THE EFFECT OF DIFFERENT TIME OF IRRIGATION ON OCCURRENCE OF EARLY SPLIT (ES) OF PISTACHIO NUTS

N. Sedaghati, H. Alipour
Early split (ES) fruits are known as undesirable products, which both the fruit’s hull and shell split before maturing. Insects and molds, especially those that produce the potent toxins aflatoxins, usually invade these fruits. The present study was carried out in the Rafsanjan suburb pistachio orchards during 2001-2004. The study comprised 10 treatments including two irrigation intervals (25 days, 45 days) and five irrigation skipping in each irrigation interval. During the growing season, amount of ES pistachio fruits was evaluated in experimental plots. Our results indicated that long irrigation intervals and deficit irrigation of pistachio trees in late April until early June increased substantially (until 90%) ES formation in comparison to regular irrigation, at harvest stage. Overall importance of suitable irrigation management had been illustrated in decreasing of ES nuts formation.
