“…Weed competition affects physiological processes in maize plants and modifies their morphology. It affects their light use efficiency and physiological processes relevant for productivity, such as chlorophyll and carotenoid contents (Spasojević et al, 2014). Plant canopies can be structurally characterized by their harvest and leaf area index.…”

Zemdirbyste-Agriculture, 107 (1): 33-40. AbstractThe effects of different measures within maize cropping technology, aimed to suppress weeds as a part of integrated weed management (IWM) system, are analysed and evaluated in this manuscript, in line with the results of longterm experiments. For sustainable maize (Zea mays L.) production, implementation of IWM system aiming to reduce reliance on chemical weed control within Europe is a key priority. This IWM system includes all possible solutions, such as preventive, direct, biological, mechanical and alternative measures. A cropping system approach is essential to manage weeds, utilize genetic potential of maize genotypes and reduce yield losses due to weed competition. Long-term experiments are nowadays rare, but they are an excellent and reliable method for comparing cropping systems regarding yield and reduction of weed infestation level. In the research program implemented at the Maize Research Institute Zemun Polje in Central Serbia, the effects of different cropping measures and their interactions as a part of IWMs were studied during ten years. Maize rotations with winter wheat (Triticum aestivum L.) and soybean (Glycine max (L.) Merr.), combined with herbicide application, showed the best effect on weed biomass reduction, 92.1% and 92.2%, respectively. Winter wheat was a better preceding crop for maize than soybean, especially in combination with herbicides applied in recommended as well as in half of recommended rate. Intensification of soil tillage significantly reduced maize weed infestation, especially abundance of perennial species: Johnson grass (Sorghum halepense (L.) Pers.), Canada thistle (Cirsium arvense (L.) Scop.) and field bindweed (Convolvulus arvensis L.). Other measures, such as type of fertilizer, maize row space and crop density, cover cropping and intercropping also affected weed biomass production in maize fields. Maize growing with reduced row spacing contributed to weed biomass reduction by 27.4%, while application of slow-release urea contributed to crop competitiveness. Weed biomass in sweet maize (Zea mays L. convar. saccharata) grown with common vetch as a cover crop was significantly reduced (48.5 g m -2 ) compared with the treatment without a cover crop (564.3 g m -2 ).

An experiment was set up in Maize Research Institute Zemun Polje, Serbia in 2009. Two cropping systems, maize continuous cropping and maize-winter wheat rotation, included subtreatments with different weed management: control without herbicide application and application of the herbicides isoxaflutole + acetochlor at the recommended dose (RD) and half of recommended dose (0.5 RD). After three and five years of experiment, maize harvest index, leaf area index (LAI), chlorophyll and carotenoids content as parameters of maize competitiveness, and weed biomass as parameter of weed abundance, and their interdependences were analyzed. Weed biomass was significantly decreased by herbicide application in both years and cropping systems, but there was no significant differences between recommended and half of recommended dose. The average weed biomass for all herbicide treatments was 33.73% lower in maizewinter wheat rotation than in maize continuous cropping. Parameters of maize competitiveness have been changed according to the level of herbicide application and to a greater extent in maize continuous cropping than in the maize-wheat rotation.
