| Abstract | ||||
| This study was carried out during two successive seasons (2010 and 2011) on fourteen years old Banati guava trees (Psidium guajava L.), grown in sandy soil in the South of Tahrir region at Aly Mubarak Research Station. GA3 at 300 or 400 and 500 ppm was sprayed once time at full bloom, hand pollination with pollens from Malizi and Gizi guava trees for Banati guava trees as well as branches bending were carried out. The obtained results revealed that most treatments especially those included GA3 sprays improved the yield and fruit quality. However data proved that GA3 sprays at 400 ppm were more effective in increasing number of fruit set/ meter and fruit set and subsequently improved the yield as well as the physical fruit characteristics. Hand pollination with pollens from Malizi guava tree for Banati guava trees significantly increased total acidity and Vitamin C. Branches bending had the highest percentage of total sugars. So, spraying 400 ppm GA3 one time at full bloom was the promising treatment for increasing productivity of low yield Banati guava trees grown under sandy soil condition. | ||||
