In the course of the 2000-2011 years photosynthetically active energy periodic influence on productivity and biometric parameters of the spring wheat cultivars in the region forest-steppe zones is researched; pseudoperiodic character of these processes is proved. Necessary criterion for the production process stability is supposed. The results of modeling and forecasting the spring wheat productivity till 2030 are given on the example of Uzhur SCTS.
