This study was a randomized complete block experimental design with four treatments and four replications to determine the suitable furrows width for in-furrow grain drill and also wheat yield. Treatments were planting wheat by in-furrow grain drill with furrows width of 60, 75 and 100 cm and planting wheat on raised bed by conventional grain drill with furrow width of 60 cm (control). In this project, the effect of in-furrow grain drill on EC, seeds germination percent, 1000 seeds weight and crop yield were studied. Results indicated that in-furrow grain drill affected distribution of salinity (EC) in soil profile, seeds germination percent and wheat yield. The salt concentration at the top-center of beds and at the sides of the beds increased by 50.7% and 17.1% compare to mid-furrow, respectively. In-furrow grain drill with furrow width of 75 cm increased seeds germination (43.1%), 1000 seeds weight (5.9%) and crop yield (39.3%) compare to planting wheat on raised bed.
