In 2001! 2002 and 2002(2003 seasons. mature Alphonse mango trees received 4 toliar sprays at monthly intervals from mid Oct. to mid Jan. The tested treatments were : Cont. ( water). GA; (alone) at 10 ppm, 6A3 ( alone) at 20 ppm , Paclobutrazol (PBZ) (alone) at 500 ppm , PBZ (alone) at 1000 ppm, urea (alone) at 1%. GA310 ppm + urea 1% . GA; 20 ppm + urea 1% _ PBZ 500 ppm + urea 1% and PBZ 1000 ppm + urea 1 %. Clear responses in vegetative growth , expressed as shoot growth‘rate, number of leaves! shoot. leaf area and leaf fresh and dry weights was obtained by all treatments implying (3A3, urea or both. However, the most effective treatment was (GA; 20 ppm + urea 1%) . The leaf content of chlorophyll a a b . carotenoids, nitrogen. phOSphoms and potassium were not altered by any of the tested treatments, except for the increment of leaf N91: in the first season by PBZ 1000 ppm + urea 1% as well as in K % in the second season by PBZ 1000 ppm (with l or without urea ) and PBZ 500 ppm + urea 1%.
