The authors presented the results of the influence of stress factors on the yield of garden strawberry remontant large-fruited. Phenological and morphological observations, recording and evaluating the quality of the obtained fruits were carried out during the research. Varieties of remontant strawberries with a complex of economically beneficial features were identified. There were features as high yield, winter hardiness, resistance to major diseases and pests were presented. The obtained data confirmed that the highest productivity per bush showed varieties bearing fruit during the entire growing season: Selva - 376.06g, Vima Rina - 411.27g, Remontant large-fruited (hybrid) - 425.42g.

The need to obtain consistently high yields of agricultural plants in the Siberian Federal District is sufficiently high. Therefore, this work aimed to study the influence of protective structures on the growth, development, and productivity of tomatoes in the Novosibirsk region. The data obtained allow concluding that the use of protective structures protects plants from recurrent frosts, gusts of northern winds, and a sharp drop in temperature. Plants grown in standard protective structures, in the first periods after planting at a permanent place of growth, were subjected to stressful situations, which led to a decrease in the immunity of the plant and, as a result, damage by fungi and bacteria.
