Megjegyzések:	The aim of this study was to analyse the problems caused by weather and its consequences and thealternatives of improving quality with fertilisation and irrigation. Examinations were performed in amoderately warm and dry production area in Eastern Hungary (47o 33' N, 21o 26' E, 111 m asl) on mid-heavycalcareous chernozem soil in 2011, 2012 and 2013. Six N doses were used in the field experiment(0,30,60,90,120,150 kg ha-1) in non-irrigated and irrigated treatments. The examined hybrids were FAO 390,FAO 410 and FAO 450.Averaged over the examined years, three-way ANOVA showed that fertilisation, hybrids and crop years had asignificant effect (P<0.001) on grain protein content and irrigation had no such effect. Based on MQ values,fertilisation had the most significant effect (21.865), followed by crop year (19.275) and hybrids (6.107).Protein content linearly increased with increasing fertiliser doses. Averaged over treatments, the fertiliser doseof 150 kg N ha-1 (8.3 g per 100g dry matter, P<0.001) provided better conditions for the development of extraproteins. Irrigation slightly reduced protein content, although this difference is not significant. The FAO 410hybrid had the highest protein content (7.6 g per 100g dry matter) both in non-irrigated and irrigatedtreatments. Of the examined years, the driest year of 2013 resulted in the highest protein content (7.6 g per100g dry matter) and the closest correlation (r=0.789***) between fertilisation and protein content.
