Barley is an important food and industrial crop in Romania and the choice of varieties is one of the most important decisions in the barley crop management because it greatly improves the production obtained in the ecological farming system and not only that. The aim of this study was to compare how some barley varieties differ in physiological traits and yield under organic farming conditions. This study was conducted in three different area from Romania throughout 2023-2024 winter wheat season. In one of the three localities the soil is acidic so another goal was to highlight the genetic variability among barley genotypes, to identify barley genotypes tolerant to acid soils using stress indices and to assess the association among stress indices as well as grain yield. The results showed that in the three location, the chlorophyl content, the height of plants, leaf area index and dry matter were highly variable. The grain yields were positively correlated with chlorophyll content and biomass, at a significance level of 0.01. Assessment of acid soil stress indices was also found to be promising in identifying tolerant genotypes with good yield potential. Based on these results, high-yield barley varieties may be choise to be cultivated under organic agriculture under climate change conditions from Romania.
