Description

Lotononis bainesii is valued for its ready acceptance by stock, high nutritive value and cold tolerance, but its utility has been limited by the inexplicably high year to year variation in its contribution to the farm feed supply. Pott et al. (1983) showed that lotononis is short-lived; the persistence of yield depends more upon seedling regeneration than upon vegetative replace­ment through nodal rooting. No continuous fixed stocking regime from 7 to 28 sheep ha-1 favoured lotononis (Poot and Humphreys, 1983), and this paper discusses the effects of vari­ations in seasonal stocking rate and of factors influencing the development of a buried crown in lotononis which favours its resistance to grazing.

Effects of Variation in Seasonal Grazing Pressure and Mechanisms of Adaptation to Grazing in Lotononis bainesii
