An experiment was conducted from 2001 to 2009 in Louisiana to analyze the profit potential of a soyabean/wheat double-crop was compared to a monocrop system. Wheat was planted in early to mid-November each year, and soybeans were planted immediately following wheat harvest, generally in mid-May. Monocrop soybeans were generally planted in late April or early May. The difference in yield for the duration of the experiment averaged about 3.6 bushels per acre. Although the double-crop soyabeans had lower average yields, this system also had additional income from the wheat crop. Wheat yields ranged from about 40 to almost 80 bushels per acre and averaged 58 bushels per acre from 2002 through 2009. For most of the years, the double-crop system produced higher net returns than soyabeans alone. During the experiment, the double-crop system net returns were 58.89 dollars per acre higher than the monocrop soybeans. Based on this analysis, double cropping soybeans and wheat could add significantly to a producer's net income.
