The sunflower hybrid NS H 6320 is a high-yielding variety intended for cultivation in various climatic zones, including steppes and forest-steppe. Plants reach a height of 140 to 160 cm, ensuring good stability and optimal development. The vegetation period is 108 to 112 days, allowing the hybrid to successfully adapt to the conditions of the central region and southern areas.
NS H 6320 is characterized by high seed yield, which can exceed 45 centners per hectare, reaching more than 50 centners per hectare under favorable conditions. The mass of 1000 seeds varies within 105-120 g, indicating large-fruitedness and high quality of seed material. Oil content in seeds is 47 to 50%, making this hybrid attractive for the oilseed industry and confectionery production.
The hybrid possesses resistance to main sunflower diseases, such as root-knot nematode, Phoma, Phomopsis, white and black stem rot, and downy mildew. This ensures crop stability and reduces the need for intensive chemical protection. The recommended sowing density is 50-58 thousand plants per hectare depending on the region, which contributes to optimal use of area and maximum return from crops.
