| Resumo: | This study was done to evaluate the performance of a fertilizer spreader designed to incorporate organic compost in direct-seeding system of maize, by quantifying traction force requirement, hourly and operational fuel consumption, power demand, working capacity, compost incorporation in soil and the maize seedling emergence speed index. Traction force requirement, fuel consumption and working capacity were used to evaluate the performance besides compost incorporation depth and seedling emergence speed index. The fertilizer spreader can be used by low power (> 40 cv) tractors. The fertilizer spreader showed low working capacity and high operating fuel consumption. The designed was effective for incorporating compost into soil to a depth of up to 0.04 m. The incorporation of compost increased seedling emergence speed index by 36% in soil without millet chaff. |
