Abstract

A new seeding technique - press the seed, not the soil - was developed, tested and demonstrated in comparison with the conventional methods of seeding using press wheels and harrows on lupins. The lupin seed was pressed into the soil but the soil was left relatively loose above the seed (no ryegrass-seed soil contact) as compared to firming seed and soil together by press wheels.

The new seed pressing gave excellent results in terms of early plant vigour, crop growth and establishment, ryegrass suppression and yield in a range soil-moisture environments in western Australia. During 1997 and 1998, lupin yield improvement up to 20% (on an average 10%) with 58% ryegrass suppression have been observed in field experiments.
