Treść
The research material consisted of tubers of two potato cultivars in a three-years field experiment conducted at the Zawady Experimental Station (52?03'N; 22?33'E) of the University of Natural Sciences and Humanities in Siedlce. The experiment was a split-plot design with three replication. The effect of two factors was evalated: I - two potato cultivars (Irga and Balbina), II - four weed control methods: 1) mechanical weed control alone as a control variant; 2) combined mechanical and chemical weed control, including ridging and harrowing and twice ridging before potato emergence and treatment with herbicide Plateen 41.5 WG (metribuzin + flufenacet), at a dose of 2.0 kg ha-1 , immediately before the emergence of potato plants; 3) combined mechanical and chemical weed control, comprising single ridging and treatment with herbicide Racer 250 EC (fluorochloridone) applied at a dose of 3.0 dm3 ha-1 up to 10 days after planting of potato tubers; 4) combined mechanical and chemical weed control, including ridging and harrowing and twice ridging before potato emergence and treatment with herbicide Sencor 70 WG (metribuzin), dosed 1.0 kg ha-1 , immediately before the potato emergence. The work was aimed to determine the effect of herbicides on the content of dry matter, total sugars and reducing sugars in the potato edible tubers. Herbicides application at potato cultivation, as compared to mechanical cultivation (as control variant), contributed to the increase total sugars and reducing sugars. The highest macronutrients content was determined in the tubers of potato sprayed with Plateen 41.5 WG and Racer 250 EC. The concentration of dry matter and reducing sugars in potato tubers was significantly affected by the cultivars and weather conditions during the growing season. Weed control chemicals increasing an accumulation of total sugars and reducing sugars may lead to excluding potato from processing into chips and crisps.
