“…Khalas) fruit development were studied under various irrigation treatments. The range of the quantity of chemical components was similar to that previously obtained for date palm fruit grown under northern Oman conditions (El Mardi et al, 1995, 1998, 2002Al-Kharusi et al, 2007) and change in chemical composition during fruit growth followed those previously reported.…”

Date palm (Phoenix dactylifera L.) is primarily cultivated in the regions of the Middle East and North Africa that are characterized by high evapotranspiration, low and sporadic rainfall and dependency on irrigation for crop cultivation. The effects of sub-optimal irrigation on the chemical properties of dates were investigated. Chemical quality attributes of date palm (cv. Khalas) grown in northern Oman showed variable responses to reduced frequency of irrigation water applied during fruit development. Trees irrigated on a daily basis showed a significantly higher fruit water content, juice volume, and titratable acidity (TA). Deficit irrigation treatments had the highest total-and reducing sugar content. Trees under water stress that were irrigated once per week showed significantly high dry matter, total soluble solids (TSS) and pectin. Sucrose, tannin and pH were not significantly different among irrigation treatments. Manipulation of irrigation frequency can be used to enhance certain chemical fruit quality attributes of dates.

“…Due to the general concern with respect to the use of chemicals in agricultural production, more save and economic thinners or methods are critically required. In mechanical pollination, dilution of pollen concentration with wheat flour might be a way to regulate fruit set (El-Kassas and Mahmoud, 1986a;and El-Mardi et al, 1995). Intended delay of pollination is another way of regulating fruit set, since the receptivity of pistillate flowers decreases by delaying pollination to one or two weeks from female spathe cracking.…”

Pollination and thinning are critical processes in the date palm production chain that affect fruit development, quality and yield and regulate tree yearly bearing. Developing a pollination technique that results in an acceptable level of fruit set with a minimum amount of pollen grains and without a further need for thinning is critically required for date palm production, especially under arid conditions. During 2006 and 2007 seasons, the effect of pollen grains-water suspension application at different concentrations on fruit set, yield and quality were examined on 'Lulu' date palm cultivar growing under Al-Ain oasis conditions, UAE. The results showed that pollen grains-water suspension (PGWS) application at 0.5, 1, 1.5 g/l gave fruit set percentage of 75.6, 86.8, and 87.8%, respectively which was lower than control (90.0%),traditionally pollinated). As the mean of both seasons, the PGWS application especially at 0.5 and 1.0g/l significantly decreased both bunch weight (5.52, 6.21, 7.19 and 8.54 kg for 0.5, 1.0, 1.5g/l and control, respectively) and total yield per tree (49.71, 55.92, 64.74 and 76.89 Kg/tree, for 0.5, 1.0, 1.5g/l and control, respectively) at the Tamer stage. Fruit quality characteristics especially fruit and flesh weight, length and diameter, TSS and dry matter concentration were slightly but significantly increased by the PGWS application treatments during the 2006 season. However, seed weight, acidity and vitamin C concentration were not affected by any of the pollination treatments. More research work is required for such pollination technique to justify the concentration of grains-water suspension and the response of each date palm cultivars to this pollination technique.
