Extract

1. In an experiment conducted at the Hannah Institute the effects of irrigation and fertilizer nitrogen treatments on four sward types were studied for 3 years. The swards were S 23 perennial rye-grass with S 100 white clover, S 23 rye-grass alone, S 37 cocksfoot with S 100 white clover, and S 37 cocksfoot alone.

2. The irrigation treatments were—a control (no water) treatment, and two treatments which were irrigated to planned deficit levels of 2 or 0·5 in. below field capacity.
