A relatively new production technology which is being adopted by Northeast Louisiana (NELA) producers is 30-inch row spacing cotton production. Thirty-inch row cotton production has increased substantially in Louisiana between 1991 to 1992 (6,674 to 4,350 acres). (1) With the development of narrow row spacing harvesting equipment, 30-inch row cotton production is a technically feasible option. This paper addresses the issue of the economics of 30-inch row cotton production using whole-farm analysis. Information on production requirements and yield response was obtained by surveying 30-inch row cotton producers in NELA and area researchers. Enterprise budgets were developed for 30-inch row cotton, soybeans and corn production using 10 row equipment and for conventional 40-inch row production using 8-row equipment. Data from the budgets were used as inputs into a whole-farm linear programming model. The model was structured to capture the long-run investment aspect associated with adopting 30-inch row technology. The model was designed to select the profit maximizing row-spacing technology for a typical NELA farm with resources to produce cotton, soybeans and corn. Results of the model indicated that even with no yield differences between 30-and-40-inch cotton, the 30-inch technology yielded higher net returns. Assuming a 1 percent yield advantage with 30-inch cotton, whole-farm returns were $37,846 higher using the 30-inch row technology.
