The influence of chemicalization levels on yield and grain quality of zoned cultivars of spring wheat in the forest-steppe of Irkutsk region

The research objective was the determination of the dependence of indicators of productivity and quality of grain of six zoned varieties of spring wheat on using various levels of chemicalixation. The research problems were the determination of distinctions in productivity and quality indicators of grain between spring wheat varieties by options of field experiments made in 2016-2018. The objects of the researches were varieties of spring wheat of different origination and groups of ripeness zoned in Irkutsk Region. Grain quality assays were carried out in the laboratory of agrochemical analysis of Irkutsk Scientific Research Institute of Agriculture and in the Laboratory for Determining Grain Quality of Irkutsk State Agrarian University. .Among grain quality parameters the content of protein and gluten, the quality of gluten, test weight and hardness of grain and the weight of 1000 seeds were studied. As a result of observations it was revealed that due to genetic characteristics each of studied varieties had a different degree of responsiveness to the levels of chemicalization used in the trials...
