Effect of seeder displacement velocity and horizontal seed plate distributor on sorghum fodder (Sorghum bicolor L. Moench) emergence and productivity
Abstract
An experiment in randomized blocks with three replications was carried out to verify the effect of different seeder displacement velocity (3, 5 and 7 km/h) and kind of cell horizontal seed plate distributor (lateral and circular cells) on the emer- gence and productivity of sorghum fodder. Plant population was smaller for the largest speeds and for the horizontal seed plate distributor with circular cells. Plant distribution was affected by the sowing speed. The increase of speed reduced the plant height and the production of sorghum fodder dry matter at 60 days after sorghum sowing, not affecting the total production of dry matter (sorghum plus weeds). Grain yield decreased lineally with the increase in speed, being also smaller for the horizontal seed plate distributor with circular cells. Best performance in sorghum fodder sowing was obtained using lateral cell plate seed distributor and working at 3 km/h.
