VARIABILITY OF GRAIN YIELDS AND LEGUMINOUS CROPS IN KIROV REGION

The purpose of the research is to identify trends and factors variability in yield main agricultural crops Kirov region. study was conducted on basis data from territorial body Federal State Statistics Service for region 2001-2020. An analysis regression equations showed that dynamics analyzed period most accurately described by a 2nd degree polynomial. grain leguminous over twenty-year varied 12.6 21.7 q/ha. average five years 14.2 q/ha 2001-2005 up 19.6 c/ha 2015-2020 variation coefficient 8.6 15.5%, stability - 91.4 84.5%, respectively. highest achieved last years, due use intensive production technologies. In addition technology, productivity also affected agrometeorological origin. According results calculations, about 10% depends influence weather climatic conditions, respectively, 90% culture agriculture. calculations positive negative deviations actual dynamic average, it revealed increase favorable terms conditions can be 4.1 centners per hectare, shortfall unfavorable will 3.7 hectare. Calculation component according method Pasov V.M. belongs zone moderately stable
