The article is devoted to the economic development of landowners in the Kazan province during the era of serfdom. The source base of the study contains published memoirs of representatives of the nobility, statistical publications, pre-revolutionary studies of the state of agriculture in private farms, as well as archival material containing economic descriptions of 12 districts of the province, compiled by local leaders of the nobility and individual landowners based on the questions of the questionnaire of the Free Economic Society in 1802. The author analyzed the natural and geographical factors that influenced economic life on the estates; characterized the working inventory and showed attempts to modernize it; studied the specialization of estates and identified the economy-forming industries; considered the features of the corvee and quitrent systems of peasant exploitation. In addition, the article shows examples of organizing market-oriented agricultural production. A conclusion is made about the subsistence nature of the landowner economy in the Kazan province in the pre-reform period, in which the sale of surplus did not mean the commercial nature of production. The availability of free labor deprived the incentive to introduce improved methods of land cultivation – use modern equipment, improved varieties of crops, as well as develop industries such as livestock and crop production.
