Low levels of natural light in greenhouses and a short winter day require additional irradiation, and artificial maintenance of temperature and humidity, due to the significant cost of non-renewable energy. It is known that about half of the cost of production is accounted for by electricity. Therefore, the state level is gaining issues of conservation of electricity spent on lighting and irradiation of plants. One of the ways to reduce the cost of electricity for light crops is to improve the methods of calculating photosynthetic irradiation, followed by automatic maintenance of the effective level of irradiation.
One of the ways to reduce energy consumption for photoculture of plants in protected ground structures and increase their productivity is to improve methods for determining and maintaining optimal illumination values with radiation of a given range, which will provide the most effective level of photosynthetic process of plant development with a subsequent increase in its productivity. In the given article, the modeling of the electromagnetic field of the optical spectrum at the level of plant leaf formation, which takes into account the scattered radiation and reflected by the surfaces of the walls and ceiling, is carried out. The proposed method increases the accuracy of determining the actual value of irradiance by taking into account the features of the brightness of the coating on the walls and ceiling and their reflection coefficient as a function of spatial coordinates.
An example is given of using this method to determine and automatically maintain the actual photosynthetic irradiation in accordance with the standard value of light intensity in the production room of the greenhouse, which ensures effective plant development and, accordingly, maximum productivity.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
