The basis of this article is the study of such a form of farming in rural areas as personal subsidiary farms (PSF). The importance of private farming is actualized both in matters of a social nature in rural areas and issues of sustainable development of entire sectors of the economy. The article clarifies the main socio-economic functions of individual subsidiary farms. The basics of motivation and goal setting for entrepreneurship are considered. And in this regard, a model is given for increasing the business activity of personal subsidiary farms based on small-scale poultry meat production. The model is described both from the point of view of the mechanisms of interaction of participants and from the organisation's point of view. The financial mechanisms of this model and its features are also given. Many economists consider PSF the most massive, and economically stable; one might even say the surviving producer of agricultural products sustainably. This phenomenon lies in the economic nature of PSF. In these conditions, personal subsidiary farms are additional for those who are engaged in hired work. For the majority, this is about 3 million people who are considered "self-employed", the only source of income. Of particular interest is the financial model of this project, which was developed by the project's authors and tested for three years. This model allows you to reduce the price of finished products and keep it 15% below the market. The project showed that personal subsidiary farms without special conditions could not transform massively into individual entrepreneurs or peasant farms. To do this, the state needs to organize prototypes of such operators on the ground, which will begin to perform all intermediary functions to improve the business environment of each rural locality.
