The article reveals the importance of land for the agricultural sector, as well as the state of weather and climatic conditions and their influence on the cultivation of agricultural crops. At the same time, it is reasonably emphasized that natural factors represent key factors affecting the economic viability of enterprises. The agricultural sector is more dependent on the climatic conditions than other industries and has a pronounced seasonal nature. It is noted that a significant part of the country’s territory is located in the zone of unsustainable farming. The stability of crop yields is decreasing from north to south of the country. That is why the southern zone of the country, including ATU Gagauzia, is located in the epicenter of unsustainable agriculture. This is evidenced by the indicators of yields of cultivated crops in various regions of the country. There are presented the yields of grain crops, sunflower and fruits in the whole country and in the regions for 2009-2017. Comparative yields of grain crops and fruits on average in the southern zone of the republic and ATU Gagauzia, located in the epicenter of high-risk farming, are also given. The material is presented in tables and graphs. There was conducted an analysis of the instability of the yield of these crops for the analysed period.
