Note on the relative merit of four cultivars of Eragrostis curvula in Natal

Abstract

A series of trials showed that differences in hay yield of four cultivars of Eragrostis curvula (Ermelo, American Leafy, Kromdraai and Witbank) depended largely on the cultivar concerned and the ecological area in which the grasses were grown. Differences in the relative palatability of the four cultivars were small. The response to limestone ammonium nitrate as a source of nitrogen was greater than that to urea in the case of the Witbank and American Leafy cultivars.
