Aim. The aim of the research was to identify the effect of types of fertilizer on increasing soil fertility and corn yield of grain and sorghum in conditions of irrigation of the Tersko-Sulak subprovince. Methods. Carrying out some field experiments: conducting observations and laboratory tests, selection of soil and plant samples was carried out according to generally accepted methods: statistical processing of yield data was carried out by the method of variance analysis based on Kirov Federal State Unitary Enterprise and FSBSI Dagestan Agricultural Research Institute named after F.G. Kisriev. Results. Studies showed that in the post-harvest period after harvesting winter wheat, it is better to cultivate green manure with the presence of legumes. A valuable biological feature of them is the ability to absorb atmospheric nitrogen. The powerful root system of the seeding pea improves the physical properties of the soil, as well as microbiological activity. The most favorable conditions are created for the growth and development of maize and sorghum, after plowing of fertilizers in the stubble period in the conditions of irrigation of the Tersko-Sulak subprovince, by applying mineral fertilizers at a dose of N150 P75 K75, seeding peas, manure (30 t / ha), In these cases, on average, over two years, the highest yield of maize was 5.6-5.7-5.5 t / ha and grain sorghum, respectively, 4.7-4.8-4.5 t / ha. Conclusion. For the first time, in conditions of irrigation of the Tersko-Sulak subprovince, were obtained the results on the effectiveness of different types of fertilizers introduced into the soil.
