ES ABAKUS

ES ABAKUS — medium-early three-line hybrid corn (Zea mays L.), registered in the State Register for cultivation in the Volga and Lower Volga regions for grain production. The plant is tall with medium-width leaves, the leaf tip is acute or rounded, and the leaf is slightly curved with a medium-sized angle between the leaf blade and stem. A distinctive feature of the hybrid is the weak or absent anthocyanic pigmentation of the first leaf sheath and stem roots, while the anthocyanic pigmentation of the ear husk is strong. The ear is medium-length and thickness, slightly conical, with medium-intensity anthocyanic pigmentation of the central stalk. The grain is intermediate type with an orange upper part and yellow-orange lower part. The vegetation period ranges from 101 to 117 days depending on the region. The hybrid demonstrates high yield: in the Volga region, the average grain yield reaches 79.1 c/ha, 9.7% higher than the standard, and in the Lower Volga region — 53.0 c/ha, 17.7% higher than the standard. Maximum yield records were set in 2015 at 176.2 c/ha and 117.2 c/ha respectively. Grain moisture before harvest is at standard or lower levels, facilitating storage and processing. The hybrid is resistant to stalk rot and has moderate resistance to ear fusarium, as well as high resistance to lodging, powdery mildew, helminthosporium, and fusarium, ensuring stable yields under various weather conditions. To protect ES ABAKUS corn from diseases, the fungicide Abacus is recommended, which is an emulsion-suspension containing epoxiconazole and pyraclostrobin as active ingredients. This product provides long-lasting preventive and curative protection against a wide range of diseases, including septoria, brown leaf rust, powdery mildew, fusarium, and helminthosporium. Application of the fungicide increases yield, improves grain quality parameters, increases thousand-grain weight, stimulates photosynthesis, and extends the vegetation period. It is recommended to apply during the vegetative period at a rate of 1.5–1.75 l/ha for corn, enhancing plant resistance to stressful weather conditions.
