The TOPAZ grain sorghum variety is an early or early-maturing variety intended for producing food-grade grains and grain fodder. It is characterized by high grain yield, reaching 4.3-4.5 tons per hectare, as well as significant green mass output—ranging from 21.3 to 25.2 tons per hectare. Plants reach a height of 135-145 cm, ensuring good biomass for feed purposes. The weight of 1000 grains is approximately 28.5 grams, while protein content in the grains varies from 12 to 13%, with starch making up 73-76%, making the grain nutritious and valuable for both food and feed use.
TOPAZ exhibits resistance to lodging and drought resistance at the level of standard varieties, allowing it to be grown in various climatic conditions, including the Lower Volga and Ural regions. The maximum registered yield was 34.8 centners per hectare, confirming its high productivity and adaptability. The recommended planting method is wide-row with a row spacing of 70 cm, which promotes optimal plant development and facilitates agricultural operations.
The TOPAZ variety is widely used for both feed and food purposes, thanks to its high technological and biological characteristics. It is suitable for producing food-grade grains and for use as grain fodder, providing quality nutrition for animals. Resistance to adverse conditions and high yield make this variety an attractive choice for agricultural producers seeking stable and efficient sorghum cultivation.
