DIVERSITY OF WEED SPECIES FROM MAIZE CROP AND IT’S IMPORTANCE FOR NEW ECOLOGICAL WAYS

Rezumat

Being a plant cultivated maize frequently becomes weedy at levels considered dangerously high. The plant, having requirements especially for water, benefits to the greatest extent from the segetal species, namely from the "summer" group. The determinations regarding weed species targeted areas cultivated with maize on private farms. The inventories carried out under these conditions are becoming important today, both for the perspective of weed conservation from an ecological perspective, and as their effective response to the control methods that are taken. The determinations resulted in a total of 22 species. Of these, 13 were part of the annual dicotyledons, 6 were perennial dicotyledons and 2 species were annual monocotyledons. The entire plant spectrum was part of 13 botanical families, the best represented being Poaceae. The species were then grouped according to density and constancy, and under these conditions the dominant species was Echinochloa crus-galli L./P. Beauv. With the help of this data, appropriate decisions can be made to control the entire weed spectrum in maize, especially for the dominant ones. The inventory of weeds in maize thus also acquires a clearly practical character, with the help of which some levels of economic control-fighting intervention are also established.
