Abstract :

To study the effects of tillage methods on yield and its components of wheat cv. N-80-9, an experiment was conducted using randomized complete block design with four treatments including  moldboard +  disk, disk, chisel + disk and rotivator + disk with four replications in  Aliabad- Katool in Golstan Province in two cropping seasons (2009-2010). Yield and yield components were affected by tillage methods, significantly. The highest yield was obtained in moldboard + disk and rotivator + disk in 2009 and moldboard + disk and two time disk and rotivator + disk in 2010. Whereas, common tillage (moldboard + disk) in comparison with preservative tillage methods not only consumed high energy and additional time, but also caused more erosion using mechanical tools and consequently led to more expense, the conservational methods are recommended instead of costume tillage methods.
