Relevance. One of the important elements of adaptive sunflower cultivation technology is the system of pre-sowing tillage, which is aimed at the maximum destruction of seedlings and seedlings of weeds, preserving the accumulated reserve of soil moisture and creating optimal conditions for seed germination. The aim of the research is to study the elements of adaptive technologies of sunflower cultivation (methods of crop care) to increase its productivity and provide vegetable oil producers with high-quality raw materials. Methods. According to the morphological features of the genetic horizons of the profile and agrochemical indicators of the arable soil layer of the experimental plots, they are characteristic of the 1st dry-steppe zone of Western Kazakhstan. The area of plots for sunflower cultivation is 90m2, the repetition is three times, the location of plots is randomized. The experiments used a hybrid of sunflower Avangard. Seeding rate recommended for the dry-steppe zone of the West Kazakhstan region. During the research, nitrogen and phosphorous mineral fertilizers were used in the recommended doses for the region. Results. As a result of research on methods of crop care in the conditions of the 1st dry-steppe zone of the West Kazakhstan region, it was found that to control weeds on sunflower crops, it is advisable to harrow the soil with pre-sowing cultivation and use the herbicide roundup 5 days before sowing with a rate of 2 l/ha (option 2), where high structural indicators were noted and the highest seed yield was obtained
