Popis: Four bed covers (black polyethylene, perforated clear polyethylene, double-slitted clear polyethylene, and spunbonded polyester) and a bare soil control were evaluated for their effect on the number, size, and harvest time of sweetpotato [Ipomoea batatas (L.) Lam. cv. Travis] transplants. The perforated and double-slitted bed covers increased the weight and number of sweetpotato transplants compared with the control or with black polyethylene at the first harvests in 1986 and 1987. Seed roots covered with the spunbonded polyester bed cover produced more plants of greater weight than seed roots covered with bare soil at the first harvest in 1986 only. Black polyethylene treatments produced the greatest weight and number of transplants at the second harvest (8 to 12 days later) in both years. There were no significant differences in total weight and numbers of transplants among black polyethylene, or perforated or double-slitted clear polyethylene treatments in 1986. Total transplant count and weights from plots covered with spunbonded polyester were lower than those from plots with any other bed covers.
