New technology continues to be developed to help farmers use their resources more efficiently. This research focuses on a method of planting crops in a twin-row configuration versus conventional planting. Farmers need to analyze many factors when considering switching from planting corn in thirty-inch rows and soybeans in seven and one-half or fifteen-inch rows, to planting in twin-rows.
The objectives of this research are: (1) Analyze the cost of alternative implements and how the differences in investment affect planting cost per acre. (2) Determine added cost per acre at planting higher corn populations in twin-rows compared to conventional thirty-inch rows. (3) Determine how much of a yield increase is needed to make higher corn populations with twin-row planting profitable. (4) Compare breakeven corn yield increase from objective three with results of recent field trials.
A higher initial investment results in a higher cost per acre for each implement due to the fact that the cost is based on the list price. There is an added seed and fertilizer cost of twenty-two dollars for planting at higher plant populations in twin-rows. An increase of 5.45 bushels per acre is needed for twin-rows to be profitable on a corn-soybean operation and a 6.68 bushel per acre increase for twin-rows to be profitable for a continuous corn operation. It was also concluded that in recent trials the required breakeven bushel per acre increase is obtainable to make twin-rows profitable for farmers.
