During the period 2012-2013, a study was made on the effect of using deep-water organic-mineral sediments (sapropels) of the Black Sea as amendment for alluvial meadow soil (Calcaric Fluvisol) – manure substrate used for seedlings production of eggplant cv. Patladjan 12. The results obtained after two years of field experiments showed that the introduction of 30 g/kg of Black Sea sapropels increases the pH of soil-manure substrate from 7.42 to 7.74 units and improves the growing parameters of eggplant seedlings as follows: the height of the central stem by 9.20%, the width of the central stem by 0.98% and the number of leaves by 8.15%. According to the field experiment, the early standard yield of eggplant fruits increased by 14% for the plants grown in Variant I and the total standard yield - by 10.6% compared with the control variant.
