| The use of a multi-crop planter (MCP) attached to a compact 4-wheel tractor (4WT) is still not yet fully explored in the Philippines, despite the popularity of 4WT for land preparation in maize areas. A 4WT-attached MCP was developed for row seeding of rice, maize, and mungbean. This study evaluates the MCP adaptive model for maize in a field experiment and on-farm trials at two farmers’ fields during dry season. The MCP with seed metering plate having seven 12-mm diameter holes and 3-mm thickness had a seeding rate of 18.9 kg/ha which is within the targeted design range (15–20 kg/ha), a field capacity of 0.14 ha/h and field efficiency at 78% in well-tilled-clay soil under controlled condition. In farmer’s fields, the MCP delivered seeding rates within... |
