Abstract
The paper presents the results of calculations which are 3-year field experiment with different weed control methods in the cultivation of edible potato. Experimental objects included five weed control methods: control object – mechanical as well as four objects of mechanical-chemical treatments with the use of herbicides and their mixtures - Command 480 EC, Command 480 EC + Afalon Dyspersyjny 450 SC, Stomp 400 SC, Stomp 400 SC + Afalon Dyspersyjny 450 SC. The economic analysis included performed treatments and material input. The economic effects of crop protection treatments was determined on the basis of the indicators adopted in crop protection, such as: index of the cost defrayal (WPK) and orientation indexes of profitability (E1 and E2). Orientation indexes of profitability E1 and E2 showed that mechanicalchemical protection of edible potato using herbicides was profitable.
