Laboratory And Field Testing Of Seed Spacing Uniformity For Sugarbeet Planters, Jonathan W. Panning, Michael F. Kocher, John A. Smith, Stephen D. Kachman

Biological Systems Engineering: Papers and Publications

Five planter configurations were evaluated for seed spacing uniformity at three field speeds using a seed location method in the field and a laboratory method involving an opto-electronic sensor system. Planter seed spacing uniformity was described using the Coefficient of Precision (CP3) measure. Results showed that CP3 measures determined using the laboratory test method were significantly different from those determined using the field test method. This indicated the laboratory test method cannot be used to predict planter seed spacing uniformity in the field. Seed spacing uniformity determined in laboratory tests was higher than, or equal to, seed spacing uniformity determined …
