This experiment was conducted at the experimental farm of Siwa Oasis Research
Station, Desert Research Center (Khimisa Farm), Marsa Matrouh, Egypt during two consecutive
winter seasons of 2016/2017 and 2017/2018, to investigate the effect of the foliar spray of kaolin
(Aluminum phyllosilicate [Al2Si2O5 (OH)4]), by concentrates at 1 and 1.5% as well as control with
different protection application treatments (control, palm trees leaves siege, low tunnels covered by
white shade net and low tunnels covered by black shade net) on growth, early yield and total yield of
frigo strawberry transplants (Festival cv). Cultivation of strawberry under low tunnels covered by
black shade net or under palm trees leaves siege produced the highest plant fresh weight, early and
total yield of strawberry fruits compared with control or low tunnels covered by white shade net
which gave the lowest values. Kaolin sprays at 1 % gave the best growth, early and total yield
followed at 1.5 % compared to control treatments. The study summarized that, cultivation of
strawberry transplants under low tunnels covered by black shade net with 1% sprays of kaolin can be
succeed to protect strawberry plants and enhancement growth and yield under Siwa Oasis conditions.
