Methods of treatment of sunflower sowing

The article presents the research data on the study of the influence of different methods of treatment of sunflower crops in the dry steppe zone of the West Kazakhstan region. The aim and objectives of the research are to study the elements of adaptive sunflower cultivation technology in order to provide producers of vegetable oil with high-quality raw materials. To obtain high sunflower yield it is very important to choose the correct seedbed preparation. As a result of the research, the productivity of sunflower was established depending on the methods of crop treatment. In our studies, the greatest weediness of sunflower crops was in variants without the use of herbicides. The lowest number of weeds (19 pcs./m², with the wet weight of 36 g/m²) was recorded in the variant with the administration of the herbicide Roundup with the combination of harrowing and pre-sowing cultivation. The different methods of treatment also had an effect on the size of the above-ground biomass. The highest biomass was observed in the variant with herbicidal technology (6.05 t/ha), the lowest one - in the control (4.65 t/ha). The highest yield of sunflower seeds (2.35 t/ha) was recorded after the administration of Roundup and harrowing with pre-sowing cultivation. In the control variant this indicator was 1.79 t/ha. The yield in the variant with harrowing, pre-sowing cultivation and one inter-row cultivation was 1.85 t/ha; it increased by 0.06 t/ha in comparison with the control variant. As shown by the research data, the yield of sunflower in the dry steppe zone depended on adaptive technology. At the same time, the highest productivity of sunflower was established during cultivation harrowing + presowing cultivation with the administration of Roundup (2 L/ha).
