Impact of crop rotation and peanut rotation partners on leaf spot intensity, stem rot incidence, root knot nematode damage, and the yield of two peanut varieties was assessed in 2017. Peanut plots will be split to include the peanut root knot (Melotdogyne arenaria Race 2) resistant Tifguard and Georgia-14N along with the root knot susceptible Georgia-06G peanut cultivars to assess the interaction between peanut cropping frequency and value of a root knot resistant peanut cultivar. For 2017, only Georgia-14N and Georgia-06G peanut varieties were established. Peanut rotation sequences will include 27 years of continuous peanut production as well as peanut behind 1 year of com, bahiagrass, com, cotton, pearl millet, soybean, and summer fallow as well as peanut behind two years of pearl millet, cotton, and com. Cotton plots were split into four subplots of two cotton root knot resistant (Meloidogyne incognita race 4) cotton varieties
(Phytogen 487 and Deltapine 1558 RN) and two cotton root knot susceptible varieties (Phytogen 499 and Deltapine 1252  or Deltapine 1646 ) to assess the interaction between cotton cropping frequency and cotton variety selection as well as differential variety reaction to the disease target spot.
