Summary: | A line-source irrigation design was used to provide continuously increasing amounts of irrigation at each application to sweetpotato [Ipomoea batatas (L.) Lam]. Marketable yields increased with applied irrigation amounts until a total water application of 76% of pan evaporation (E(pan)) was reached and then decreased rapidly with applied irrigation amounts. Weight loss and decay of roots during storage showed quadratic responses to irrigation amounts and were minimal at the irrigation level of maximum yields. Contents of dextrins and maltose increased with irrigation amounts. Glucose content was maximum at a total water amount of 94% E(pan), and fructose content decreased with increased amounts of irrigation. Sensory ratings for appearance, flavor, texture, and preference, and objective color measurements of cooked flesh also reached their highest values near the irrigation amount of maximum yield |
