International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &<br />

Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad<br />

design a suitable intercrop planter that is able to perform the above said functions without<br />

damaging the seed and also reduce the cost <strong>of</strong> seeding as well as energy.<br />

Objectives:<br />

1. To design and development <strong>of</strong> intercrop planter for selected crop<br />

2. To evaluate the performance <strong>of</strong> developed intercrop planter<br />

3. To compute the economics <strong>of</strong> intercrop planter.<br />

Methodology<br />

Some agronomical practices <strong>of</strong> selected crops<br />

Crop Variety Seed rate (kg/ha)<br />

Row to row<br />

spacing (mm)<br />

Plant to plant<br />

spacing (mm)<br />

Castor GCH-7 5 1200 600<br />

Green gram GM-4 12-16 450 100<br />

The design considerations followed for mechanical components <strong>of</strong> prototype intercrop planter<br />

are explained under the following headings:<br />

1. Design <strong>of</strong> furrow opener<br />

2. Design <strong>of</strong> frame<br />

3. Design <strong>of</strong> power transmission system<br />

4. Design <strong>of</strong> seed metering mechanism<br />
