Length, nodes underground, and orientation of transplants in relation to yields of sweet potato

Length, nodes underground, and orientation of transplants in relation to yields of sweet potato

1986

A:PS

Total marketable root yield was greater with 40- to 45-cm rather than 20- to 25-cm lengths of `Red Jewel` sweet potato [Ipomoea batatas (L.) Lam.] transplants. U.S. #1 root yield from 20- to 25-cm `Red Jewel` transplants was increased when they were oriented vertically, but there was no difference in the percentage of U.S. #1 root yield under these conditions. Orientation did not influence significantly U.S. #1 root yield from 40- to 45-cm `Red Jewel` transplants, but the percentage of U.S. #1 roots increased due to horizontal orientation. When `Red Jewel` transplants were oriented vertically, their length did not affect U.S. #1 root yields. With horizontal orientation, U.S. #1 root yield of 40- to 45-cm `Red Jewel` transplants increased. Yield of U.S. #1 roots of `Georgia Jet` was not affected by transplant length or orientation but was reduced when 5 or 6 nodes were planted underground. [AS]
