Abstract
In modern conditions the most effective way to increase the gross production of sunflower oilseeds is the selection of the most productive hybrids and realisation of their potential productivity by improving sunflower cultivation technology for specific soil and climatic conditions of the zone. Therefore, this topic is certainly relevant. Field experience was conducted on the experimental field of LLC ‘Kolos’ Mikhailovsky district of Volgograd region in 2020-2023. The main purpose of the research was to determine the optimal methods of basic cultivation, as well as a comprehensive assessment of the productivity of sunflower hybrids for the subzone of dark chestnut soils of the Volgograd region. On average for 2021-2023 years, the lowest photosynthetic potential of sunflower Suzuka was formed on the variant of disc tillage at a depth of 0.18-0.20 m without the use of leaf fertilisers with microfertilisers and was equal to 1062 thousand m2 day/ha. The lowest photosynthetic potential of sunflower Suzuka was formed on the variant of disc tillage at a depth of 0.18-0.20 m without the application of leaf fertilisers with microfertilisers and was equal to 1062 thousand m2 day/ha. The highest photosynthetic potential of 1755 thousand m2 day/ha was formed on the variant of ploughing to a depth of 0.25-0.27 m with the application of fertiliser Fulvigrain. The lowest biological yield on average for 2021-2023 years was formed on the variant of shallow disc cultivation without application of leaf fertiliser and was 2.04 t/ha. The highest biological yield was formed on the variant of ploughing to a depth of 0.25-0.27 m with the application of fertiliser Fulvigrain and was 3.02 t/ha.The lowest economic yield on average for 2021-2023 years was formed on the variant of shallow disc cultivation without application of leaf fertiliser and was 1.94 t/ha.On the variant with application of fertiliser Aidamin economic yield was 0.13 t/ha higher.In the variant with application of Fulvigrain fertiliser the economic yield was 0.21 t/ha more compared to the control variant.On variants of flat-cutting tillage at a depth of 0.25-0.27 m economic yield in comparison with variants on the background of disc tillage at a depth of 0.18-0.20 m was 0.48-0.63 t/ha more.The highest economic yield was formed on the variant of ploughing to a depth of 0.25-0.27 m with the application of Fulvigrain fertiliser and was 2.88 t/ha.
