Abstract/ Executive Summary:

A power tiller operated inclined plate multi-crop planter has been design and developed in the research workshop of Bangladesh Agricultural Research Institute (BARI), Gazipur. The main components of the planter are frame, seed hopper, inclined plate seed metering device, seed delivery tubes, furrow opener, soil compaction roller, dock clutch, and chain sprocket. Different functional 'parts were assembled on a main frame and it was attached to the rear of the power tiller with rotary replacing the tail wheel. The planter was tested for planting maize and wheat. Before planting, the seed-metering plate for particular crop was fitted to the seed hopper. The metering plate was uniformly rotated and there was no missing cell as the constant power form the driving wheel axle through dock clutch is obtained. The row to row and plant to plant spacing for maize were 75 cm and 25 em, respectively. The row spacing for wheat was 20. The planting capacity was 0.2-0.25 ha/hr at the speed of operation was 2-3 km/hr. The weight of the planter unit was 25 kg and price is Tk. 8000. The planting cost for maize and wheat are Tk. 300 and Tk. 400 per ha, respectively. At the current wage levels, the planter have break-even points for maize and wheat are l.70 ha/yr and 2.50 ha/yr respectively compared to that of the manual methods.

Program Area: Farm Mechanization

Commodity: Planter

Objectives:

To design and fabricate a power tiller operated planter for planting and sowing of maize and wheat
To test planter for planting and sowing maize and wheat, modify the planter if needed.
To compare the cost of planting with traditional methods.

Methodology:

The main components of the planter are (i) frame, (ii) seed hopper, (iii) inclined plate seed metering device, (iv) seed delivery tubes, (v) furrow opener, (vi) soil compaction roller, (vii) dock clutch, and (viii) chain sprocket. The planter was tested at Bangladesh Agricultural Research Institute, Joydebpur, Gazipur. It was operated by a 12 hp power tiller at a speed of l.5-4.0 km/hr. Before planting, the seed-metering plate for particular crop was fitted to the seed hopper. The metering plate is uniformly rotated and there is no missing cell as the constant power form the driving wheel axle through dock clutch is obtained. Maize seeds were planted at 3-4 cm depth with a row spacing of 75 cm and plant to plant spacing of 25 em. The planter covered 2 rows (75 cm width) in single pass. Maize seed rate was 22 kg/ha. Wheat seeds were sown at 3 cm depth and row spacing of 20 cm. The planter covered 4 lines (80 cm width) in single pass and the seed rate of wheat was 100 kg/ha. After germination of seeds, plant population was counted.

Achievement/Findings:

Power tiller operated multi-crop planter has been designed, developed and tested for planting and drill of maize and wheat, respectively changing by the metering plate. Seed rate and operational cost are lower than the traditional method. The planting cost for maize and wheat are Tk. 300 per ha and Tk. 400 per ha respectively. Power requirement of this planter is within the capacity of the power tiller. Planter field capacity depend on the skill of the operator and soil condition, for maize and wheat 0.25 ha/hr and 0.20 ha/hr, respectively. At he current wage levels, the planter have break-even points for maize and wheat are 1.7 ha/yr and 2.5 ha/yr respectively compared to that of the manual methods.
