| Abstract: the objective of this work to study the influence of folair application of boric acid and calcium nitrate on friut set and yield of seewy date palm cultivar growing in El dakhla Oasis newvalley covernorat during two successive seasons (2021 , 2022 ) , palms were treated with different rates of boric acid ( zero rate , 125 , 250 and 500 ppm ) and sprayed with calcium nitrate at rates (zero rate, 1% ,2% and 4%) , during two growing seasons results showed that the persentage of fruit set and fruit retention and Total yield response to boric acid and calcium nitrate treatments, all studied treatments results insignificant increase in fruit set and Total yield compared with the control treatment in both experimental seasons, the best results concerning fruit set and Total yield were obtained by sparying boric acid at (500 ppm) mixed with calcium nitrate at rates (2%) in both seasons, on the contract the lowest fruit set and Total yield were recorded by control treatment in two experimental seasons |
