Description
Summary:	In this work, the contribution of the group of main agroecological factors to the final yield of spring barley was assessed using the model of principal component method and multivariate regression. It was found that in the conditions of the forest-steppe zone of Tatarstan the most significant factors are the group of variables that determine the conditions of heat and moisture availability, namely: the amount of precipitation during the growing season, the amount of temperature during the growing season, morphometric parameters of slope steepness and exposure. The method and depth of tillage did not have a significant effect on the final yield, as well as a number of other variables analyzed: forms of fertilizers used, predecessors in crop rotation, etc. Such variable as Exposition was not significantly related to Yield. With Pearson correlation method R=0.30 units, which is not reliable at n=31, but Exposition had a significant effect on Temperatures > 10 and Precipitation (R=0.78 units and -0.77 units), the strongest and most important factors in the formation of Yield. The information obtained will be very valuable in the development of management approaches, rational agro-technologies and adaptive systems.
