Einfluss verschiedener Saatstärken auf Winterweizen

Summary translation

The impact of different seeding rates (100, 200, 300 and 400 viable grains per m²) on grain yields and quality of winter wheat were examined in field experiments over four growing seasons at one experimental site in Bavaria. The yield dropped as soon as the sowing density was reduced to 200 viable grains per m². In contrast, quality parameters were better with reduced sowing densities. But all reduced sowing density was accompanied by a higher risk of weed infestation and a corresponding reduction in yield due to lower soil coverage and lower stand densities. Ultimately, the recommendation for practice remains to choose a relatively high sowing rate, as this represents a risk minimization particularly for years in which no sufficient weed control can be carried out.
