Forage and Root Growth of Five Sweetclover Varieties and Their Influence on Two Following Corn Crops
1958
Pumphrey, F. V. | Koehler, F. E.
SynopsisSpanish, Evergreen, and Madrid sweetclovers differed little in dry matter production and nitrogen content in first- and early second-year growth and exceeded common white only in first-year growth. Hubam produced more forage, but contained no more nitrogen per acre. The biennial varieties did not differ appreciably in quantity of roots per acre. Nearly 90% of the roots were in the top foot. Nitrogen content of the roots decreased with increasing depth.
