Canadian hybrid sunflower TAXOFA — 69. Sunflower (Sunflower seeds). TAXO FA — 69 is a vigorous hybrid sunflower. Developed based on nanotechnology by the well-known Canadian Holding SERTIS and the American chemical concern UNION CARBIDE in 2011, it demonstrated excellent drought resistance due to Canada's harsh climate, and also passed hybrid trials in Canada, Russia, Rostov Oblast, Kursk Oblast, Bashkortostan, Saratov Oblast, Israel, Kazakhstan, Mexico, Tajikistan, India, average temperature + 50 C*. Plant height from 1.50 m — 1.60 meters, stem thick, straight, strong, high circumference of 10 cm, root strong, penetrating into the soil to a depth of up to 4 meters, leaves medium, flower heads diameter from 20 cm — 25 cm, seeds small. Characterized by good drought resistance up to +50 C*, uniform ripening, resistant to lodging and shattering (heavy rains, hurricane winds, hail). Sunflower is harvested directly and does not require desiccation. This hybrid is resistant to all sunflower diseases that affect common varieties and hybrids (e.g., rust, downy mildew, powdery mildew, false downy mildew, rust, phomopsis, white, gray, ash rot, septoria, ascochitosis, bacterial disease, angular brown spot, chlorosis, bacterial wilting, bacterial root rot, macrophomina, etc.). Resistant to all harmful insects (e.g., sawfly, meadow moth, May beetle, sand beetle, sunflower thistle, firefly, sawfly, southern gray longhorn, white moth, winter cotton bollworm, aphid, etc.). Resistant to abiotic stresses (sudden temperature fluctuations from +50 C* to -18 C* throughout the entire vegetation period). Oil content in the oilseed sunflower hybrid is 50% — 52%. This hybrid is self-pollinating and does not require the presence of bees. Resistant to acidic rains and high temperatures; pollen does not burn at high temperatures. This sunflower hybrid was sown in Ukraine in 2012 in Dnepropetrovsk Oblast, Kyiv Oblast, Autonomous Republic of Crimea, Kharkiv Oblast, and showed excellent yields of 42 — 45 centners per hectare. Canadian sunflower TAXO FA — 69 tolerates early spring frosts — 18 C. The mass of 1000 seeds of the Canadian oilseed hybrid TAXO FA — 69 sunflower is 60 — 65 grams. Germination rate — 97%, Energy of germination — 97%, Purity — 99.99%, Moisture — 8%, Purity — 99.99%. The yield of the Canadian oilseed sunflower hybrid TAXO FA — 69 is 42 — 48 centners per hectare. Sowing Sow the hybrid sunflower early in spring from March 1 to May 26, inclusive, at temperatures of +1 C, +2 C, as it is not afraid of spring frosts; sunflower seedlings emerge within 8 — 10 days. The seeding rate of the Canadian hybrid TAXO FA — 69 per 1 hectare is 7 kg, sown at a depth of 5 cm, using the dotted method with row spacing of 70 cm x 35 cm, using pneumatic seeders SUPN — 8, SKPP — 12, SPG — 6 MF. Sunflower yield depends on stand density; for southern steppe regions, optimal stand density is 50 — 55 thousand plants per hectare, for northern steppe regions 60 — 65 thousand, for forest-steppe regions 70 — 75 thousand per hectare. For sunflower, fall plowing is recommended. Pre-sowing soil preparation should ensure a loose, well-crumbled soil. Only well-dried soil should be worked. Surface application of fertilizers simultaneously protects the soil from waterlogging. Herbicides should be used as needed depending on the weed spectrum — Harnes at 1.5 — 3 liters per hectare before sowing, immediately after sowing until emergence, Select 1.4 — 1.8 liters per hectare regardless of plant stage, Centurion 0.6 — 0.8 liters regardless of plant stage, Plenj 80 grams per hectare at any stage of sunflower development. Fertilizers Application of phosphorus and nitrogen fertilizers not only increases yield but also oil content; recommended application rates are 80 — 85 kg of superphosphate at sowing time and 120 — 130 kg of nitroammophoska per hectare either before sowing or at emergence. Insecticides — not used, as this hybrid is resistant to all harmful insects; fungicides — not used at all. Vegetative period of the sunflower hybrid TAXO FA — 69 from sowing to harvest is 100 — 110 days (early). Harvesting should begin when 85 — 90% of sunflower heads have turned brown, and harvesting is performed using standard combines Don, John Deere, Case. Economic justification. Purchase price for 1 ton of oilseed sunflower is 4600 UAH; harvest from 1 hectare yields a minimum of 4.2 tons and a maximum of 4.8 tons, totaling 19,320 UAH. Costs per 1 hectare amount to 1,140 UAH, including herbicides, plowing, cultivation, diesel fuel, drying, and harvest operations. Fertilizers, insecticides, herbicides, growth regulators — used according to requirements and application technology.
