Predicting Double-Planting in Point Rows for Various Field Geometries
Track: Agriculture

Double-planting into end rows is costly in terms of additional seed and yield reductions in double-planted areas. Analysis of planter tracking data for 46 fields of varying shapes and sizes in Middle and West Tennessee found double-planting of point rows into the end rows varies from 0.1 to 20 percent of field area. The double-planted area is influenced by field geometry, planter width, operator skill and the presence or absence of planter section controls to start/stop seeding as planter sections enter/leave end rows. Economic analysis of planter automatic section control systems predicts positive cash returns and cost recovery as quickly as one season, depending on crops, acreages and field geometries. A tool based on Spatial Analyst was developed to predict double-planting areas based on field boundaries, planter size, terrain, and planting patterns. Producers can use this knowledge to make better decisions concerning fields to rent, equipment purchases and planting patterns.
