Özet

The Central Anatolia region is an important rainfed region in Turkey. Wheat-fallow cropping system has been traditionally practised in the region. The purpose of this study was to identify the optimal tillage methods and N levels in a wheat-chickpea (Cicer arietinurn L.), wheat-fallow and wheat monoculture in dryland farming. 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 four 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 and yield components 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. Although the effect of increasing N levels was unclear, 100 or 150 N kg ha(-1) is recommended in the region for wheat. Results indicated that conventional tillage, wheat-chickpea rotation and 100 to 150 N kg ha(-1) for wheat would be recommended for the region.
