In the experiment, we have studied the effect of the use of an intelligent spreader on increasing the efficiency of nitrogen fertilizers used to feed winter wheat in ordinary chernozem. The studies were carried out in the production conditions of land use by AO SHP Kolos in the Kochubeyevsky district. In this article, we have examined the effect of a sprayer (Amazone UG 3000 Nova) and an intelligent mineral fertilizer spreader (Amazon ZA - TS - 4200) using touch sensors to determine the NDVI development index on the efficiency of nitrogen fertilizing winter wheat. Based on the experiments, it was found that, on average, over the two years of the study, the largest increase in the yield of winter wheat grains was noted in the variant with the introduction of ammonia nitrate in the first and second fertilizers using the intelligent fertilizer spreader Amazon ZA - TS - 4200 according to the NDVI - 6.53 t / ha. The highest structural indices of winter wheat grain yield were also noted in the variant with the introduction of ammonium nitrate in the first and second fertilizers using the Amazon ZA - TS - 4200 intelligent fertilizer spreader according to the NDVI index. So, the height of plants increased by 16.3 cm, the number of productive stems per 1 m2 by 37 pcs. The number of grains in the ear - by 5 pcs., The weight of 1000 grains - 0.8 g. According to the results of the experiments, it was established that in the conditions of land use by JSC "Agricultural Enterprise" Kolos "of the Kochubeyevsky District of the Stavropol region when planning the harvest of winter wheat - 6.5 tons / ha, it is advisable to use in the first and second top dressing of ammonium nitrate with a dose of 150 kg / ha, using the Amazon ZA - TS - 4200 intelligent fertilizer spreader according to the NDVI index
