Abstract
Effects of Paclobutrazol and KNO3 on the induction of Cassava (Manihot esculenta Crantz) flowering were observed. Two experiments were set up. In the first experiment paclobutrazol was sprayed through plant leaves in five concentrations consisted of 0, 250, 500, 750, and 1,000 ppm. The second experiment was set up to investigate the effect of paclobutrazol applied through the soil with two concentrations consisted of 0 and 500 ppm and KNO3 with concentrations of 1%, 2%, and 3% applied through the leaves. The results showed that 500 ppm Paclobutrazol reduced the vegetative growth and it was effective in stimulating flower. Additionally, Paclobutrazol applied through the soil did not affect the flower induction. There is no interaction effect between Paclobutrazol and KNO3 on the vegetative growth and induction of flower.
