【 摘 要 】

The paper presents the results of research and production experiments of spring wheat yield mapping. Five clusters were identified in terms of yield with an interval of 0.2 t/ha. With an average yield of spring wheat of 2.23 t/ha over an area of 13.7 hectares, it ranged from 1.91 t/ha to 2.71 t/ha. The reason for the heterogeneity of the spring wheat yield on this fragment of the field is a variety of soil cover. Detailing of soil fertility factors showed that in the low productivity area there was the lowest humus content (3.4%) in the 0-30 cm layer, nitrate nitrogen 5.1 mg/kg soil, mobile phosphorus - 46 mg/kg, exchangeable potassium - 55 mg/kg and pH - 4.2. The obtained data of yield mapping and detailed analysis of soil fertility factors in problem areas served as the basis for a technical solution with software for the differential application of mineral fertilizers in elementary areas in off-line mode.
