R.  aEffects of soils, fertilizers and stocking rates on pastures and beef production on the wallum of south-eastern Queenslandb2-Liveweigth change and beef production.h[electronic resource]  c1973  aAnimal production was measured over a six-year period from grass-legume pastures receiving different maintenance rates of phosphorus and potassium fertilizers, and continuously grazed at stocking rates of 1.23, 1.65 and 2.47 beasts ha -1. The pastures consisted of the grasses Chloris gayana, Digitaria decumbens, Paspalum dilatatum and P. commersonii and the legumes Desmodium intortum, D. uncinatum, Lotononis bainesii, Macroptilium lathyroides and Trifolium repens. Annual applications of 250kg ha -1 superphosphate (9.6 per cent P) significantly increased animal production above applications of 125kg ha -1 superphosphate, but there wereno significant effects of increased in level of applied potassium (as KCL) beyond 63kg ha -1. (Cont.)The greatest liveweight gain per hectare was obtained at a stocking rate of 2.47 beasts ha -1 but rate of liveweigth change was more variable than at the other stocking rates. Conversely, daily liveweight gains per head and rate of turnoff were greatest at 1.23 beasts ha -1. Both stocking rates and levels of superphosphate affected quality of carcase produced, and there was a significant positive correlation of liveweigth gain and legume content of the pastures.  asoil  aCarne  aProdução  aFertilização  aPastagens  aSolos1 aBRYAN, W.
