Sunflowers are giants in the world of flora
Sunflowers are more than just a symbol of summer. As robust and versatile crops, they play an important role in agriculture. Particularly in times of climate change and increasing demand for organic cultivation methods, it is essential to find innovative and environmentally friendly solutions for plant protection and crop care. This is where our product HS®-300BIO BASIC comes into play. In a recent series of tests, we were able to analyze the effectiveness of HS®-300BIO BASIC in sunflower cultivation. The results are of interest not only to farmers and landscapers, but also to anyone interested in sustainable agriculture and organic crop protection.
Sunflower as a crop for edible oil production
Sunflowers occupy a special place in agriculture. They are highly adaptable, require relatively little care and are an important source of oil and protein. At the same time, they have a supporting effect on the soil structure, as they reduce soil compaction and reach deeper layers of nutrients. HS®-300BIO BASIC from Humintech was developed to further support plants in these areas.
Sunflower as a test crop: an important role in agriculture
How HS®-300BIO BASIC was tested:
The test was carried out in 2023-2024 in the test field of Humintech GmbH, Am Pösenberg 9-13, 41517 Grevenbroich, Germany. The test variety is the RGT hybrid BILLYKID, a mid-season variety with a high oil content of 46-47% and oleic acid of 88-89%. The recommended sowing density is 70-75,000 plants per hectare. The plants were sown on loamy soils with a pH value of -7.0. The soil analyses are given in Table 1 below. In addition, 500 kg/ha Kalksalpeter-27, 25 kg/ha Ferty 1 and 10 l/ha HS®-300BIO BASIC dissolved in 300 liters of water were added to the soil before sowing.
Test results:
HS®-300BIO BASIC has a good effect on the growth and development of sunflower. During the growing season, uniform plant development, strong plant development, uniform flowering and ripening were observed compared to the control. HS®-300BIO BASIC increases the quantity and quality of the harvest.
The results show an increase in seed yield by more than 15% in 2023 and more than 14% in 2024. It is known that humic substances not only increase the yield of sunflower seeds, but also the oil content in the harvested seeds. Our results show that the control plants have an oil content of 41.7% (2023) and 42.4% (2024), while the plants treated with HS®-300BIO BASIC have an oil content of 43.5% (2023) and 44.4% (2024): an increase in oil yield of 20.3% (2023) and 19.6% (2024)!
To summarize, the application of 10 l/ha of HS®-300BIO BASIC has a very positive effect on plant growth and development, which is reflected not only in higher yields, but also in the yield characteristics, in our case in oil content: an investment that pays off!
