The study looked at different types of maize plants in Kosovo to see which ones grew best. They tested seven hybrids from two breeding institutions and found that one hybrid, H-6, performed the best in the conditions. In the second year, most traits like leaf area and growth rate were higher than in the first year. Overall, H-6 was the most suitable for growing in Kosovo, while H-4 and H-5 were not as good in those conditions.
