The article presents data on the study of sunflower in two crop rotations located on the slope of the Bolshoi Log beam, Aksay District of Rostov Oblast in 2015 - 2019. Studies have shown that to prevent possible water erosion it is recommended to use chisel processing as the main tillage. This will reduce soil washout by 14–26% and runoff by 16–32%. It was revealed that replacing naked fallow in crop rotation with perennial grasses reduced the amount of washed-out soil by 28% and reduced water flow by 25%. It is shown that all farming methods on sunflower must be performed in the direction across the slope, along the lines close to the horizontals. In the case of a surface runoff caused by melt or storm water, It is recommended to create the irrigation and drainage structures of the shafts - ditches across the slope. The economic assessment of sunflower growing in the system of contour-strip organization of the territory is given.
