Peach Fairhaven trees were subjected to combinations of 2 rates of N fertilizer application (150 and 300 kg/ha as NH4NO3, reduced to 30 and 60 kg/ha, respectively, in the fourth year), single or split application of N, and year-round or partial annual control of vegetation within the tree row. Yield, leaf nutrient concentration and fruit quality were assessed over 6 growing seasons. Yield was increased by the higher rate of N in 3 of the 6 years. Vegetation control had little effect on yield.
