Evaluation of sweet potatoes at several times of planting

Abstract

From 1980 and 1982 a high yielding sweet potato cultivar L0-323 was assessed across seasons of planting to determine production of vines, storage roots and starch. The influence of precipitation and soil temperature was monitored. Leaf and vine dry matter yields were highest from November planting at 10.25 t/ha and least from March planting at 2.68 t/ha. Highest storage root dry matter yield occurred from May planting at 15.16 t/ha and least from March planting at 7 .89 t/ha.
