The study looked at different ways to grow sweetpotato seedlings to see which method worked best. They tested using mulch and not using mulch in big and small sheds. The results showed that using mulch made the seedlings grow faster and have more seedlings, but they were slightly lighter. Overall, the best method was using mulch in a big shed. They also found that one variety of sweetpotato grew faster and had more seedlings than the others.
