The studies were carried out in 2000–2002 on winter triticale, Bogo cultivar. The purpose of the field experiment was to evaluate the effectiveness of pro-ecological and chemical methods of weed control, expressed by winter triticale yield. Six methods of weed control were tested: mechanical, biological and chemical ones, two of each; mechanical – 1× and 2× harrowing, biological – straw of faba bean and spring vetch intercrop and straw of faba bean and buckwheat intercrop, chemical – Granstar 75 WG and Glean 75 DF. Three-years’ averages indicate that all applied methods of weed control protected winter triticale crops in a similar way (no significant differences were observed). The results indicate that the effectiveness of the applied methods of weed control was affected in a large measure by the fluctuating meteorological conditions. Besides, they simultaneously show that the mechanical methods of weed control are more successful when compared to the crop protection characteristics of soil-applied herbicides. The received crops can satisfy both the advocates of conventional farming as well pro-ecological farming.
