| Abstract | ||||
| The present work was carried out to study the effect of GA3 at 50 and 100 ppm, urea at (0.5 and 1.5%) and pinching early flowering on growth of Zebda mango trees grown in the experimental orchard of El-Kassasin Horticultural Research Station, Ismailia Governorate, Egypt. The results indicated that different treatments of GA3 or urea each alone or in combination with pinching both of delayed panicle emergence and full bloom, but increased number of fruits at harvest and yield/tree. Data also revealed that the same treatments promoted shoot length and number of leaves/ shoots without pinching. While, these treatments tended to increase the number of healthy panicles and total number of panicle/tree, while obviously depressed number of malformed panicle/tree and malformation percentage. From this study it could be recommended to spray "Zebda" mango trees once at mid November with GA3 at 100 ppm with pinching early flowering in the winter. Since, this treatment was the most effective enhanced vegetative growth which in term increased the yield of the trees. | ||||
