Optimization of spring barley cultivation technology in the Chernozem region

In the conditions of the Central Chernozem region of Russia, an optimized technology for growing spring barley of the "Vakula" P4 variety was tested. Optimization of the technology was carried out according to the weed control element in five variants, depending on the use of herbicides: Puma Super (farm technology), Ballerina super (optimization), Prima (optimization), Ballerina forte (optimization), Lancelot (optimization). The conducted studies have shown that perennial and annual dicotyledonous weeds have a significant distribution in spring barley crops in the conditions of the Central Chernozem zone. Of these, according to the abundance indicators, white mar, medicinal dymyanka, white sandman, bindweed mountaineer, field yarutka, yellow osot, frankincense pickle predominates. A comparative analysis of optimization on the impact on plant productivity revealed that the most effective technologies for a wide range of weeds were technologies using herbicides Lancelot, Ballerina Super and Ballerina Forte. The highest barley yield of 34.4, 32.3 and 33.7 c/ha, respectively, was noted on these variants of technology application.
