Other claims from this paper (19)
- Intervention effect Applying 225 kg N/ha per year depressed white clover yield by 38%.
- Intervention effect Applying 225 kg N/ha per year depressed clover proportion in the sward by 45%.
- Intervention effect Applying 225 kg N/ha per year increased total sward yield by 27%.
- Intervention effect Applying 25 kg N/ha per year had no significant effect on clover or total sward yield.
- Observation Huia, Kopu, Bianca and Crau had the highest spring N tolerance ratio among white clover cultivars.
- Observation Menna, Aran and Katrina had the lowest spring N tolerance ratio among white clover cultivars.
- Observation Spring N tolerance ratio is not correlated with spring yield or the stolon characters measured.
- Association Total sward yield was significantly related to clover yield when 25 kg N/ha per year was applied.
- Observation No significant cultivar by N interaction was found for clover yield or proportion of clover in the sward.
- Observation No significant cultivar by N interaction was found for stolon characters.
- Observation Large differences exist among white clover cultivars for clover yield, total sward yield and proportion of clover in the sward.
- Observation Menna, N-line, Kersey, Katrina and Tahora had the lowest clover yields among white clover cultivars.
- Observation Swards containing Crau had significantly higher total yields than most other cultivars.
- Observation A significant cultivar by season interaction was found for clover yield and proportion of clover in the sward.
- Observation G.23 had the highest proportion of clover in the cool autumn-winter period.
- Observation Crau was highest in proportion of clover in the warmer summer-autumn period.
- Observation Aran, Olwen and Demand had high summer clover contents.
- Observation Kopu had high winter clover contents.
- Observation No significant differences among cultivars were found for N tolerance ratio for any stolon characters.
