Abstract
Purpose. To study the agroecological assessment of fertilizer systems for growing tomatoes. Methods. Field, analytical, mathematical and statistical. Results The complex analysis of tomato fruit by the quantity of their commodity, non-commodity and damaged products during growing in the conditions of a micro-dipole experiment was carried out. The accounting area of the plot is 5.2 m2, the total area is 234 m2 with 9 fertilizer variants. Conclusions It has been established that the yield of tomatoes with the use of mineral fertilizers increases the yield of marketable products and reduces the yield of non- commodity, while organic fertilizers affect the resistance of plants to the negative effects of pathogens. The highest yield of commodity products of tomatoes was under the conditions of mineral nutrition + mulch and under the conditions of systematic fertilization with organic fertilizers (humates), namely 9.8 and 9.3 kg / m2, respectively.

Key words: fertilizer systems, tomato, commodity and non-product products, open soil.
