Productivity of winter rye depending on the herbicides used

At present, winter rye is cultivated on a much smaller area than in former times. At the same time, this crop is of universal value and can be used for food as well as for fodder and technical purposes. Like other agricultural plants, winter rye suffers from weeds, although it has a fairly high competitive ability. In this regard, the use of herbicides is justified. In studies it was found that on crops of winter rye with mixed type of weed infestation the most justified is the use of herbicide Magnum, as the men- tioned drug provides reduction of weed infestation by 80% in number and by 82% in mass. The freedom from competition from the weed component of agrocenosis contributed to an increase in grain yield by 0,16-1,17 t/ha, and the highest yield was obtained when using Nivoros herbicide (10 g/ha) - 3,57 t/ha. The use of herbicides in winter rye allows not only to reduce the weediness, but also to improve the chemical composition of the grain. At the same time, the highest values on the set of indicators were observed in the variant with Nivoros herbicide (10 g/ha). The use of herbicides on winter rye allows to reach the level of profitability 21.3-63.6 %. The high- est level of profitability - 63.6 % was obtained in the variant with Nivoros herbicide (10 g/ha).
