White cabbage Diadom F1 is a medium-early subtropical hybrid intended for cultivation in open ground during the summer. The maturation period is approximately 68-72 days after transplanting seedlings. Heads are round, dense, weighing 2 to 2.5 kg, with a tender dark green color and excellent internal structure. Leaves are thin, and the stem is short, ensuring high quality and attractive appearance. The hybrid is characterized by high yield, good root storage, and resistance to fusarium, making it a reliable choice for various cultivation zones, including subtropical regions.
Diadom F1 is suitable for dense planting at a density of 45-55 thousand plants per hectare, promoting efficient land use and increased yield. The cabbage tolerates long-distance transportation, expanding its market potential. It is recommended for fresh consumption due to excellent protection of heads against sunburn and long-term preservation of marketable appearance.
Botanical and biological features of Diadom F1 cabbage include a well-developed root system penetrating the soil to a depth of 40-50 cm. The crop is cold-resistant: seeds germinate at 2-3˚C, optimal germination temperature is 18-20˚C, and hardened seedlings can withstand short-term frosts down to -5-6˚C. During the vegetative period, the optimal temperature is 15-18˚C, and growth continues during head formation at 5-10˚C. The cabbage has moderate light requirements but is very demanding in terms of moisture, with optimal soil moisture at 75-80% NH. Proper nutrient balance, especially nitrogen, phosphorus, and potassium, is crucial for successful cultivation; loamy soils with slightly acidic reaction (pH around 6) are considered best.
