Abstract

The date of Majhoul quality gives much information on the conduct of the date palm cultivation. To assess the effect of the water regime on the quality and quantity of dates at the stage tamer, an experimental test was conducted for two consecutive years (March 2012-February 2014). Seven localized water regimes were applied: farmer regime (T0), 100 % (T1); 80 % (T2); 60 % (T3); 80-100-60 % (T4); 150 % (T5) and 60-100-80 % (T6) ETM. The measures focused on the measurement of the fresh weight and dry fruit, water content, total yield and the calibration dates according to general standards for the marketing of Moroccan date. The results showed that the water regime 60-100-80 % ETM has qualitatively and quantitatively improved the performance dates. While the regulated deficit water in the 40 % threshold has a significant effect on palm productivity by increasing class I at the expense of the Extra Class.
