Seiddi corn is a high-yielding, mid-ripening hybrid with FAO 310, characterized by a tri-line type and silvery-ribbed kernel. The plant reaches stalk heights of up to 280 cm, with ear attachment height of about 120 cm. The hybrid exhibits high initial growth energy, 14 rows per ear, and 33 kernels per row. The 1000-kernel weight is 248 grams, and the potential yield reaches 116.2 centners per hectare, making Seiddi attractive for cultivation under various climatic conditions. Seiddi shows good resistance to diseases and adverse factors. Resistance ratings for early lodging, lodging at harvest, regenerative capacity, and phytosanitary condition are at 6-7 points, while resistance to helminthosporium and blister rust reaches 7-8 points. Recommended planting density varies by conditions: in dry areas — 65-72.5 thousand seeds per hectare, in well-watered zones — 75-82.5 thousand seeds per hectare. For successful cultivation of Seiddi corn, it is essential to thoroughly prepare the soil starting in autumn, and apply soil herbicides in spring to control weeds at germination stage. Observing optimal planting dates when soil temperature reaches +10 degrees Celsius and using quality agrochemicals will help avoid yield losses due to pests and diseases. Herbicide, fungicide, and insecticide applications are recommended on dry, windless days using properly calibrated sprayers. For harvesting, use modern equipment minimizing losses, and consider an insurance premium of 5-20% over the planting rate to ensure high germination.
