Abstract: The article aims to disclose the results of implemented experiment seeking to establish bio fertilizer’s influence on the productivity of greenhouse tomatoes (variety Fado F1). Through a comparative economic analysis is determined the optimal bio fertilization using system of indicators for this purpose. Optimal fertilization and its economic efficiency were assessed in strictly controlled factors, under which runs the experiment. The results of the economic assessment are valid only for the conditions under which experiment were performed. Through statistical analysis is determined the perfect combination of bio fertilizes that ensure the highest rate of productivity. The analysis is going further by measuring the highest economic effect of embedded system of bio fertilizers expressed by standard economic indicators like gross margin, gross profit and cost-effectiveness. The bio fertilizers used in the experiment has a positive impact on the productivity of greenhouse tomatoes variety Fado F1. The productivity of this type of fertilizers is higher to that achieved by the use of conventional mineral fertilizers.
