Maize DB Varta

DB Varta is a simple modified medium-early hybrid of sweet corn with FAO 280, intended for grain production. The hybrid was registered in the Variety Register since 2020 and was developed by the Institute of Grain Crops of NAAN of Ukraine. The plant reaches a height of 220 cm, does not bush, and the ear is attached at a height of 90-95 cm. The ear is cylindrical in shape, 22-23 cm long, with 16 rows of toothed kernels of yellow-orange color and a white cob. Grain yield is 81-82%, 1000 kernels weight — 280-300 g.

The hybrid is characterized by high drought and heat tolerance, as well as good cold resistance. It is resistant to stem lodging, major diseases and pests, which ensures stable yields. DB Varta withstands prolonged plant stand and exhibits intensive grain moisture release, which contributes to good maturation and harvest. The hybrid positively responds to improved growing conditions, allowing high yields under optimal agronomic practices.

The hybrid can be grown in the Steppe, Forest-Steppe, and Polissia regions. The recommended plant population varies by region: 55-60 thousand plants/ha in the Steppe, 80 thousand plants/ha in the Forest-Steppe, and 90 thousand plants/ha in Polissia. The average yield in ecological trials during 2017-2019 was 7.45 to 9.33 t/ha at grain moisture content of about 14-19%. Maximum yield under irrigation reached 14.02 t/ha, confirming the hybrid’s high productivity under favorable conditions.
