During the growing season in the period from 1996 to 1999, effects of irrigation and applied herbicides on the level of weed infestation and yield parameters of maize were studied. Weed infestation was expressed through the number and the weight of weeds per square meter. The plant height, leaf area, leaf area index and grain yield were observed in maize. Weed infestation of maize differed depending on the application of both, irrigation and herbicides. The lowest, i.e. highest weed fresh weight was recorded under rainfed conditions and the application of herbicides (546.0 g/square meter), i.e. on the untreated area under irrigation conditions (2573.1 g/square meter), respectively. All investigated parameters of competitiveness and yielding of maize had statistically very significantly higher values under conditions of irrigation and the application of herbicides than under rainfed conditions without application of herbicides in all years of investigation.
