Eight soybean varieties from Moldovan selection were traced in terms of productivity and its determining components in a three-year field trial. They have been compared with the Bulgarian standard variety Avigeya. The experiment was conducted in the period 2019-2021 in the condition of North Central Bulgaria at the field of Experimental station of soybean and grain crops, Pavlikeni, under non-irrigated conditions, with the standard for our country technology for growing soybeans. According to the results, in the studied group of varieties a significant genotypic diversity was observed for the selected morphological indicators during each year of experiment. The yields of soybean grain from Moldovan varieties and Bulgarian standard was greatly influenced by the weather conditions of the agricultural year. The significance of the genotypic effect in relation to environmental condition of agricultural year is less pronounced. Relatively high and stable year-round values for plant seed yield are observed for varieties Indra, Amedia and Aura. The same is observed for the indicated varieties with regard to the indicators harvest index and seed yield per decare. In general even in the condition of dry summer in non-irrigated cropping in Bulgaria and Republic of Moldova possess a great soybean cropping potential and could increase it.
