Sunflower is a strategically important oil crop, the history of which has evolved from a wild plant to the cornerstone of agribusiness. To achieve high productivity, an agronomist must consider the biological characteristics of the plant, correctly establish a weed control system, including dangerous quarantine species, and apply modern harvesting preparation techniques. Competent management of the technological process allows for minimizing risks and increasing the economic efficiency of cultivation.
This selection contains expert materials covering the key stages of the crop's life cycle. Readers will find practical recommendations on the application of post-emergence herbicides and the protection of mixed sunflower and maize crops. The articles also describe in detail modern methods of desiccation to accelerate ripening, mechanisms for regulating plant growth using phytohormones, and principles for evaluating the economic efficiency of mineral nutrition. This information will help specialists systematize approaches to monitoring the phytosanitary situation and optimizing agrotechnical operations to obtain a stable harvest.
