Foliar Nitrogen and Potassium Variation in Cottonwood as Affected by Genetic and Site Factors

Genetic and soil factors accounted for 49 percent of the variation in foliar N and 60 percent of the variation in foliar K among four good and four poor cottonwood clones grown on productive and unproductive soils in Mississippi. Variation in foliar N was associated primarily with the clone X soil interaction; variation in foliar K was related chiefly to clonal differences. Additional keywords : Populus deltoides , soil N, soil K, clonal selection, N fertilization.
