%X Aerial sowing is the only option for introducing improved pasture species into much of the non-arable, acid soil rangelands in central New South Wales. However, low germination of seeds in serradella pods is a major problem causing poor establishment. Sowing different combinations of pod and seed was investigated as a means of improving germination and subsequent persistence in an experiment between 1993 and 1997. Results indicated that a pod:seed mixture of 75:25 was the most suitable ratio for establishing yellow serradella (Ornithopus compressus) when broadcast into native grassland on hardsetting, non-arable, acidic hill country. Nodulation failure observed at this cold tablelands site confirmed the need for a more winter-active inoculant for yellow serradella.
