Porumbeni 375 maize is an early-maturing simple interline hybrid with a FAO range from 300 to 380, providing a vegetation period of 90 to 118 days depending on growing conditions. This hybrid was developed at the "Porumbeni" Plant Institute in Moldova and adapted for cultivation in various regions of Ukraine, as well as in EU countries, Belarus, and Moldova. The plant is tall, reaching heights of 220 to 265 cm, with 16-18 leaves. The ear is weakly conical, 21-23 cm long, with 14-18 rows of dent yellow kernels, and 1000-kernel weight varies from 250 to 320 grams. The ear stalk is red, which is a characteristic feature of the hybrid.
Porumbeni 375 is distinguished by high yield and stable productivity under various growing conditions. Grain yield in steppe zones reaches 12-17 t/ha, and with adequate moisture and irrigation, yields can increase to 15-17 t/ha. The hybrid is recommended for grain, silage, and grain-stalk mixture production, and is characterized by a high ear proportion in silage mass. Grain extraction from the ear is 89-91%, and the grain loses moisture moderately quickly during ripening, which is important for timely harvest.
The hybrid exhibits high resistance to major diseases and pests, including stalk rot, stem rot, and lodging, and demonstrates good heat and drought tolerance. The plants have strong stems, ensuring resistance to lodging. Optimal plant density depends on conditions: in dry regions 55-60 thousand/ha, with adequate moisture 60-75 thousand/ha, and under irrigation up to 85-95 thousand/ha. For maximum yield, mineral fertilizers are recommended. Initial plant development is rated as good, promoting successful rooting and growth.
