Barley (Hordeum vulgare L.) is one of the most important cop in the world. It is used as raw material for fodder, brewing, bakery and foodstuff industry. Barley needs nutrients and nitrogen is the most important. Barley takes nitrogen 100 to 120 kg per hectar as ammonium and nitrate, which it uses during the growing season to form biomass and leaf chlorophyll to photosynthesize. Nitrogen deficiency causes dwarfism to stem and undeveloped state to phosynthesizing leaves. Nitrogen can be applied as inorganic and organic fertilizers and also as microbe content organic mineral fertilizers. The aim of the thesis was to examine how conventionally and organically cultivated methods affected two-row barley’s yield and quality in field experiment in 2009. There were six different cultivation methods; Berner Plant protection, University of Helsinki, Nylands Svenska Lantbrukssällskap (NSL) and Raisio Agro used conventionally cultivated methods and Elosato and ProAgria Organic used organically cultivated methods. Treatmens were fertilized by nitrogen from 71 to 118 kg per hectar where conventionally cultivated treatments were fertilized by nitrogen from 85 to 118 kg per hectar and organically cultivated treatments were fertilized by 71 kg per hectar. Seed population was from 400 to 500 seeds per m2. The results indicated that NFC Tipple matured 4 to 5 days earlier in organically cultivated treatments than conventionally cultivated treatments which had an effect to grain size. Early maturing was caused by low nitrogen fertilizer amount and plant disease amount. Vigorously grown barley resulted in higher yield and better yield quality when it was conventionally cultivated in comparison to organically cultivated. Quench responded better to nitrogen fertilizer when nitrogen than NFC Tipple and Fairytale. Number and timing of fungicide treatment had no effect to Quench’s growth’s disease amount.
