Abstract

In 2014–2015 year at ASU expermental station, experment has been done, in which we researched three diffrent winter wheat species. In expermental area soil was Calcareous Epihypoglyic (IDg8-k), in FAO classification Calc(ar)i- Epihypogleyic Luvisol (LVg-p-w-cc). Overall area space–40 m2, accaunting area – 20 m2 . Experment was carried in three replays and fields were randomly set out during replays. A factor – species: 'Olivin', 'Ada', 'Edvin'. B factor – diffrent nitrogen fertilize ration. During tillering period, the fields were fetillized two times with ammonium nitrate in 2015-03-16d. - N68 and 2015-04-22 d. - N55 (background fertilization). In period of elongation (2015-05-26d.) we did additional fertilizing on the leafs with urea solution N20. Without additional fertilizing, the biggest grain harvest ripen was with ˈEdvinˈ winter wheat species. With additional fertilizing in period of elongation with urea solution N20 on the leafs, the rate essentially increased winter wheat species 'Olivin' (0,74 t ha-1) and 'Edvin' (0,59 t ha-1) productivity, essentially increased all grain species protein rate and wet wheat gluten amount. The biggest protein amount (13,3 perc.) and wet wheat gluten amount (27,2 perc.), was established with 'Ada' species grain
