Growth Response of Palm Trees to the Depth and Frequency Period of Irrigation by Bubblers in Khuzestan, Iran
D. Khodadadi-Dehkord, H.A. Kashkuli and A. Bavi

Abstract:
Based on the shortage of water resources in Iran country and the high evapotranspiration rate in Khuzestan region (2044 mm year-1), an irrigation system on Estamaran (Sayer) palm trees in the experimental farm of Shahid Rajaee of Omidiyeh plain was conducted. This study had two purposes, namely irrigation frequency period and suitable depth of irrigation application of the Estamaran palm trees in Omidiyeh region. Irrigation frequency was the primary treatment and the evapotranspiration estimating methods were the secondary treatments. Three irrigation levels i.e., one day long (A1), two day long (A2) and three day long (A3), were used as irrigation frequency period. Also the evapotranspiration estimating methods used were, Penman Monteith 100% (B1), Penman Monteith 70% (B2), Class A Pan 100% (B3) and Class A Pan 70% (B4). Since, this study had three replications, 36 palm trees were selected for this experiment. Irrigation scheduling was done according to SCS recommendations. Experimental design was according to split plot method in a randomized complete block design. Finally by measuring different growth indices of palm trees (number of leafs, number of thorn and leaflet length) at about two years (2006-2008), the results showed that the A1B2 treatment (Penman Monteith 70% and daily irrigation), at index of number of leaves, had a significant difference at 5% level. So, it recommended as the best treatment in this plan. In comparison with the uncontrolled bubbler irrigation by local farmers, using A1B2 treatment from Aug. to Nov. (2008) (the peak months for evapotranspiration data), would have 7344 m3 water saving per hectare per month.
