Effects of Water Spray Timing After Pollination on Fruit Set, Yield, Physical and Chemical Properties of Two Date Palm Cultivars

Abstract

Field experiment was carried out at Ghour AlSafi in Jordan valley to study the effect of water spray time on Fruit set, yield and some characteristics on two date palm Cultivar ( Hayani and Zaghloly). Results of this investigation have showed that control treatment ( without water spray)  has better fruit set and yield in both cultivar, but has less fruit weight owing to the increase of yield. The least fruit set was noticed when water had been sprayed after 3 hours from pollination. The water timing spray did not significantly affected fruit length, diameter, flesh and seed weight, total and reducing sugars in Zaghloly date. On the other hand, Hayani dates was significantly affected by water timing spray particularly fruit diameter, length / diameter ratio and TSS.
