IMPACT OF SOME HERBICIDES ON THE CHEMICAL COMPOSITION OF POTATO TUBERS
Krystyna Zarzecka, Barbara Għsiorowska
The 3-year field experiment researched the impact of weed control with herbicides on the chemical composition of four table potato cultivars. There were observed significant changes in the tuber chemical composition of potatoes treated with herbicides which significantly decreased the contents of dry matter, starch and phosphorus as well as increased the contents of vitamin C, total saccharides and magnesium in tubers, as compared to the object weed-controlled mechanically.
Key words: potato, herbicides, starch, vitamin C, reducing saccharides, total saccharides, potassium, phosphorus, magnesium.
