Abstract
Tracking the nutrient element content of peanut leaves over the entire fruiting season revealed significant changes in certain essential elements during short periods. These short‐term changes may be more influential on yield than the general changes of nutrients shown over the entire growing season. Following heavy rains in May 1976, there was a drop in the N, B, Mn and Zn content of leaves. In both 1976 and 1977, there was an observed significant and continued drop in the N, K and B content of leaves when nut fil was most rapidly occurring. There was evidence that when the elements N and K are higher in leaf tissue prior to nut fill, this may contribute to higher nut yield.
