Abstract
Abstract Date palms require pollen transfer from male to female palms in order to yield a fruitful harvest. The traditional method of accomplishing this artificial cross-pollination involved climbing each palm tree and physically putting male flower spikelets on female inflorescences. This process required a great deal of labor and was time-consuming. Due to developments in farming practices during the modern age, farmers have experimented with mechanical pollination systems. Recently, to pollinate date palms very quickly, safely, affordably, and with a minimum of risk of injury, agricultural drones have been used. In this research, experiments on drone dispersal pollination are conducted on three Omani date palm cultivars—Al Naghal, Al Khanezi, and Al Kasab. The applicability of this method is evaluated by comparing its fruit yield properties to those of the conventional method, which is commonly employed, and the less popular machine/hand pollination methods. The main limitations of drone dispersal pollination are, its inability to disperse exact amount of pollen to the target location of female inflorescences, especially in shorter palms; wastage of pollens and environmental pollution. The study recommends the use of a novel design of extendable pollen sprinkler for target-specific pollination in order to increase pollination efficiency and decrease DPP waste. The designed system comprises of a robotic arm extension with a remotely controlled sprayer mounted on a computer vision android device; that can shoot themselves out to the female flowers and disperse the required amount of pollens in the specific location. This unique spraying mechanism can overcome the drawbacks of aerial pollination and increase its effectiveness.
