The main objectives of the present work are to determine the ecological valence of the average yields of the following crops: wheat, barley, maize for grain and for silage, rye, triticale, sunflower and alfalfa in Bulgaria for the period 2001 to 2015. The ecological valence of agricultural crops is very important because it is related to their spreading in different soil and climatic conditions. The main method by which the results are obtained is the single-factor analysis of variance (ANOVA)fatcat:sdlijt4g4vbyvnhgzpomgeie3y
