The effectiveness of the use of chelated microfertilizers on the formation of green biomass of grain sorghum cultivated in arid conditions of the Saratov region

During the research period, morphological characteristics were measured in grain sorghum varieties of the FGBNU RosNIISK "Rossorgo" selection in order to identify the effect of chelated microfertilizers. The complex of agronomic features included the following indicators of grain sorghum productivity: plant height, length of the flag and largest leaf, biomass yield. According to the results of the research, the influence of chelated microfertilizers on the morphological characteristics of grain sorghum cultivated in the Saratov Volga region was revealed. Leaf treatment of vegetative grain sorghum plants had a significant effect on the height of grain sorghum plants from 3.3 to 5.2%, and also contributed to a significant increase in biomass by 17.3-27.6%.
