In our investigation we used different weed control technologies in the different phenology states of the maize. The experiment have been
carried out in Hódmezővásárhely, in the Experiment garden of the Pilot farm of University of Szeged Faculty of Agriculture, on meadow
chernozem soil, on 24 m2 plots, in 3 replications, randomized blotch design. The experiment can be regarded as 15 weed-control strategies
where, in addition to the untreated control, six chemicals or chemical-combinations are applied (Spectrum 720 EC, Motivell Turbo D,
Stellar + Dash HC, Clio + Akris SE + Dash HC, Clio + Dash HC) in five different times (pre, early post, post and two late post) and eight
mechanical weed-control technologies were used. Hoeing took place connected to the herbicide treatments in different times: until 2-3-leave
age weedless, in 3-4-leave age hoed once, from 3-4-leave age weedless, in 6-7-leave age hoed once, from 6-7-leave age weedless, in 8-leave
age hoed once, from 8-leave age weedless.
Our results were assessed by chemical efficiency examination, maize length measurement, corncob-length and fertility examination,
Sorghum plant-number determination and yield weighing carried out in four periods. The data were evaluated by a one-factor analysis of
variance and a two-factor linear regression analysis.
