Abstract:Sweet potato (Ipomoea batatas (L.) Lam.) has a potential to become a new field crop for higher latitudes. Sweet potato was cultivated for the first time in the fields of Estonia. During the study, the photosynthetic characteristics and yields of sweet potato cultivars 'Evangeline' and 'Covington' were investigated under fertilisation with two nitrogen (N) rates (0 and 100 kg ha −1 N) and various fertilisers in 2018, 2019 and 2021. Variation in fertiliser rate and composition had no effect on CO 2 assimilation … Show more
