Research of Some Maize Hybrids ( Zea mays ) in Kosovo’s Agroecological Conditions

Abstract

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 (%). 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.
