In the Volgograd region, 3-year field experiments were carried out on chernozem soils of cultivating corn for grain using the resource-saving Strip-til technology. The two-factor experiments made it possible to establish the optimal precursor for corn for grain and fertilizer application rates. The crop predecessor was taken as factor A (A1 - winter wheat, A2 - corn for grain, A3 - sunflower), and the use of fertilizers was taken as factor B (B1 - N 50 P 16 K 16 , B2 - N 32 P 32 K 32 ). The maximum yield was noted for the predecessor winter wheat against the background of fertilizers N 50 P 16 K 16 - 6.12 t/ha, in the variants for all predecessors when applying fertilizers, more economical water consumption was established, moisture was spent most efficiently to create 1 ton of yield in the variant with the predecessor winter wheat against the background of fertilizers N 50 P 16 K 16 -443.51 m 3 /t. Ineffective moisture consumption was established for the predecessor sunflower on an unfertilized background - 973.67 m 3 /t.
