Анотация: In 2017-2019 the relative agro-biological effect of equal doses of mineral fertilizers, half rotten manure, granulated guano, organomix and that of the bacterial (Azoto + Phosphate Barvar) concentrates on the plants’ yield capacity and vegetative mass, as well as on the content of nitrates, total sugar, vitamin C and dry matters in the ripe fruits was investigated during the tomato and pepper field experiments in conditions of the Ararat valley. The highest effect has been observed in the mineral fertilizers (N150P80K150 and N150P80 kg/ha), half rotten manure (30 t/ha) and granulated guano (5 t/ha), while the lowest indicators have been recorded in the variants of organomix and bacterial concentrates after the control one. Within the three-year experiments the nitrate content in the mature fruits of the tomato variety “Lia” excessed the MPC value (150 mg/kg for the open ground), which seems to be a varietal characteristics.
