The effects of height of stubble left after simulated rotational grazing on regrowth of star grass

Abstract

Star grass (Cynodon aethiopicus cv. No. 2) was grazed to leave stubble of 5, 15 or 25 cm in height after grazing. In the first year (1972–73) 350 kg N and 39 kg P per ha, and in the second year (1974–75) 500 kg N and 39 kg P per ha, were applied. Grazing was done at 15‐day intervals although in the first year this was not always possible because of poor rainfall which affected growth.
