Abstract: One of the factors affecting yield crops is application of suitable tillage and planting methods. Considering that Iran is a semiarid area and the water crisis is one of the limiting factors in agriculture. The study was conducted to evaluate the effect of tillage and planting methods on WUE and yield in wheat in 2008 in Ramin Agricultural University Research Farm. This study was performed as split plot in the form of completely randomized block design in three replication. Tillage treatments include reduced tillage (chisel once pensive) reduced tillage (twice chisel pensive) no-tillage and conventional tillage (moldboard plow and twice disk two times) in the main plots and planting treatments included 60 and 75 cm on beds and flat planting. The effect of tillage and planting method, on water use efficiency was significant wit tillage, 19.5 L m-2 on reduced tillage water consumption was shown. In planting methods, bed planting 60 cm with 25.9 L m-2 was the lowest water consumption. WUE of no tillage with 1.67 kg m-3 showed the highest value. In wheat yield among tillage treatments and planting no significant difference was observed. While grain yield in conventional tillage with the amount of 5657 kg ha-1 was the highest rate among tillage methods. Also, in methods of planting, flat planting with 6510 kg ha-1 was the highest grain yield.
