Observations in Time of Maturity of Sweet Potato (lpomoea Batatas (LAM.))

Abstract

To observe development of a sweet potato crop, a technique using successive row by row  harvesting of plots was used. Comparisons were made of various crop characters on the one soil type with varied pre-crop histories. It was found that as the soil tended to exhaustion low yields were obtained, resulting from reduction in both number and size of tubers and that maxima in crop yield, number of tubers and flowers occurred earlier than in less depleted soil. It was shown that maximum flowering is a useful indicator of time of achievement of maximum yield.
