- Intervention effect Seedling number per metre increased with seeding rate.
- Intervention effect The percentage of seeds producing seedlings declined as seeding rate increased.
- Intervention effect Stand survival in 1967 was significantly better at 98 seeds per metre than at 33 seeds per metre.
- Intervention effect Seedstalk height increased with wider row spacing.
- Intervention effect Row spacing did not affect protein content in the 1963 harvest.
- Intervention effect In 1964, crude protein percentage declined as row spacing increased.
