Abstract

This study was conducted during two successive seasons (2021, 2022) on seewy date palm cultivar growing in El Dakhla Oasis New valley governorate to investigate the influence of pollination following spathe cracking and hourse of day Time on fruit set and production of seewy date palm , three times after spathe cracking ( two, three and four days) were choice, and Three pollination Times during day (7am , 12pm and 5 pm ) were used, the obtained results showed that the earlier pollination after two days from spathe cracking increased fruit set percentage and Total yield with low quality of fruits, while delaying pollination to four days from spathe splitting gave lower fruit set percentage and lesser yield with high quality of fruits, on the other hand the highest fruit set percentage and Total yield were obtained with pollination performed at time (5pm) or before sun set followed by (12am) and (7am) in descending order, from the foregoing results it's noticed that under El Dakhla Oasis New valley governorate condition, the highest yield per bunch was obtained when pollination carried out two days after spathe cracking with time at (5pm) or before sun set, while the lowest yield per bunch was obtained when pollination performed the Fourth day after spathe cracking at time (7am).
