ABSTRACT In the southeast US, winter wheat as a double crop has proved to be very beneficial for soil management and profit to the farmers. Winter canola (Brassica napus L.) also has similar potential. Therefore, performance of winter canola in rotation and as a double crop with corn, sorghum, soybean and cotton were evaluated for two years. Rotational effects on canola plant height, number of pods per plant, number of seeds per pod and seed weight were not significantly different in comparison to fallow in 2003 but they were significant in 2004. The rotational effect on plant density was significant in 2003. In 2003, rotating canola after soybean significantly increased canola seed yield (2739 kg ha-1) than after fallow (2557 kg ha-1). In 2004, canola planted after soybean gave the highest yield (3129 kg ha-1), which was not significantly different than after corn (2937 kg ha-1) but was significantly higher than when planted after sorghum (2650 kg ha-1) or cotton (2521 kg ha-1). The fatty acid profile and saturated fat in canola oil were not affected by rotation. suresh.kumar@mailserver.aamu.edu
