Abstract

The article deals with the influence of the planting depth of potato tubers on the photosynthetic activity of potato plants in the conditions of the Chuvash Republic. The depth of seeding of tubers has a direct impact on all processes of growth and development. The more favorable conditions in the zone of placement of planted tubers, the faster they germinate and give early and amicable shoots, the more successful the further development of the potato plant and the formation of the crop. The establishment of the dependence of the planting depth of potato tubers on the photosynthetic activity of potato plants makes it difficult for a variety of reasons that are directly related to the photosynthetic activity of the potato plant, since the potato plant productivity is significantly increased by optimizing the priority conditions that are necessary in the the potato plant cultivation, when all the photosynthetic activity potato plants. In this study, in order to determine potato productivity, optimal parameters of photosynthetic parameters, such as leaf surface, net photosynthesis productivity, and the FAP utilization coefficient were determined in the first study. The assimilating surface of the leaf surface of plants, per unit of sowing area, determines the absorption of phage by plants. Optimal leaf area, according to L.G. Shashkarov (2006), for potato plants is the surface up to 40 thousand square meter.
