Starting the growing season of sunflower with a balanced nutrition is a key factor ensuring high sunflower yields and oil content.
Sunflowers are very efficient in extracting nutrients from the soil and responds well to nitrogen fertilization. Nitrogen is important for photosynthesis, productive growth and yield. However, it is not advisable to fertilize with very high doses of nitrogen as this leads to a rapid growth of the plants, consequently increased disease susceptibility, and lower oil content.
Phosphorus plays an important role in the synthesis of fatty acids and oil, accelerating the growth of the root system of young plants.
Sunflower need large amounts of potassium. Potassium increases seed yields and increasing their oil content. Further it is important to improve,drought resistance and strength oft the plants, reducing the damage caused by fungal and bacterial diseases. Compared to nitrogen fertilization alone, the application of a balanced NPK fertilizers improves yields significantly.
