An open-air production experiment was staged at an agricultural enterprise in the Berezovski district. Here, 23 corn hybrids are grown in one field. Samples were brought from different countries, so one can compare the corn grown from Belarusian and imported seeds. According to agronomists, our samples look decent against the background of imported ones. In addition, domestic seeds are more efficient economically as sowing requires half as many material. Seeds for corn in Belarus are produced at two factories.
