AbstractA field study was conducted under three different environmental sites within the region introduced for the first time in Iraq through the import of new ZT seeder. The study implemented in 2006-2007 season compared with conventional agriculture and sowing after chisel plow. It was applied on numerous varieties belonging to the three field crops Bread Wheat , Durum Wheat and Barley.
The grain yield results showed that the ZT planting method was equal with farmer planting method (conventional tillage) in all locations and crops studied while chisel planting method was the superior in this trait , this result is encouraging for the adoption of this new technology because the input in a ZT doesn't need cultivation, while in other studied traits results showed that the chisel method excelled in 15 traits, while the ZT method excelled in 9 traits and the farmer methods in 4 traits only, this results strengthens the recommendation to adopt the ZT planting method for its limited implementation cost compared with the rest of the planting methods . In the same time grain yield in ZT planting method was not less than conventional tillage (con.) in any way.
