- Intervention effect Fertiliser N application increased total annual pasture production by 25–31%.
- Intervention effect N application reduced white clover production by 8, 17, and 30% in Years 1, 2, and 3 respectively.
- Association In the nil N treatment, clover production and total pasture production were positively correlated in Years 1 and 2.
- Observation Aran and Kopu were higher yielding than all other white clover cultivars.
- Observation During winter, Kopu was 2–5 fold more productive than other white clover cultivars.
- Observation In all other seasons, Aran and Kopu were the most productive white clover cultivars.
- Mechanism Aran and Kopu maintained a lower associated grass component in their swards.
