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.
P did not cause any significant influence on growth or yield of vines and tubers in either cultivar.
