In particular, Mr. Yuriy Nagorny, an agronomist at the Ukrainian Scientific Institute of Plant Breeding (VNIS), underscores the importance of selecting sunflower hybrids that align with the specific cultivation technology suited to individual farms and regions. The choice of hybrid plays a pivotal role in determining agricultural success.
For instance, intensive hybrids require a good agricultural background and sufficient moisture. Without these conditions, farmers may face substantial additional costs associated with fertilizers. While intensive hybrids tend to be more demanding, their high yields can justify the investments. Farmers in regions with sufficient moisture and a lower risk of crop loss increasingly favor these hybrids.
On the other hand, farmers commonly utilize extensive hybrids in the arid southern regions of Ukraine. These hybrids are drought-resistant, require less fertilizer, and generally result in lower operational costs. Although extensive hybrids yield less than their intensive counterparts, they offer more stable and predictable yields year after year.
When choosing the appropriate sunflower hybrids, Mr. Nagorny advises considering several factors, including the cultivation location, soil characteristics, the farm's field history, and the region's climatic conditions. Key considerations also include:
- field condition;
- prevalence of diseases and pests in the region;
- types of common weeds;
- number of sunny days per year;
- average long-term rainfall during the growing season.
Notably, the Ukrainian company VNIS offers intensive and extensive hybrids, enabling farmers to select the most appropriate option for their needs and circumstances. This year, VNIS enhanced its portfolio by introducing four new hybrids: Almera, Mastak, Vegas, and Magnum.
