KOMBINOVANA PRIMENA PLODOREDA I HERBICIDA ZA UNAPREĐENJE SUZBIJANJA KOROVA U KUKURUZU

Abstract

Maize cultivation in a crop rotation, especcially when legumes are incorporated, contribute to the high yield achievement and a reduction of weed infestation. In such a crop rotation system, the lower rates of herbicides could be applied in order to achive reduction of weed species distribution. The investigations were aimed to underline the importance of crop rotation in comparision to maize continuous cropping for weed distribution reduction and increase of maize leaf area and grain yield. The results of long-term investigation showed that crop rotation contibuted to the significant decrease of weed number (51,19%) and increase of leaf area and grain yield of maize (13,98% and 45,87%, respectively) in comparision to maize continuous cropping. Differences in weed number, maize leaf area and grain yield between herbicide treatments in the recommended and half of recomended rate were not significant, underlining the importance and high efficiency of combined application of cultural and chemical measures in maize cultivation and agroecosystem prevention.
