Effect of strip tillage and mechanical weeding on yield of silage maize planted after winter cover crop

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 growth and yield of maize planted after winter rye cover crop. Strip tillage was executed with the use of a universal active tool for the strip tillage and mechanical inter-row cultivation. Cultivated strips were 25 cm wide and 20cm deep at deep strip tillage, and 25 cm wide and 3-5 cm deep at shallow strip tillage. Conventional tillage was performed with moldboard plow at a depth of 20cm. Strip tillage provided maize yield similar to that of conventional tillage. Yields obtained after mechanical end chemical weed control were similar and significantly higher than at untreated control. The new developed active tool for the strip tillage and mechanical weeding provides good conditions for planting and growth of maize planted after winter rye cover crop.
