Abstract

Relevance. Currently, there is an acute problem of meeting the growing demand for berry and fruit products. One of the ways to intensify agricultural production in the field of horticulture and crop production is to increase the efficiency of environmental management through the use of resource-saving technologies. One of these technologies is drip irrigation, which improves the quality of crop production.Materials and methods. Field studies were carried out on the territory of the educational and experimental farm of the laboratory "Michurinsky Garden" of the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy. The experiment was established in the fall of 2018 and is a two-factor study of various levels of moisture on the growth and development of raspberry seedlings. The first factor included options for maintaining soil moisture in the range: 1) control (without irrigation); 2) not less than 60% of the lowest moisture capacity; 3) not less than 70% of the lowest moisture capacity; 4) not less than 80% of the lowest moisture capacity. The second factor was the raspberry varieties Solnyshko and Nagrada.Results. Constructed moisture contours according to the study options showed that drip irrigation contributes to the optimum moisture concentration in the soil for seedlings. The most developed root system in comparison with the control was obtained on irrigated variants with maintaining a moisture content of at least 70 and 80% of the lowest moisture capacity. Here, the maximum values of the volume of the root system, the number of roots, and the average length of the root were obtained. It was revealed that in variants with irrigation, the root system of seedlings spreads in the upper layer (mainly 5-15 cm).
