Application of herbicides and their mixtures in brewing barley crop

Abstract

The studies were carried out in 2010 Roki skis distict, Pandelis env., Panemunis village, the farm of Paulius Martinonis in the brewing barley crop. The influence of herbicides and their mixtures application on brewing barley grain yield and it’s quality indexes, weediness have been studied. The studies revealed that in the brewing barley field dominated: common wormwood (Artemisia vulgaris), white goose-foot (Chenopodium album), field penny-cress (Thlaspi arvense), stickyweed (Galium aparine), wild radish (Raphanus raphanistrum), field thistle (Cirsium arvense), shepherd’s purse (Capsela bursa-pastoris). For investigation the frame of 0.25 m2 size was used in four places for each replication. The evaluation of the obtained data revealed that both the applied herbicides and their mixtures as well had a substantial impact on brewing barley grain yield, thousand grain weight, germination energy, weediness reduction. However, herbicide or their mixtures application had no effect on brewing barley grain crude protein. Herbicide mixtures application has been the most effective.
