A study was conducted over 3 years to determine the yield of sorghum Sorghum bicolor (L.) Moench and soybean Glycine max (L.) Merr. grown as monocrops and in rotation on different soil types treated withinsecticides or nematicides at planting in consecutive growing seasons in Mississippi, U.S.A. Cyst, stunt, lesion, and spiral nematodes were consistently detected on different soil types during all growing seasons. When the reproductive capability of these 4 nematodes was assessed, location was a significant main effect reflecting responses to the different soil types. At a specific location, there were differences in nematode reproduction rates between rotations. Crop rotation significantly increased yield of both sorghum and soybean. An alternate year rotation resulted in yield advantages over monocropping.Accessibility Summary:
