Genotype x management interaction for nutrient use efficiency (NUE) of maize varieties tested under different tillage and fertilization regimes Organic Eprints
Messmer, Monika; Uehlinger, Noemi; Berner, Alfred; Scholberg, Johannes; Mäder, Paul.
Most varieties have been selected under high input conditions, including seed treatment, herbicide applications, as well as optimal levels of fast releasing fertilizers. Under organic farming nutrient release is dependent on the temperature and biological activity of the soil and its interaction with the declining residues from previous crops and applied quantity of farmyard manure. As a consequence it is not always possible to match nutrient release with crop demand over time. This effect is even more severe under conservation tillage. To promote conservation tillage in organic farming, it is necessary to identify cultivars that show high nutrient use efficiency (NUE) under these conditions. While there is substantial evidence that breeding for low N...

Klimafreundlicher Bioackerbau auf mittelschweren Böden (Exaktversuche Aesch und Muri) Organic Eprints
Messmer, Monika; Berner , Alfred; Uehlinger, Noemi; Mäder , Paul.
Conclusion pour la pratique ❯ Lors de la conversion du labourage au travail réduit du sol, il faut s'attendre à de légères pertes de rendement en fonction du sol. Elles peuvent toutefois être compensées par des quantités d'engrais plus élevées ou une sélection adéquate des variétés. ❯ Avec le travail réduit du sol, il est particulièrement important de contrôler en temps utile le développement des mauvaises herbes. A ce propos, l'acquisition de machines spéciales est peut-être requise. Fazit für die Praxis ❯ Bei der Umstellung von Pflug auf reduzierte Bodenbearbeitung muss je nach Boden mit leichten Ertragseinbussen gerechnet werden. Diese können jedoch durch erhöhte Düngegaben bzw. mit geeigneter Sortenwahl kompensiert werden. ❯ Bei der...
