Effect of Fertilizers on Yield, Quality and Nutrient Uptake by LettuceStrohlein, J. L.; Tucker, T. C. (College of Agriculture, University of Arizona (Tucson, AZ), 1965-08)A series of studies on lettuce fertilization have been carried out over the past few years. Fertilizer applications increased yield through increased head size and did not affect the number or quality of harvested heads. The lower rates used were as effective as the higher rates. Nitrogen and phosphorus fertilization generally increased the nitrate and phosphorus content of the various plant parts selected for analysis.
