Economic evaluation with biological growing of determinate tomato

Plamena Yankova, Hriska Boteva

Abstract: The research was carried out during the period 2014-2016 in the experimental field of department „Plant production” at Technical University of Varna. With determinant tomatoes, variety Nikolina F1 are tested biological products for fertilizing: Biosol, Biofa and Emosan with two plans of growing – single-row and two-row plan. The purpose is to be realized an evaluation of the economic efficiency by the fertilizing and the way of growing of moderately early tomatoes in the conditions of the biological production. The highest profitability and rate of profitableness average for the period of research is established with combined fertilizing with the combined feeding up with Emosan + Biofa, respectively 1.91 % for the one-row and 2.08 % for the two-row plan. A high effect is observed also with the fertilizing by the bio product Emosan. The high values of the economic indexes, in combination with the high average yield, determine the fertilizing with Emosan, put independently or combined with Biofa with both plans of growing as economically justified and appropriate for biological production of moderately early tomatoes.
