5973. Roth, G.W., R.H. Fox, and H.G. Marshall. 1989. Plant tissue tests for predicting nitrogen fertilizer requirements of winter wheat.. Agron. J. 81:502-507.
Three plant tissue tests for estimating supplemental N for winter wheat were evaluated: stem nitrate concentration, whole-plant N concentration, and crop uptake N. The whole plant test accounted for the most variation in relative yields, had the lowest spatial variability, and appeared to be best suited for the current wheat management system in PA. The stem nitrate test was most sensitive to short-term changes in soil N supply.
