The requirements for safe and quality agricultural production impose changes in the models of fertilization and the use of organic products as an alternative to the application of chemical products. During the period 2015-2017 in the experimental field of IASS "Obraztsov chiflik" - Ruse was conducted biological trial with crop rotation, including the alternation of cereals (wheat and oats) and legumes (field beans and field fodder peas) crops under block method in four replications, with the size of the harvesting plot 10m2, including four variants of individual and combined application of biological products. The aim of the study was to study the effect of the bioactivator Euroradix (100 g da-1 in legumes applied with sowing), the biostimulators Euroactiv agro (250 g da-1 in cereals applied with sowing) and Amminostim bio (250 ml da-1 twice during the growing season in cereals and legumes) in individual and combined application on the yield of wheat variety Venka 1, field beans variety Obraztsov chiflik 12, spring oats variety Alexi and spring fodder peas variety Ruse1. In all crops, all tested variants with application of bioproducts showed higher yields compared to the control. The highest yield at cereals was registered in the variant Euroactiv+Amminostim bio, at legumes in the variant Euroradix+Amminostim bio at different climatic conditions and during the three years of testing.
