| Popis: | In the arid conditions of the Nizhneje Pvovolzhje region, the farmers’ main task is to accumulate the greatest amount of moisture by the sowing crops time. This is largely facilitated by the correct choice of the basic tillage method. The results of the research carried out on Southern chestnut soils 2017-2019 were aimed at solving a complex of problems related to the development of the technology adapted to the conditions of the Volgograd region. The soil density observations in sunflower crops showed that the soil density during dump plowing by the plow PN-4-35 to the depth of 0.27-0.30 m for sunflower harvesting was 1.24 t/m3. With loosening by chisel “Rancho” to the depth of 0.35-0.37 m it was equal to 1.21 t/m3. When loosening by chisel “Rancho” to the depth of 0.35-0.37 m with a reservoir turnover of 0.15-0.17 m3 the density was 1.16 t/m3. When loosening by the chisel “Rancho” to the depth of 0.35-0.37 m with a pruning flat-cutting foot at the depth of 0.15-0.17 m it was 1.18 t/m3. The highest yield of sunflower was formed on the variant of chisel loosening by “Rancho” to the depth of 0.35-0.37 m with a reservoir turnover of 0.15-0.17 m. |
