In comparative stationary field experiments performed in Apahida, Cluj County, during four years (2005-2008), cabbage, sweet corn, carrot and garden bean crops have been followed on two different tillage systems: a conventional system - 5-6 tillage works including deep ploughing (25-28 cm deep) and 2-3 weeding, and the minimum tillage system: the strip-tillage cover crop system (spring fodder=oat+vetch) that was treated with Glyphosat herbicide (2 l/ha) and remained on the ground as mulch on which 10-15 cm wide sowing strips were split open. With the minimum tillage a 3-5 day delay in plant sprouting was noticed and vegetation was prolonged for few days in sweet corn, carrot and bean. Yield decreases by the minimum tillage vary between 7.7% and 16.7% in carrot and 5.0% and 10.9% in garden bean. In cabbage and sweet corn yield decrease was stated only during the first 2 years, while during the last 2 years the crop would balance on the two tillage methods. There was some product quality decrease with the minimum tillage, especially in carrots and beans.
