Biofertilizers application in agro-ecosystem improves the soil properties, protects the environment and has a positive effect on plants. As a result of the application of the studied biofertilizers, the plants heights in spindle phase are higher in all variants, compared to the control one. This difference is greatest at the treated with Baikal EM - 48.57 cm, which is 14% above control, followed by the one, treated with Amalgerol - 47.85 cm and Tryven - 47.73 cm. The positive effect on the studied biofertilizers on Triticum monococcum L., for good nutrition and intensive plant cultivation, is maintained until full density, where the highest values are reported at the variants treated with Lithovit - 99.6 cm (11% above control), Triven - 97.45 cm (8.8%) and Baikal EM - 97 cm (8.3%). The increase of the microbial activity in the soil at the variant, treated with Baikal EM (heading phase ) shows a trend that persists on the 7th, 14th and 21st day and has a positive effect on the plant height.
