Effect of the Date of Cuts of Irrigation In Postharvest Time On the Productivity and Quality of Superior Seedless for Table Grape In the Region of Caborca Sonora

In the state of Sonora, grapevine is one of the main crops, due to the economic special tax that originates and the manpower that generates. Between the main problems that presents the producing regions of the state (Hermosillo and Caborca), specially for the production of table grape, is the shortage of water availability and in spite of this the tendency is to irrigate and to fertilize more. The objective of the present study was: To determine the effect of the date of watering court in postharvest on the productive behavior and phonological stages of Superior Seedless cultivar. The evaluated treatments were: cut off the irrigation on: September 15, 30, October 15 and the control on October 30. The results indicate not statistical differences between treatment, but we observed a tendency to have earliest and bigger bubreak when irrigation cut off is early too, compared with the control (five days early), also we observed a tendency to present more clusters. However the next year, they were harvested more boxes in the first harvest time when the irrigation cut off was early.
