Most producers in Virginia are trying to forget the difficult times in harvesting the 1999 crop and look forward to a much better year in 2000. On the other hand, continuous planting of one crop or closely related crops can reduce yields in just a few years. Perhaps the most fundamental of these truths is the importance of crop rotation. Crop rotation means to grow different crops in order or succession. Both approaches can be successful depending on the problems present.
Crop rotation is a long-established practice because it generally improves yield.
Among these reasons, the development of crop rotations for management of diseases and nematodes is probably one of the most important. How to Select Crops A crop rotation sequence can either increase or decrease the risk of yield losses to disease. Since peanut is a legume and highly susceptible to several diseases and pests, other legumes should not be grown in the year prior to planting peanut. Before selecting a rotation crop for peanut, it is important that you know the history of diseases in each field. The second step is to know the susceptibility of rotation crops to the diseases and nematodes in each field.
