Prognostic of Yield of Potatoes of Promising Domestic Varieties Under the Impact of Stress Abiotic Factors
Year: 2023
Type: article
Abstract: Twenty four potato varieties (Solanum tuberosum L.) differing in ripening groups (early, middle-early and mid-season-ripening) were studied. Potatoes were grown in the conditions of the Middle Volga region of Russia. It was found statistically that the yield (t/ha) of early and mid-season-ripening varieties was negatively correlated with the increase in average temperatures during the growing season from May to August (R = –0.97, P = 0.04). Soil moisture content at a depth of 20 cm was positively correlated with the yield of middle-early varieties (R = 0.97, P = 0.04). A soil moisture content increase was beneficial to average tuber weight (R = 0.98, P = 0.04), but only in the middle-early and mid-season-ripening groups. However, the soil moisture content and the tuber numbers in mid-season-ripening varieties had a negative correlation (R = –0.96, P = 0.05).
