Abstract : The individual and combined effects were determined of a single KNO3 spray (at 80 g/litre) and shoot decapitation on Haden (monoembryonic) and Manila (polyembryonic) cultivars. Mature vegetative shoots were treated in January during flowering. The % flowering shoots was highest in both cultivars with spraying alone, but spraying + decapitation tripled and nearly doubled the number of panicles/shoot in Haden and Manila, respectively, compared with the untreated controls. Fruit set was always markedly better in Manila than in Haden. With Manila, KNO3 spraying alone produced twice as many fruits/shoot or /panicle as in the other treatments. Fruit size and quality were not affected by increased fruit set.
