The development of Ukraine's agro-industrial complex significantly impacts the country's economy as a whole, especially during martial law. The products of the agro-industrial complex have a significant share in the volume of exports and are the primary representative of the revenues of the state budget of Ukraine. Therefore, the study of the diversification of sources of financing of the agro-industrial complex is relevant. This study aims to assess the latest trends in the development of the agro-industrial complex and develop recommendations for the development of the economy of Ukraine as a whole, taking into account the conditions of wartime. During the research, historical analysis, forecasting, and abstraction were used. As part of the study, statistical data for 2019-2023 were analysed, so the number of operating enterprises of the agro-industrial complex during the analysed period decreased by 31.45%. The latest trends in the development of the agro-industrial complex of Ukraine are characterized, and the main directions of its innovative and investment development are defined. Therefore, in martial law conditions, using a project approach to innovative investment financing of agroindustrial complex enterprises, which need exceptional support, becomes even more relevant. That is why separate recommendations were given regarding sources, modern technologies, digitalization, and directions for diversifying sources of financing for innovation and investment projects in the agro-industrial complex of Ukraine.
