The effect of the complex fertilizer APAVIVA NPK(S) 15:15:15(10) on the yield and biometric parameters of various varieties of endive lettuce (Cichorium endivia L.) was studied in controlled conditions of a pot experiment. The phytolaboratory maintained optimal temperature, humidity and lighting. UnionPowerStar-40W-T lamps were used in the experiment, diode wavelength: blue (450 nm), red (660 nm). Daylight hours were 15 hours (from 7-00 to 22-00). The application of APAVIVA led to an increase in plant height, leaf rosette diameter, number of leaves and their assimilation surface. The use of mineral fertilizer led to an increase in plant productivity. However, increased mineral nutrition contributed to an accelerated transition to the generative phase of plant development, the formation of flowering shoots and the outflow of nutrients from the leaves to the stem. This had a negative impact on the yield of marketable products - chicory lettuce leaves. The addition of lime material (dolomite flour) together with mineral fertilizer increased plant productivity as well as helped to inhibit the accelerated transition to the generative phase and increase the yield of leaf mass.
