ABSTRACT

A study was carried out to investigate the effect of pre-harvest vine removal on the quality and postharvest behavior of sweet potatoes. Tuberous roots (tubers) of sweet potato cv. ‘Tripti’ were harvested at 150 days after planting in which top vines were removed 0 (control), 4 and 8 days before harvest. Removal of vines 4 and 8 days before harvest increased the dry matter content and free sugars of the tubers. Conversely, a loss of starch on dry weight basis was noticed. Tubers from these treatments sprouted earlier, infested by sweet potato weevll and thus could not be stored for longer period.
