AGROCLIMATIC ZONES AND YIELD OF AGRICULTURAL CROPS IN THE CHANGING CONDITIONS OF REGIONAL CLIMATE

Today there is enough scientific research to prove the impact of climate change on agriculture. However, no conclusive conclusion as what in store for agriculture, its potential will increase or decrease. Significant consequences are likely manifest themselves at regional level, and this requires additional further adaptation agriculture corresponding territory. The aim study assess changes agro-climatic indicators level. subject Komi Republic, located extreme northeast European part country. chosen methodology based statistical processing ten meteorological stations region 1960-2018 economic productivity gross harvest agricultural crops 1913-2018 due large amount data. Paired regression analysis used accurately interpret results. obtained mathematical models evaluated according Pearson coefficient, Student’s t-criterion, determination F – Fisher’s criterion, so that results were reliable. For some regions, may turn out be negative form a decrease food supply, others - positive, an duration growing season and, accordingly, crops. relevance because these positive especially characteristic northern territories. As result, it revealed four regions insignificant climatic over sixty-year period. An yield vegetables open ground showed increased from 36 314 tons per hectare, main crop potatoes decreased almost 3 times, but reason reduction acreage, not change. trend line potato yields whole shows upward 100-year performed paired between selected republic average direct relationship only season, sum daily temperatures. Consequently, currently impossible assert ongoing have significant Republic
