest (3.14 t/ha) from one hand weed at 25 DAE. Maximum benefit cost ratio (1.61) was obtained when BARI-weeder was employed with bed planter followed by when BARI weeder was operated with BARI seeder.

Keywords: BARI-seeder, BARI-weeder, Wheat

Location: The field of Central Research Station, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh

Start Date: 00-00-2000

End Date: 00-00-2004

Program Area: Farm Mechanization

Commodity: Seeder, Weeder

Objectives:

To compare the efficiency of BARI developed Seeder, Bed Planter and Weeder to existing seeding and weeding methods.

Methodology:

The experiment was conducted at the field of Central Research Station, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during the rabi seasons of 2002- 2003 and 2003-2004. The soil belongs to Chhiata series under AEZ-28. The experiment was laid out in a split plot design with three replications. Seeding methods viz., hand seeding (HS), seeding with BARI seeder (BS), seeding with bed planter (BP) were placed in the main plots and three weeding treatments viz., one hand weeding at 25 DAE (T₁), BARI weeder + one hand weeding at 25 DAE (T₂), weeding by BARI weeder at 25 DAE (T₃) were assigned in the subplots. The unit plot size was 5 m X 4.8 m. The land was thoroughly prepared and leveled by ploughing and laddering. Weeds and stubbles were removed from the field at the time of final land preparation. Fertilizer @ 100-26-33-20- 4-1 kg N, P, K, S, Zn and B/ha were applied as urea, triple super-phosphate, muriate of potash, gypsum, zinc sulphate and boric acid, respectively. Two third of urea and all other fertilizers were applied at the time of final land preparation. Remaining urea was top-dressed at CRI stage (21 DAS) followed by first irrigation. Wheat seeds of Satabdi were sown continuously in line apart from 20 cm on 28 November 2002 and 22 November 2003 respectively. Four irrigation were applied at CRI, maximum tillering (45 DAS), anthesis (60 DAS) and grain filling stage (80 DAS). The crop was harvested on 15 March 2003 and 20 March 2004 respectively and yield data were recorded. Data on yield and yield contributing parameters were analyzed statistically and mean separation was done by DMRT.

Achievement/Findings:

Seeding by BARI Seeder and weeding by BARI weeder might be economically viable for a large-scale wheat cultivation considering easy operation or handling in Grey Terrace Soil of AEZ-28.
