Weed control in winter triticale under reduced tillage.

摘要

In continuous cropping of winter triticale (cultivar Woltario) a number and biomass of weeds were significantly dependent on a soil tillage system and method of seed dressing. When grain was treated with seed dressing Galmano 201 FS the number and biomass of weeds in triticale stand were significantly lower compared to those found in triticale treated with Raxil 515 FS by 23.7% and 36.3% respectively. Compared to conventional tillage, the treatment with postharvest plowing and stubble crop but without presowing tillage showed 32% lower number of weeds. The lowest weed infestation in triticale was recorded in the treatment with Galmano 201 FS seed dressing and direct drilling of triticale, after previous full postharvest tillage in which white mustard stubble crop was desiccated with Roundup Max 680 SL.
