11 IS 34 R

Sunflower variety 11 IS 34 R is a high-yielding crop intended for obtaining high-quality seed material with high oil content. The seeds of this sunflower have an oil content of about 42%, ensuring high oil yield during processing. Seed yield reaches 3.4-3.7 tons per hectare at optimal plant density up to 30,000 plants per hectare. The thousand-seed weight may reach up to 150 grams, indicating the variety's large-seed nature and its potential for industrial cultivation.

The sunflower development proceeds through several key phases, starting with germination, which lasts approximately 12 days after sowing. During this period, soil temperature is a crucial factor, as enzyme activity in seeds decreases below +5°C, slowing down the growth of the embryo. For successful germination, seed pre-sowing treatment and optimal agronomic conditions are recommended.

To enhance plant resistance and productivity, the application of growth stimulators such as Regoplant is recommended, applied foliarly at a rate of 50 ml per hectare 7-10 days after herbicide application. This treatment helps relieve plant stress, increases pollen production, and realizes the sunflower's genetic potential up to 99%. As a result, the quality and quantity of the harvest increase by 20-35%, making this variety attractive for farmers aiming for maximum production efficiency.
