| Abstract : | A field experiment was carried out in 2008-2010 at the Zawady Experimental Station, Chair of Plant Cultivation, University of Natural Sciences and Humanities in Siedlce. The experiment was set up in the split-plot design as a two-factorial three-replication trial. The factors examined were as follows: factor I – potato cultivars Cekin, Satina, Tajfun, factor II – herbicides (Command 480 EC, Command 480 EC and Afalon Dyspersyjny 450 SC, Stomp 400 SC, Stomp 400 SC and Afalon Dyspersyjny 450 SC), and control treatment – mechanical weeding. It was demonstrated that the application of mechanical-chemical treatments including herbicides and their mixtures contributed to a limiting effect on weed infestation in potato crop. Statistical analysis showed that yield of potato tubers strongly depended on the cultivar, weed control method applied, and the weather conditions in the vegetation periods. For agricultural application, mechanical and chemical weed control is recommended with a double herbicide treatment (before and after emergence) and mechanical and chemical weed control with a mixture of herbicides, before potato emergence. |
