The influence of soil tillage and weed suppression at winter wheat yield

Modern soil tillage systems, based on different tools than mouldboard plough, have very often stronger weed occurrence, which can be serious problem for achieving high yields. Obvious solution for weed suppression are herbicides, whose improper use can deteriorate environment and lead toward serious ecological problems. In order to investigate interaction between soil tillage and herbicide, trial has been set up in Valpovo in seasons 2008/09 and 2009/10. Two soil tillage systems (CT-conventional tillage, based at mouldboard ploughing, and CH-chiseling and diskharrowing, without ploughing) and four herbicide treatments {; ; ; [H2-recommended dose of Herbaflex (2 l ha-1) ; H3-half dose of Herbaflex ; H4-recommended dose of Fox (1, 5 l ha-1) ; and H5-half dose of Fox)] and H1- controle, no herbicides}; ; ; were applied in winter wheat. Results are suggesting similar effects of soil tillage at the winter wheat yield, whereas all herbicide treatments showed higher weed suppression and winter wheat yield, in comparison with H1 treatment.
