Radish variety 'Sturdy Nut' is an early-ripening variety intended for cultivation in open and protected ground. It is characterized by synchronized production release and forms a high-quality crop as early as 3-3.5 weeks after germination. The root crops have a round or slightly oval shape, bright coloring, and a mass of 20 to 35 grams. The flesh is white, dense, semi-glassy, with a tender and juicy structure, possessing a mildly sharp, refreshing taste, making this radish an excellent choice for vitamin salads. The 'Sturdy Nut' variety is resistant to flowering and adapts well to low-light conditions, allowing for successful cultivation in various climatic conditions. Yield under film covers reaches up to 4.0 kg per square meter, indicating the high productivity of the variety. To obtain a continuous harvest, seeds are recommended to be sown several times during the season with an interval of 15-20 days. Sowing is done to a depth of about 2 cm, and at the stage of the first true leaf, seedlings are thinned for optimal plant development. 'Sturdy Nut' radish can be used as a companion crop on cabbage, cucumber, and tomato plantings, and can also be grown as a follow-up crop after harvesting early vegetables. Successful cultivation requires timely watering, weeding, and soil loosening, which contributes to the formation of a high-quality and tasty crop.
