Abstract : In 1993 and 1994, the effects of KNO3 (at 24, 36 or 48 g/litre, applied in 3 split doses in September, October and November) or paclobutrazol (at 0, 2.5, 5, 10 or 15 g a.i./tree) applied to 5-year-old mango cv. Haden trees at Maracay, Aragua State, Venezuela, were investigated. Paclobutrazol was applied in July (except for paclobutrazol at 2.5 g/tree which, in 1993, was applied in October). Control trees exhibited low yields and strong biennial bearing. KNO3 application (36 or 48 g/litre) advanced flowering and harvesting date, increased yields and reduced alternate bearing. Paclobutrazol application at 10 or 15 g/tree increased yields and reduced alternate bearing.
