This work is aimed to determine and analyze the impact of nutrition and fertilization, genotypes and year-class to the height and technological quality of the yield of winter barley grown at the EXBA FAPZ SPU site in Nitra - Dolná Malanta. Field semioperational experiments with two monitored genotypes of winter barley (Wintmalt and Malwinta) were established in the 2008/2009 and 2009/2010 periods with four fertilization variants in three repetitions using the tillage method and maintaining randomness. We used two genotypes to monitor selected indicator technology - extraction. The average yield reached 7.83 t per ha for 2008/2009 for both monitored genotypes and 7.76 t per ha in 2009/2010. Wintmalt reached lower yield of 0.15 t per ha if compared to Malwinta - 7.87 t per ha for both monitored years. In 2008/2009, the d-fertilization variant (NH4N03+HAK0FYT extra) - 9.58 t per ha was the best fertilization variant for Wintmalt and the c- fertilization variant (LAV+HAKOFYT extra) - 8,34 t per ha was the best one for Malwinta. In the second monitored year 2009/2010, the d-fertilization variant - 8,49 t per haseemed to be the best one for Wintmalt and the c-fertilization variant - 8,57 t per ha for the second monitored genotype (Malwinta). In both monitored years, the lowest yield for both monitored genotypes was reached in the non- fertilization variant - a. Chemical indicator - extraction which varied from 80.16 to 80.90 %.
