Maize SY CHORINTOS

SY Chorintos — a mid-early simple hybrid corn from Syngenta, intended for grain and silage production. This hybrid is characterized by high adaptability and the ability to ensure stable and high yields under various soil-climatic conditions in Ukraine, including the Polissia, Forest-Steppe, and Steppe zones. Grain type — dent, with starch content ranging from 72–75% and protein 8.8–9.2%. Average grain yield at harvest is 79.2–81.9%, with a potential yield of 14–15 tons per hectare. Maturity group — mid-early, FAO ranging from 290 to 310, ensuring rapid grain moisture loss during maturation and enabling harvest without additional costs.

The SY Chorintos hybrid features strong early growth and the Stay Green plant type, promoting longer vegetative periods and improved silage quality. It exhibits high resistance to major diseases, including common rust, root and stalk rot, helminthosporiosis, and ear fusarium. Moreover, the hybrid demonstrates excellent drought and cold tolerance, making it a reliable choice for cultivation under stress conditions. The seed material is suitable for replanting on the same field, including monoculture, which enhances economic efficiency.

Recommended cultivation practices include early planting at soil temperatures of +6...+8 °C at seed depth. Recommended planting density depends on moisture conditions: under adequate moisture — 80–85 thousand plants per hectare for grain and 88–93 thousand for silage; under insufficient moisture — 55–60 thousand and 60–66 thousand plants, respectively. Seed treatments with Force Zea and Viberans are recommended to prevent damage from soil pests and stimulate root development, providing additional protection against secondary infections and stress.
