Abstract

This study was carried out on six-year-old date palms (c.v Piarom) in Hormozgan Province, Iran, during 1994-2001. In this study, two volumes of water and two irrigation systems were compared in a randomized complete block design (RCBD) in a factorial arrangement in three replications. Each replication consisted of four date palm trees with following four treatments: A1= drip and A2= SURFACE IRRIGATION method, B1= water use based on 75%, and B2= 100% evaporation from class A pan. Water use was calculated based on ETP class A pan method by following formulas: ETo= Ep ×Kp, ETc= ETo × Kc, I=ETc × S / ŋ, in which ETo = Reference evapotranspiration, Ep = Pan evaporation, Kp = Pan coefficient, Kc = crop coefficient, I = Irrigation requirement, S = surface, ETc = Crop evapotranspiration, and Ŋ= efficiency of irrigation system. Irrigation interval in DRIP IRRIGATION was two days and for SURFACE IRRIGATION it was weekly. The results showed that there were no significant effects of treatments on the yield, and quality of fruit, such as pH, TSS, total sugar, reduced sugar, sucrose, moisture percentage, and dry matter percentage. The results of the study showed that water requirement in treatments of DRIP IRRIGATION based on 75% evaporation of class A pan (Ep), DRIP IRRIGATION based on 100% Ep, surface irrigation based on 75% Ep, and SURFACE IRRIGATION based on 100% Ep were equal to 23.7, 42.65, 57.46, 100.45 m3/tree/year, respectively. Also the results showed no significant effects of treatments on the YIELD and quality of fruit, except for titratable acidity that was significant (P<0.01). Therefore, due to many advantages such as more efficient use of water, low cost, easy to schedule and manage, and easy to automate, DRIP IRRIGATION is recommended as the best irrigation method for date palm plantation in southern Iran.
