The purpose of this study was to identify the optimal tillage methods and N levels in a wheat-chickpea (Cicer arietinum L.), wheat-fallow and wheat monoculture in dry farming areas. In this study, two tillage methods (conventional and reduced tillage), three crop rotations (wheat-wheat; wheat-fallow; wheat-chickpea) and four N levels (0, 50, 100, 150 kg ha(-1)) were evaluated in Central Anatolia Region for 4 year. The experimental design was split-split-plot with three replicates. Tillage methods were in main plots, crop rotations in subplots and N levels in sub-sub plots. Conventional tillage methods resulted in higher grain yield compared to reduced tillage. Four years is certainly not long enough to reveal the full effects of the crop rotation, but wheat-chickpea rotation provided an alternative to wheat-fallow cropping system in the region. Increasing nitrogen doses increased plant height, head length, biological yield and grain yield. Results also indicated that; using conventional tillage with wheat-chickpea rotation and 100 to 150 N kg ha(-1) for wheat would be recommended for wheat production in the region.
