The transition to alternative growing technologies for forest planting material is determined by significant climatic changes and growing demand for woody plants, resistant to unfavorable factors. Development and practical application of innovations is constrained by the lack of investment and information on the economic efficiency of the use of innovative technologies. Container technologies for the production of planting material in tree ornamental nurseries occupy an increasing segment of

... ern market in Russia and foreign countries. The innovative Pot-in-pot technology combines the advantages of container and soil cultivation of woody plants material. In the article, using cost-effective method and economic feasibility of innovative technology for seedlings' growing has been determined. Investment analysis method, based on estimates of net present value, discounted payback period, and rate of return on invested capital, is used to assess the cultivation of seedlings using innovative Pot-in-Pot technology. The study has made it possible to determine the costs of growing spruce seedlings using Pot-in-Pot technology and economically substantiate the effectiveness of an innovative solution for growing planting material. The use of Pot-in-Pot technology in forestry practice can provide a breakthrough in growing seedlings, resistant to the harmful effects of high temperatures and low moisture requirements. Along with biological effects, the use of technology in forest nurseries can reduce production costs and ensure the economic effect of mass production of seedlings. The adaptation of Pot-in-Pot technology to the conditions of forestry in Russia will accelerate the processes of reforestation in changing climatic conditions, primarily through the production of sustainable planting material with a relatively low cost of cultivation.
