Abstract/ Executive Summary:

Bokto seeding technology was developed and manufactured by the South Korea. During 2009, BRRI received a Bokto seeder from M/S Kumkangkikun Co Ltd. South Korea as donation. This is a 9-row multipurpose seeder suitable for cereal seeding. A 52 hp 4 WD tractor with PTO facility is needed to operate the machine. A team of two Korean engineers helped in field testing of the Bokto seeder during May 2009 in Bangladesh. The first field trial was conducted with BRRI dhan43 in Aus season in BARI farm, Gazipur and seed rate was found 50 kg/ha. Seeding and fertilizer dispensing rate were also found uniform and placed at a proper depth. Crop yield was 3.29 t/ha.

Start Date: 01-07-2008

End Date: 30-06-2009

Program Area: Farm Mechanization

Commodity: Seeder

Objectives:

To evaluate the performance of Bokto seeder

Methodology:

In May 2009, a team of two engineers from the Kumkangkikun Co. Ltd. visited BRRI for a week for field testing of the Bokto seeder in Bangladesh. FMPHT division in collaboration with the Agronomy division was working as a team for testing and evaluation of seeder for rice seeding. Field testing of Bokto seeder was arranged in BARI HQ farm under TCRC division. Dry seed of BRRI dhan 43 for Aus variety was used in the test. It consists of 9 row seed, fertilizer and silicate metering device, seed, fertilizer, and silicate box and seeder monitor. Seeder monitor send signal for any blockage in the seed delivery tube. A metallic round shaft was used for soil covering of the row. With this machine, cereal seeding in row, deep and side banded placement of fertilizer (TSP and MP), seed covering (sand) and soil covering were done. BRRI recommended fertilizer doses for rice were used. The machine consist of 9 rows with total seeding width of 234 cm and row to row distance is 26 cm. Sowing depth of fertilizer and seed was 3.7 cm. It has 9 seed and fertilizer boxes. Each seed box can hold up to 4.3 kg of rice seeds. Capacity of each fertilizer box was 10 kg. Total capacity of silicate box was 236 kg. The use of silicate is optional; instead of silicate coarse sand can be used as seed covering. To operate this seeder, a 52 hp four wheel drive tractor which receiving power from the tractor’s PTO was needed. Land was prepared by tractor and rotavator. The plot size was 164 m2, the soil type was sandy loam. The sowing and harvesting date was 19/05/2009 and 30/08/2009 respectively. Row to row spacing was found 26 cm.

Achievement/Findings:

The field operation of this machine was found satisfactory. Seeding of paddy in row, placement of fertilizer and sand coverage on seed in the field was uniform and at proper depth. Second research trial had been planned for Boro season 2010 at BRRI HQ farm. More field trials to be conducted next year in other agro-ecological zone of Bangladesh.
