Abstract
Nitrogen and P fertilization increased growth of 1 and 2 year-old highbush blueberry plants (Vaccinium corymbosum L., cv Wolcott) at 2 locations in eastern North Carolina. The influence of K upon growth during the years of establishment was not conclusive. Dolomitic lime application prior to establishment raised soil pH from 3.7 and 3.9 to 4.5 and depressed growth.
The influence of treatments upon the foliar contents of N, P, K, Ca, Mg, Fe, Cu, Mn, and Zn was determined. A direct relationship existed between the rate of N, P, or K and the content of these elements in the foliage. The only effects noted from lime application were an increase in P and Ca and decrease in Fe foliar level at one location. Variations in foliar elemental content, induced by treatments, were usually similar at both locations. The level of certain elements in the foliage, however, varied widely with location.
