Özet

The aims of this study were to determine how the tillage system and residual N of soil affected chickpea yield and its trait in rotation with wheat under Central Anatolia Region. In this study, two tillage methods viz. conventional and reduced tillage, three crop rotations; wheat-wheat; wheat-fallow; wheat-chickpea and four N levels of 0, 50, 100, 150 kg ha(-1) were evaluated for four years duration (2012-2015). Tillage methods were maintained into main plots, crop rotation into subplots and N levels into sub-sub plots. Only chickpea in continuous rotation with wheat was examined in this study. The results were evaluated according to split plot design with three replicates. Grain yield was higher under conventional tillage (CT) than reduced tillage (RT) in both of the growing seasons. Some important yield components were higher under RT than CT especially in the second growing season. These differences of tillage methods may also be due to climatic conditions. Residual fertilizer N significantly affected chickpea grain yield which increased with 100 and 150 kg N ha(-1) levels. Results also indicated that; conventional tillage may be more appropriate for chickpea in rotation with wheat. Chickpea grain yield was also affected when N fertilizer applied to wheat.
