To compare two methods for the establishment of pasture legumes (i) summer sowing where dormant hard-seed is drill sown into the paddock after the crop is harvested and (ii) traditional sowing where scarified seed is drill sown after the break of the season and knockdown weed control.
Traditionally, forage legumes are sown after the main cropping program is completed and require
the application of a pre-sowing knockdown herbicide to control established weeds. This treatment
seriously reduces early winter pasture production which is then compounded by the slow growth
rate of legumes under the cold winter conditions.
For further comments please see the attached trial report.
