The paper studied an influence of fine irrigation on tea plants yield, physiologicalbiochemical and leaf anatomical and morphological parameters in Adygea conditions. The high efficiency of this irrigation method was established: yields have increased on average by 65 % over three years and amounted to 56.25 c/ha. The main indicators characterizing water regime state in tea plants were determined: cell sap concentration during the whole tea harvesting period and within irrigation was in the optimal values (8.0 ±1.0 %), whereas without irrigation it increased to 12.5 %, indicating a lack of moisture; water deficiency in leaves at the end of tea harvesting was 15.74 ±2.23 % in the control, whereas under irrigated conditions it was 6.66 ±0.35 %. Under the influence of irrigation, photosynthesis intensity increased 1.5−2.4 times. A comparative analysis of tea leaf anatomical and morphological traits showed a significant increase in the assimilation surface,
