Abstract
Abstract Ammonium sulfate at 1.0, 1.5 and 2.0 lb. of actual N, and ammonium nitrate at 1.5, 2.0 and 2.5 lb. N were applied in 1964 and 1965 to ‘Red Haven’ and ‘Giant Elberta’ peach trees in Western Colorado. Ammonium sulfate increased yields of ‘Red Haven’ peaches, but ammonium nitrate did not increase yields. All N treatments increased the concentration of N in the leaves. Some N treatments depressed the uptake of K and Fe, but increased Mn. Correlations between chemical leaf analysis and physical characteristics are presented. Nitrogen treatments delayed fruit maturity and increased shoot growth.
