RESULTS OF ECOLOGICAL TESTING (EVT) OF LENTIL VARIETIES UNDER CONDITIONS OF ORDINARY CHERNOZEMS OF NORTHERN KAZAKHSTAN

Abstract

The relevance of the research lies in the fact that with the annual growing area under lentils in the North Kazakhstan region, the choice of officially presented varieties is relatively limited, while most of the crops are sown with foreign varieties. The scientifc research assumed a comparative environmental testing of lentil varieties of different origins (breeding centers in Kazakhstan, Russia, Canada). The research techniques involved field carrying outs at the station, as well as laboratory measurement of the structural parameters of lentil plants. According to the results of the study, small-seeded lentil varieties Aida and Viceroy were identified based on a set of indicators. The results obtained are justified by an increase in the yield of the studied varieties, phenological observations, as well as indicators of the yield structure. Determining the correlation between yield and structure indicators showed that the formation of lentil yield is largely influenced by the following indicators: the number of beans per plant, the number of grains per plant, the weight of 1000 grains and the number of grains in a bean. According to the analysis of the dependence of the yield structure indicators on the vegetation season, a high correlation ratio of connections was noted only with the height of attachment of the lower beans and the height of the plant, moderate closeness of connections with the weight of 1000 grains. The practical utility of the conducted research consists in obtaining reliable data on the ecological adaptability of individual lentil varieties on the chernozem soils of Northern Kazakhstan, with their potential use by farms to increase production levels.
