Summary

1. The importance of uniform production of herbage for crop-drying is emphasized.

2. A replicated experiment is described which compared four crops, two annuals and two leys under four manurial treatments which included a control and three applications of fertilizer (3½ cwt. ‘nitrochalk’) distributed during the season in three ways.

3. Vetches yielded 2500–3000 lb. dry matter per acre of 28–30% crude-protein content in two cuts.

Barley yielded 2500–3000 lb. dry matter per acre of 18–21% crude protein in five to six cuts.

Leys yielded 4000–5000 lb. dry matter per acre of 15–18% crude protein in four cuts in their first year, and 5000–6000 lb. dry matter per acre of 15–18% crude protein in five cuts in their second year.
