The article presents the study of biochemical indices of strawberry varieties Honeoye,Elsanta,Sharlotte and Bettyby improving water quantity management of the drip irrigation system in relation to climatic conditions rainfall, air temperature, air humidity, evapotranspiration, solar radiation and the presence ofwind). Muchat tention was paid to the main biochemical parameters such as weight of dry substance and carbohydrates content. The best quantitative and qualitative results of strawberries have been obtained in the case of Honeoye variety(variant 1 – maintaining the humidity of 75% of soil’s field capacity).
