Interaction of natural factors and crop cultivation technologies in their effect on the productivity of wheat and corn

The positive relationship between crop cultivation technologies and their productivity is shown. The advantages of the chernozem subtype with a heavy granulometric composition and the water regime of this soil were revealed in wheat and corn crops, the yield in this case increased 1.6–4.0 times compared with the productivity of crops on medium loamy soil. The effect of the combined application of nitrogen and phosphorus fertilizers to soils with a low content of mobile P2O5 (20–40 mg/kg) was clearly manifested. The elimination of weeds with herbicides was significantly more effective in fertilized wheat and corn crops. The interaction of fertilizer and herbicide made it possible to significantly increase the yield of these crops. On fertilized backgrounds in spring wheat crops, the herbicide Puma super combi was more effective, and the soil herbicide Acetal Pro was used in corn.
