Abstract:

A study was conducted to investigate the effect of phosphorus fertilizer levels on the growth and tuberization of two sweet potato cultivars. P did not cause any significant influence on growth or yield of vines and tubers in either cultivar. Cv. I (Musinya) produced significantly longer and a higher yield of vines than cv. II (Gikanda), but the latter produced a significantly higher yield and number of tubers than the former. There was no significant difference in dry matter accumulation in the tubers of both cultivars at all P levels and the control. However, cv. I accumulated significantly higher dry matter in the vines than cv. II, whereas cv. II accumulated significantly higher dry matter in tubers than cv. I during both seasons but P fertilization did not influence the accumulation.
