The content of total sugars and reducing sugars in potato tubers is one of the most important quality features determining the suitability for direct consumption and for processing into food products. The objective of the study was to determine the effect of the soil conditioner UGmax on total sugars, reducing (simple) sugars and sucrose in potato tubers. Experimental material consisted of tubers of second early table potato grown in a field experiment conducted in central-eastern Poland.

Following chemical analyses, statistical calculations were performed and they demonstrated a significant effect − an application of the soil conditioner UGmax contributed to an increase in the tuber content of reducing sugars compared with control potato tubers. The highest simple sugar content was found after three applications of the soil conditioner at the rate of 1.0 and 2.0 dm 3 ha -1 . The remaining carbohydrates determined in the study did not respond to UGmax application. Cultivars grown in the study differed significantly in terms of reducing sugar content only, more sugars being accumulated by Tajfun rather than Satina.
