Abstract
Sweet potato ((Ipomoea batatas L.) is a high-yielding nutritious specialty crop. There is a growing need for proactive information on sustainable production of sweet potatoes under short growing seasons. The objective of our study was to evaluate the effects of crop residue and synthetic mulches on the growth, yield, and quality parameters of three varieties of sweet potatoes. Three types of mulch, wheat straw (straw), white polyethylene film (white mulch), and black plastic film (black mulch), and a control (no mulch) were evaluated during the 2021 and 2022 growing seasons in the south-eastern region of Kazakhstan. The vine length, meristem number, tuber per plant, and tuber weight were significantly higher under white mulch and black mulch than under straw, and the results were significantly different from the control. The total yields of sweet potato tubers under white mulch and black mulch also varied significantly among the varieties, ranging from 20.5t/ha for Rizi 0603 to 54.5t/ha for Xushu 25. The results of the present study will be used to develop other technological sequences for the cultivation of sweet potatoes in the south-eastern region of Kazakhstan. More research is needed to ascertain the stability of the effects of varieties, mulch treatment, and their interactions on yields and to determine other treatments and varieties with better potential to improve sweet potato yields for cultivation in Kazakhstan.
