- Intervention effect Superphosphate increased annual phalaris yield each year.
- Intervention effect Superphosphate increased annual clover yield each year.
- Intervention effect Superphosphate increased annual total pasture yield each year.
- Association Phalaris yield response to superphosphate was mainly linear.
- Intervention effect In the final year, clover yield at SP188 exceeded SP375.
- Intervention effect Nitrogen increased phalaris annual dry matter yield only with superphosphate.
- Intervention effect Nitrogen increased total pasture annual dry matter yield only with superphosphate.
- Intervention effect Nitrogen did not increase total pasture yield in the final year.
- Observation Without nitrogen, SP375 pasture shifted from clover dominance in 1967–68 to grass dominance in 1970.
- Observation At SP188, pasture remained clover dominant after establishment.
- Intervention effect Nitrogen reduced clover dominance at the higher superphosphate rate.
- Intervention effect Nitrogen prevented clover dominance at SP188.
