Collapse ▲As we move towards planting the 2025 peanut crop, there are many pressures on financial stability. Higher prices of inputs and depressed commodity prices have caused some farmers in the V-C region to consider modest increases in peanut acreage. When looking at the contribution of income to a farming operation, some of our most dependable crops in a rotation with peanuts are struggling. This decision is made on a farm-by-farm basis and there is not a singular answer. What are the impacts of a less-than-ideal previous crop sequence for peanuts in 2025? Equally important, how will peanuts planted in 2025 affect peanuts down the road? Crop rotation studies at universities and with USDA can give us insight into the possible impacts. Grower observations do as well, and the folks that make recommendations to them. Many crop sequences have not been evaluated from a research perspective. Some of the findings we have in North Carolina can give a grower an idea of what more soybeans in the rotation can do to peanut yields. In those trials, we often look at the interaction of crop rotation and other practices such as fumigation and/or variety resistance. In many cases, the resistant variety or fumigation helps overcome a poor rotation for peanuts. However, this is not always the case. There is no substitute for a good rotation but there are ways to get a lot of the yield back following a poor rotation. The answer is site specific.
Speaking of “no substitutes.” I have gotten a few questions about inoculation for nitrogen fixation. In new peanut ground, there is no substitute for successful inoculation. Do whatever you have to do to get a liquid inoculant in the bottom of the seed furrow. Apply a peat-based inoculant with the seed for insurance as well. I would do both in new ground, but the in-furrow application is off the charts in terms of importance. It will be the most important input in a new ground setting. The peat-based product placed directly on seed will help partially overcome issues with equipment. In new ground, our work shows that yields of non-inoculated peanuts are 65% of inoculated peanuts. In rotated ground, we often see yields that are 5% greater when peanuts are inoculated. Inoculation pays for itself in all cases.
