In particular, Yuriy Nagorny, an agronomist at the Ukrainian Scientific Institute of Breeding (VNIS), recommends that when choosing hybrids, they should be carefully considered for their suitability for the cultivation technology that is appropriate for a particular farm and region, because it is the type of hybrid that will ultimately determine it.
For example, the intensive type requires a good agricultural background and sufficient moisture. Otherwise, serious financial costs are required for fertilizers and fertilizing. Intensive hybrids are more capricious, but all investments are compensated by higher yields. They are now more often relied on by producers in regions with sufficient moisture and a lower probability of crop losses.
In contrast, the extensive type is usually used most by farmers in the arid regions of southern Ukraine. These hybrids are drought-resistant, so they do not require much fertilizer and generally have lower costs. They produce lower yields than the first variant, but more stable and predictable yields from year to year.
When choosing sunflower hybrids, the expert advises to take into account both the place of cultivation, soil characteristics and history of the farm's fields, as well as the climatic features of the region. Also important are:
- field condition;
- prevalence of diseases and pests in the region;
- type of the most common weeds;
- number of sunny days per year;
- average long-term rainfall during the growing season.
It is worth noting that the Ukrainian company VNIS has both intensive and extensive hybrids, among which you can easily choose the one that will perform best on a particular farm. This year, the manufacturer also expanded its portfolio by introducing four new hybrids: “Almera, Mastak, Vegas and Magnum.
