Abstract: An experiment was conducted to determine the effects of repeated application of a cytokinin, N- (Phenylmethyl) -lH-purine 6 amine, on the growth and yield of "Red Creole" onion (Allium cepa L). Results showed detrimental effects of the cytokinin as the application frequency was increased. No significant difference was found between control plants and those sprayed with the cytokinin at rates 100 or 200 ppm 15 days after transplant, but in these treatments growth and yield were significantly higher than in plants sprayed every 15 days after transplanting. Treatments every 7 days after transplanting gave results significantly lower than the other frequencies. These results show that the application of this cytokinin to "Red Creole" onion at rates 100 or 200 ppm did not promote growth or yield, and that repeated treatment actually decreased overall growth and yield.
