Grain drill performance can be affected by creating clods during seedbed preparation in dry soil conditions. To increase performance of grain drill in dry soil conditions need to design the new opener for grain drills. This study has been carried out for the economic evaluation of the suitable tillage method for planting by grain drill equipped with a bent leg furrow opener and their effect on the yield of irrigated wheat. This study was a randomized complete block experimental design with four treatments and four replications. Treatments were seeding winter wheat by a grain drill with bent leg furrow opener in three tillage practices of no-tillage (T1), reduced tillage (T2), and conventional tillage (T3). Seeding wheat by conventional grain drill in the conventionally tilled plots was also used as control treatment (T4). In order to investigate the economic effects of tillage and planting methods by the bent leg grain drill on wheat yield, the income and cost of treatments were measured, and using the marginal net profit analysis method, the economic rate of return on investment of each method. The results of showed that the most suitable treatment from the economic point of view is the bent leg tillage treatment + planting with a grain drill equipped with a bent leg furrow opener. The findings showed that the bent leg tillage + the bent leg grain drill, as a new technology, has the potential to increase crop yield and can increase the farmer's net profit.
