Abstract: Initiation of sweet potato [ Ipomoea batatas (L.)] plant harvests from the propagating bed was later from the sparse plant producer ‘Georgia Jet’ than from the profuse plant producer ‘Georgia Red’. Also, the initiation of plant harvests from storage roots cut into longitudinal halves for inspection of internal quality before bedding was later than from whole roots. These differences were reflected in lower cumulative percentages of total plants harvested from ‘Georgia Jet’ than from ‘Georgia Red’ within 2 weeks and from longitudinal halves within 2 and 4 weeks after initiation of plant harvests. Total plant production was greater from whole than from halved ‘Georgia Jet’ roots. Total plant production was greater from halved roots immersed in Botran 75W compared to those immersed in calcium hypochlorite. Cutting and immersion treatments did not influence total plant production from ‘Georgia Red’, a profuse plant producer. ‘Georgia Jet’ roots deteriorated more than ‘Georgia Red’ in the propagating bed, and deterioration was increased by cutting and immersion in calcium hypochlorite. Presprouting did not reduce deterioration of roots in the propagating bed, but did reduce the number of days from bedding until first plant harvest. It also increased the cumulative percentage of the total plants harvested within 2 and 4 weeks after harvests were initiated and increased total number of plants produced from both small and large ‘Georgia Jet’ roots and from large ‘Georgia Red’ roots. Large roots of each cultivar produced more plants than were produced by small roots when presprouted. Large roots of ‘Georgia Jet’ also produced more plants than were produced by small roots when not presprouted, but root size did not influence total plant production from ‘Georgia Red’ roots that were not presprouted. Chemical name used: 2,6-dichloro-4-nitroaniline (Botran 75W).
