Abstract
To test the effect of regulated deficit irrigation on the productivity of date palm cv Majhoul, an experiment was conducted for two consecutive years (March 2012-February 2014). During these times, seven water regimes were applied under drip irrigation: 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 monitoring of meteorological parameters, the water irrigation and the evolution of date yields of Majhoul variety. The results obtained show that: i. Water regime has significantly affected the average yields and water use efficiency, ii. Water irrigation needs are, on average, 51 m3/tree/year, and iii. Average date yields and water use efficiencies varied between 31 and 61 kg of dates/tree/year and between 0.44 and 1.36 kg of dates/m3.
Keywords: Regulated deficit irrigation, date palm, Majhoul, water use efficiency.
