The object of the study is to investigate the suitability of some hybrids (Zea mays l) from Seed Origin: Croatia (Hybrids Institute of Zagreb BC), Standard (NS 640 and NS 640 Hybrids). There were investigated six maize hybrids: BC 288, BC 354, BC 394, BC 408, BC 418, BC 5982, while the comparative hybrids (Standard) are NS 444, Standard NS 640. The research was conducted in two agro-climatic regions of Kosovo (in Arbnesh, on the research farm of the Agriculture Institute of Kosovo, Peja – Dukagjini’s Plain, and in Pestovo – Kosovo’s Plain, the private property of the company called “Pestova”. There were investigated these parameters; the height of the stump placement on the stalk, the height of the plant, the number of trams per plant, the length of the tram, the weight of the tram, the weight of grains on the tram, grain weight, humidity, the weight of 1000 grains (Absolute P.), seed protein content (%), the content of seed fat (%). Maize (Zea mays) is a very important crop, which originates from America. In recent years, in Kosovo, there have been cultivated around 70,000 - 85.000 ha each year with little oscillations year after year. An interest and need of primary importance for Kosovar agriculture is the regionalization of hybrids, not only in terms of their products but also due to their dedication or use. The selection of hybrids with high genetic potential as well as high adaptability to our country’s agro-climatic conditions will also be a priority in the future. The agro-climatic and pedological data of Kosovo, compared to the yields obtained in maize culture indicate that the genetic potential of hybrids cultivated here is not exploited. The obtained results showed that there were statistically significant differences at different levels for traits investigated across the hybrids included in the plots relative to the standard (NS 444, NS 640.) and between localities.
