Effect of tillage and crop rotation on weed infestation in maize

The aim of this study was to determine the effect of different tillage and crop rotation on weed infestation in maize. The observation was made at the experimental site in Zabcice, which belongs to corn production areas, in 2013 and 2014. The soil was treated in two variants. The first option was the traditional method of tillage (plowing). The second variant was shallow tillage to a depth of 0.05 m (minimum tillage). Crop rotation was another factor influencing weed infestation of maize (maize monoculture, Norfolk crop rotation). The obtained data were evaluated by multivariate analysis of ecological data. Different variants of tillage and crop rotation affect the occurrence and number of certain species, it follows from this analysis. The experimental results show, that the lowest weed infestation was on the variant of maize monoculture. Lower infestation was on the variant with traditional tillage.
