PORUMBENY 223 ASV

PORUMBENY 223 ASV — this is a simple two-row medium-early hybrid maize (Zea mays L.) with a maturity period of 108-114 days and FAO 370. The plant is tall, reaching a height of 250-265 cm, has 17-18 medium-width, slightly curved leaves. The ear is large, with 16-18 rows of dent, yellow, elongated kernels. The 1000-kernel weight is approximately 300-350 g, and the grain yield upon shelling reaches 89-91%. The main ear axis is higher than lateral branches, with dense ears and weak anthocyanic coloring of silk and leaf sheaths. The hybrid exhibits high resistance to southern helminthosporiosis, bacterial disease, and stalk rot, as well as moderate resistance to common smut. However, it is susceptible to corn stem borer. PORUMBENY 223 ASV has high heat and drought tolerance, resistance to ear and stalk rot, ensuring stable productivity under various growing conditions. The plant demonstrates good growth and development, and the grain moderately loses moisture upon maturity. The hybrid is recommended for grain, silage, and grain-silage mixture production. Grain yield varies depending on growing conditions: in steppe zones it reaches 92-97 c/ha, on more humid territories — 152-176 c/ha. The optimal plant population is 55-60 thousand/ha in dry regions, 65-75 thousand/ha with adequate moisture, and 85-95 thousand/ha on irrigated lands. The high ear content in silage mass makes this hybrid a versatile and productive choice for various agroclimatic conditions.
