Pioneer PR62a91 Sunflower is a fast-maturing, high-yielding hybrid designed for cultivation in the most northern regions. Maturation period ranges from 110 to 116 days, and in the Polissia zone, the vegetation period can extend to 120-125 days. Early flowering and maturation allow for a stable yield under various climatic conditions. Plants are low-growing, reaching heights of 100 to 115 cm, which simplifies care and reduces lodging risk.
The hybrid exhibits high resistance to lodging and minimal residue, which improves subsequent crops. A distinctive feature is its large, unusually convex head. Early growth rate during initial development stages ensures good rooting and adaptation to growing conditions. Additionally, the hybrid is tolerant to downy mildew (races A-E), enhancing its disease resistance.
The main advantage of this variety is its high oil content, which has increased from 40% to 50-52%, with a yield potential of 52 centners per hectare. For maximum productivity, it is recommended to increase planting density and reduce row spacing. Low vegetative mass reduces residue, facilitating harvest and soil preparation for the next cycle.
