This experiment was carried out to verify the influence of a roller after wheat sowing under corn stover, in two farming areas. The variables studied were: plant population 15 days after seedling, population with cobs, grains per cob, 1000 seed weight, yield and the economic viability of the operation. The significant increase of emerged plants after the usage of a roller didn't reflect in the yield components. Therefore it's not recommended in experimental conditions.
