The irrigation effect on nuts’ growth and yield of Carya illinoinensis

Abstract Pecan trees require adequate soil moisture conditions to produce nuts with good yield and quality. Irrigation should be an important considered practice in orchards management plan, mainly regions water deficit periods. The objective of this research was evaluate irrigation on pecan growth yield. This study conducted Uruguay, during the fast development phase until harvest. Three treatments were used: 0 L (control), 70 140 plant-1 every two days, applied via drip seven-year-old cultivar Success. number per cluster nuts’ diameter length evaluated nut growth. After harvesting, peeled width measured, after peeling, kernel length, width, height filling peel percentage evaluated. According results, it possible identify that periods affected stageand size. plants provides greater dimensions mass. With use plant-1, there increase mass more than 100% relation from without irrigation.
