Influence of some herbicides and herbicide combinations on the elements of yield and some quality indicators of winter barley (Hordeum vulgare L.) variety Obzor

Abstract

Abstract. In order to determine the impact of some herbicides and herbicide combinations on elements of yield in winter barley a field experiment was carried out under the block method, in 12 variants and 4 replicates using the herbicides: Granstar 75 DF, Derby Super WG, Secator OD; Lintur 70 WG, Stomp New 330 ЕC and Axial 050 EC. It has been found that the plants with the highest tiller productivity were the variants treated with Lintur 70WG and the combination of Secator OD + Axial 050 EC. The longest spikes were found in the plants treated individually with Secator OD. The largest is the number of spikes of plants treated with Stomp New 33 EC and the combination Lintur 70WG + Axial 050 EC. The herbicide combinations Granstar 75DF + Axial 050EK and Secator OD + Axial 050 EC imported into wheat seed provided the largest number of grains per spike. The largest grain weight per spike had a hand weeded control and herbicide combinations Granstar 75 DF+Axial 050 EK and Secator OD + Axial 050 EC.
