In the past few weeks we have seen peanuts expressing less than ideal color. I’ve provided Peanut Notes earlier in the year discussing some of the possibilities. There is very limited data on peanut response to products applied this late in the year relative to yield. What I have done in some cases is record yield in areas where there is some type of nutrient deficiency expressed in the canopy versus healthy plants. The issue is seldom caused by a single element, and in some cases it is related to issues affecting root growth that consequently affect nutrient uptake. In the few cases where I have recorded yield of yellow peanuts versus green peanuts, I do not see a difference in yield. This is the case when the yellow or discoloration occurs late in the season. Much earlier in the season efforts to correct an issue may be in order, but right now, within 3 weeks of harvest, that is little chance applied nutrients will have an impact.

It is also natural for the peanut canopy to change color as the plant ages and the focus of the plant is on reproduction – the pods. Pod demand can be quite high at this time of the year and nutrient deficiencies can be observed. Pods, like cotton bolls, are a major pull of some nutrients from the foliage. Applying nutrients to the foliage when this process is going on is very unlikely to change the color of leaves and increase yield.
