Abstract
Under certain nutrient solution management practices in hydroponic systems, sweetpotato [Ipomoea batatas (L.) Lam.] plants can exhibit excessive shoot growth and reduced storage root yield. An experiment was conducted which compared sweetpotato production in nutrient film technique (NFT) systems either with daily nutrient solution replenishment + real-time pH control or with nutrient solution replenishment 3-times per week + periodic pH adjustment. Results showed that replenishment of nutrient solution on a daily basis produced excessive foliage growth with very little storage root production. Nutrient solution replenishment 3-times per week produced manageable vine growth and respectable storage root yields.
