Abstract
In 2001i2002 & 200219003 seasons. mature Alphonse mango trees received 4 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%. GA; 10 ppm 4» urea. GA; 20 ppm + urea. PBZ 500 ppm + urea and PBZ 1000 ppm+ urea. GA3 at both tested concentrations, withfor without urea, tended to increase number of fruits retained till harvestrpanicle. number of harvested fruitsrtrees, the yield f tree. the hypothetic yieldffed. and TSSr'acid ratio in the pulp juice. In addition. the treatments implying PBZ failed to affect significantly number of fruits/tree, the yield (per treelor fed}, physical fruit characteristics and chemical constituents of the pulp juice.
