Nitrogen Partitioning in Young “Julyprince” Peach Trees Grown with Different Irrigation and Fertilization Practices in the Southeastern United States

Fertilizer recommendations for peach cultivation in the southeastern United States were developed decades ago and may not reflect trees’ needs under current practices. Adequate fertilization young trees induces a balanced vegetative/reproductive growth, ensures efficient resource use, is environmentally sound. Droughts region are becoming more common. Supplemental irrigation peaches from time of field establishment serves as insurance case drought conditions occur can increase/advance yield trees. Our objective was to determine influence different fertilizer levels (25, 50, 100, 200% recommended rate), (irrigated vs. non-irrigated), systems (drip micro-sprinkler) on nitrogen partitioning concentration organs The cumulative (N) removal per tree affected by levels. Most N allocation accounted summer pruning defoliation (68% total removed). Irrigated had higher after three years than non-irrigated trees, with differences between irrigated most vegetative events (winter pruning, defoliation). Drip-irrigated micro-sprinkler-irrigated tress, found reproductive events. Differences mainly driven dry weight rather organs. These results suggest that did alter indicating reduction applications be done without negative effects. Furthermore, induced greater especially conditions, which result canopy volume fruit compared consistent; however, drip micro-sprinkler irrigation, ~38% water savings.
