ABSTRACT
A field experiment was conducted in 2012 to 2013 to determine the effect of tillage, including deep strip tillage, shallow strip tillage and conventional tillage, and weed control method (untreated control, mechanical, chemical) on weed infestation of maize planted after winter cover crop being intended for silage. Strip tillage was executed with the use of a universal active tool for the strip tillage and mechanical interrow cultivation. Cultivated straps were 25 cm wide and 20cm deep at deep strip tillage, and 25cm wide and 3-5cm deep at shallow strip tillage. Conventional tillage was performed with moldboard plow at a depth of 20cm. Strip tillage significantly reduced weed biomass in maize as compared to conventional tillage. Weed biomass and density after mechanical and chemical treatment was similar and significantly lower than at untreated control. The new developed active tool for the strip tillage and mechanical interrow cultivation ensures a good efficiency of weed control in maize planted after winter rye cover crop.
