Wheat (Triticum aestivum) is important crop to feed human and livestock. Wheat as the main source of calories needed by the people and has the highest area under cultivation in the country. Various conventional tillage methods are used for preparing the seedbed and planting wheat. Due to rising costs of fossil fuels, increase in soil erosion, and shortage in water resources, new technologies in agriculture are needed to achieve higher yield. In recent years, conservation tillage systems that include a wide range of minimum tillage (shallower and with less frequency) and no-till systems have become more common in some part of the country. These systems typically save more moisture in the soil and consequently reduce water consumption. In this study, the effect of three different tillage-planting methods (including minimum tillage with a combined tillage machine )chisel-disk-roll packer) at 15 cm depth and planting with a combination drill, conventional tillage with a moldboard plow (alone) at the depth of 25 cm and planting with a combination drill, and a direct-drill method by using a direct seeding machine at the depth of 8 cm) on fuel consumption, water use efficiency, effective capacity of farm machines, tillage and planting costs, yield and yield components of irrigated wheat in two rotation, beans - wheat and potato - wheat were studied in a field located at Eqlid, Fars province. The research was conducted in a randomized complete block design with three treatments and six replications. The results showed that the fuel consumption in the direct-drill method and minimum tillage+planting by combination drill compared to moldboard plowing+combination drill planting reduced by 69% and 23%, on contrary, the field capacity was increased 29.9% and 34.7%, respectively. The results of combined analysis of variance showed that tillage+planting methods had significant effects on yield and yield components except 1000-kernel weight, But had no significant effects on water use efficiency. the first order interaction of rotation and tillage method had significant effect on water use efficiency. The maximum water use efficiency by as much as 1.59 kg/m3 was related to Direct seeding method in Beans - Wheat rotation and minmum water use efficiency by as much as 1.33 kg/m3 was related to Direct seeding method in Potato - Wheat rotation. The maximum (5305 kg/ha) and the minimum (5202 kg/ha) yield was related to mimimum tillage+planting by combination drill and conventional tillage + planting by a combination drill, respectively. Direct seeding method had higher yield than conventional tillage+planting with combination drilland had no significant difference with minimum tillage+planting by combination drill.
