To investigate the effects of weather conditions on the yield and starch content of sweet potato storage roots, Pearson's coefficients of correlation were calculated using the data of sweet potato breeding experiments at the Miyakonojo Research Station from 1989 to 2016 (cultivars Koganesengan and Shiroyutaka) and the monthly average of daily weather data (mean temperature (MT), highest temperature (HT), lowest temperature (LT), rainfall (RF), and sunshine duration (SD)) during the sweet potato cultivation period of (May to October). The yield in non-mulching culture conditions correlated positively with HT in all months during the cultivation period and with SD in June to August, but correlated negatively with RF in June to August. These results suggest that higher air temperature throughout the cultivation period and fine weather during the rainy season and the summer season increased the yield. Meanwhile, the yield in mulching culture conditions correlated positively with HT in May and August to October, but correlated negatively with RF in August, suggesting that weather conditions in the early and late growth stages are important. Starch content correlated positively with SD in August in the non-mulching culture, but correlated negatively with LT in August in the mulching culture. Multiple regression analysis using principal components derived from weather data as explanatory variables suggested that more than 60% of the annual variation in both yield and starch content can be explained by variation in weather conditions, except for the cultivar Shiroyutaka in the mulching culture, for which less than 50% was explained by the weather conditions.},
