Abstract

An on-farm survey was conducted in Nebraska to determine factors affecting corn seed spacing uniformity. Statistical analysis indicated that relative surface roughness, amount of residue present, amount of preplant tillage, and tillage system were important factors affecting uniformity. Subsequently, replicated tillage plots at eight locations were used to evaluate seed spacing uniformity with different planters and tillage systems. Seed spacing coefficient of variation and a planter index developed showed conservation tillage does not significantly reduce seed spacing uniformity.
