Diego corn is a simple hybrid with a FAO index of 240, intended for grain use. This hybrid is characterized by high plasticity and adaptability, enabling successful cultivation in various soil-climatic conditions, including light soils. Plant height reaches 230-240 cm, and the vegetative period varies from 105 to 115 days depending on growing conditions. The ear is cylindrical, approximately 28 cm long, with 12-16 rows of yellow, vibrant kernels, ensuring high-quality yield. Diego has a high yield potential up to 13 tons per hectare (130 c/ha) and demonstrates stable performance even under adverse conditions. The hybrid is highly drought-resistant, resistant to diseases such as fusarium and smut, and resistant to late spring frosts in early growth stages. A strong stalk and branched root system provide reliable support to plants, preventing lodging and promoting rapid development in the early vegetative period. One of the key advantages of Diego corn is rapid moisture release during ripening, significantly reducing the need for additional drying of grain and lowering harvesting costs. The recommended planting density is 65,000–75,000 plants per hectare, which is optimal for achieving maximum productivity. The hybrid was developed by the Serbian Institute of Field and Vegetable Crop Research and is suitable for cultivation in various regions, including the Polissia, Forest-Steppe, and Steppe of Ukraine.
