Zinc, Phosphorus, and Lime Interactions With Yield and Zinc Uptake by Phaseolus Vulgaris1

Three levels of Zn (0, 7.5, and 15 pp2m) were added to each of 20 Michigan soils, which varied in pH and texture, and three successive crops of pea beans (Phaseolus vulgaris L.) var. ‘Sanilac,’ were grown in the greenhouse. Lime was applied to 5 of the 20 soils for the second crop and to 13 soils for the third crop. A heavy P application (500 pp2m P) was made on all soils prior to the second crop. The heavy P application generally induced a greater Zn deficiency on soils testing above pH 7.0 which contained free CaCO3. Pea bean growth was reduced by both Zn deficiency (below 20 ppm Zn in tissue) and toxicity (above 50 ppm Zn in tissue). Yields on the acid soils were generally decreased when Zn was applied; however, liming these same soils could induce Zn deficiency.
