Abstract :Optimum tillage depth for sunflower after wheat was studied on Brown soils at two locations in Central Anatolia. The experiments were constituted as split randomized blocks with three replications, the treatments were 9-11, 14-16, 19-21 and 24-26 cm tillage depths. Weeds were permitted for growing in the half of every plot in order to test their adverse effect on sunflower yield. Optimum tillage depth under the research conditions was 14-16 cm from the points of economy and yield. Weed infestation significantly decreased the sunflower yield.
