Abstract

Summary In 2008–2010 at the qualification of influence was the aim of investigations tillage systems and weed control methods on effectiveness of destruction of the weed air‐dry mass as well as the influence of damage herbicides applied in the blue lupine tillage. In 2008–2010 a field experiment was carried out at the Agricultural Experimental Farm Zawady of the University of Natural Sciences and Hummanities in Siedlce. The experiment was set up in split‐plot design with four replications. The aim of the study was to evaluate the efficacy of weed regulation in blue lupin crops with the use of: I – different tillage systems (conventional and simplified) and II – five weed control methods. Phytotoxicity of applied herbicides to the plants of blue lupin was also taken into consideration. The best results in weed controlling were obtained after the use of the herbicide mixture: Afalon Dyspersyjny 450 SC + Metron 700 SL + Fusilade Forte 150 EC at both dates of observations, and its efficacy amounted to 81.7 and 53.3% respectively. The results the studies revealed that the efficacy of weed regulation in blue lupin crops depended on such factors as tillage systems, applied herbicides and their mixtures and weather conditions.
