Abstract

Indian bluegrass for soil conservation and land stabilization in Queensland.

Abstract

2 evaluation trials were established in 1978 at Amberley near Brisbane to select suitable grass spp. for land stabilization. Bothriochloa pertusa cv. Bowen was the most promising grass amongst the spp. evaluated, although Digitaria scalarum and B. insculpta showed great potential. Adaptive characteristics of B. pertusa included rapid early development of an effective nodal root system, adaptation to a wide range of soil types, tolerance to drought and fire, good seed producing ability and low maintenance requirements. It could be established on various substrates including mulch, cover crop and fine seed bed. It was quite sensitive to frost and shading. Weed control was necessary to promote early establishment.
