e0“plant numbers rose but percentage survival declined as seed rate was increased”
t0“The influence of date of sowing and seed rate on the production of pure‐sown red clover”
t1“August and September sowings gave the lowest red clover contents in a range from 63.2 to 96.5%, the highest digestibilities within a range 61.9 to 65.0% and the lowest crude protein contents in a range 15.5 to 17.3%.”

Other claims from this paper (14)
- Intervention effect April to July sowing produced significantly higher yields than later sowing.
- Intervention effect August and September sowing gave the lowest red clover contents.
- Intervention effect August and September sowing gave the highest digestibilities.
- Intervention effect August and September sowing gave the lowest crude protein content.
- Intervention effect Higher seed rate increased annual total herbage dry matter yield from 9.88 to 10.85 t ha −1.
- Intervention effect Red clover dry matter yields followed the increasing seed rate trend.
- Intervention effect Red clover content followed the increasing seed rate trend.
- Intervention effect Crude protein content followed the increasing seed rate trend.
- Intervention effect Late sowing depressed spring plant numbers and survival.
- Intervention effect Higher seed rates decreased percentage survival.
- Observation Seed rate effects on population persisted into the second harvest year, unlike sowing date effects.
- Recommendation The authors recommended April to June sowing with 12 kg ha −1 seed rate.
- Observation Increasing seed rate could not fully compensate for late sowing.
- Association Seed rate and sowing date had a significant interaction.
