no,self (fertilization) pollination is impossible in date palm
,Date palms develop as either a male or female of the species. The males produce pollen from massive flowers, which are then used to pollinate the fruit buds on the female trees that will then produce the fruit. Unfortunately, pollination doesn’t happen reliably enough on its own, so we need to help it along by hand. The reason for this? Oddly enough, birds and bees aren’t particularly attracted to date flowers, so we can’t count on them to carry the pollen from the male to the female tree. Left to its own devices, the wind would do part of the job, but it is also not very reliable. If we had to count on wind pollination, that would mean that a full half of our trees would have to be male, reducing the crop by a considerable amount. To maximize our yields and ensure good fruit set, we take matters into our own hands. Labor-intensive, yes. But the benefit to manual pollination is that one male tree can pollinate 40 or even 50 females, allowing us to thin out the male tree population and focus on nurturing the females.
