Other claims from this paper (5)
- Intervention effect Reseeded swards produced significantly more herbage dry matter than permanent swards in the first year at all nitrogen treatments.
- Observation The Lolium perenne reseed production advantage persisted in later years only at higher nitrogen rates.
- Observation Sown Lolium perenne and Trifolium repens was the most productive sward at zero nitrogen.
- Observation Modified acid detergent fibre differences suggested a small quality advantage for reseeded swards.
- Recommendation The authors conclude reseeding to Lolium perenne cannot always be justified, especially with low or moderate nitrogen input.
