Glyphosate application and direct sowing of winter wheat considering soil cultivation history
In a two year field trial (2013/2014 and 2014/2015) the possible impact of glyphosate application on winter wheat after direct sowing was investigated. Glyphosate was applied with single and double application rates seven days before sowing and until five days after sowing. For comparison a mechanic...

| Summary: | In a two year field trial (2013/2014 and 2014/2015) the possible impact of glyphosate application on winter wheat after direct sowing was investigated. Glyphosate was applied with single and double application rates seven days before sowing and until five days after sowing. For comparison a mechanical treatment with flat cultivator and rotary harrow was created. The trials were carried out on an agricultural field with plots of three different soil cultivation history (conventional = plough, reduced = mulch sowing, direct sowing = direct sowing with glyphosate application). Plant emergence and yield of winter wheat was investigated. Conventional soil cultivation history showed highest plant emergence and highest yields in both years. Lowest plant emergence was estimated in trials with flat cultivator and reduced or direct sowing soil history. Treatments with glyphosate application before and after sowing showed no significant yield differences. At a double glyphosate application rate, plant emergence was lower in comparison to the single application rate in most cases in 2013/2014. This was also estimated for glyphosate application after sowing in 2014/2015. |
