Abstract
2 native species, mulga oats (Monachather paradoxa) and silky umbrella grass (Digitaria ammophila) and 2 exotic species, wool grass (Anthephora pubescens) and buffel grass (Cenchrus ciliaris) cv. Biloela were sown in pots containing Charleville mulga soil. Applications of P equivalent to 125 and 250 kg superphosphate/ha at the 2-leaf stage produced the greatest response in buffel grass, with an increase in shoot growth, increased plant N and P contents, reduced root:shoot ratios and accelerated tillering; the other species responded similarly. Application of 16.8 and 33.6 kg N/ha produced no significant responses and retarded very early seedling growth. There were no N X P interactions
