Experiments were laid out to investigate the germination ability of immature sunflower seeds. Seeds of different age after fertilization were planted directly into bags filled with soil mixture. The experiments, conducted in the period 1984-1986, proved the possibility of sunflower cultivation with immature seeds directly in soil, without artificial nutritive media. Seeds are removed from a head 10 or 12 days after fertilization and immediately planted (do not permit them to dry) into bags with soil mixture. Our method is simple and easy. It does not demand special equipment, tools and specially prepared nutritive media and allows getting six vegetative cycles per year. It permits to obtain different line analogues in a single year instead of 6 or 7 years.
