Cropping systems research encompasses a large topical area for research. Projects related to agronomic practices, preceding crops (whether commercial or cover crops), rotations, and many other topics fit into this area, so research under this umbrella is quite diverse and changes over time as new questions arise. 
Rotation trials continue to be evaluated, although are not staggered or replicated in such a way that all possible rotation sequences are available for comparison in every year. In 2015, there were few comparisons that could be made for the rotations that were scheduled for peanut in this cropping season. The continuous peanut rotation continued to have poorest results for both yield and grade in the soybean-peanut rotation trial, although half of the plots planted to peanut this year were simply to reset the rotation sequences so they would fall to peanut in the appropriate year when the cycle comes to full completion again in 2017 and 2018. When peanut followed various winter vegetable crops, there were no differences in yield or grade regardless of the winter species planted, however each of those plantings were followed by a spring vegetable or fallow immediately prior to peanut and yields and grades were better when preceded by fallow than when squash or cucumber were grown ahead of peanut, similar to the 2013 data.
