The Influence of Some Herbicides on the Structural Elements of the Yield of Winter Oilseed Rape

Abstract

In the period 2011-2013 in the experimental field of the Agricultural University, Plovdiv, were conducted field experiments using some herbicides Teridox (500 g/1 dimetochor), Butizan S (500 g/1 metazachlor), Modaon 4F (48 g/1 bifenox) on winter oilseed rape. The experiments were based on the block method over an area of 25 m2 in 4 repetitions. It has been established that they demonstrate excellent selectivity for this crop and by eliminating the competition of the weeds, they increase the components of the yield and have a positive effect on the growth and the development of rape. The obtained data has been statistically processed based on the Student method
