Effect of Agrotechnical Measures on Chemical Composition of Early Potato Tubers

<title>Abstract</title> Potatoes hold a significant position as one of the most important crops. Their value lies not only in their nutritional composition but also in their function as raw materials for various processing purposes. Furthermore, the cultivation of early potatoes carries considerable agrotechnical importance due to their ability to serve as the initial crop in intensive crop rotation, optimizing the utilization of agricultural soil. The primary objective of its production is to reach a consistent and high yield of premium quality. Additionally, the aim is to enter the market as early as possible and maximize profitability. To achieve these goals, producers utilize specific agrotechnical measures such as mulching and plant covering to ensure earlier and safer production, thus maximizing profits. Our research aimed to determine the impact of different agrotechnical measures (biodegradable mulching, agrotextile, low tunnel) on the chemical composition of early potato tubers. A three-year field experiment was managed in Begeč with two early potato cultivars, Cleopatra and Riviera. The tested agrotechnical measures significantly influenced the quality of early potatoes, hence the increase in the content of dry matter, starch, vitamin C, cellulose, and ash in the tubers and on reduction of sugar and nitrate content.
