Establishment is a critical phase of crop growth. Poor establishment compromises early crop vigour and represents an economic loss from wasted seed. Currently little is known about the levels of crop establishment achieved by growers in commercial crops. One hundred and forty three paddocks were surveyed across the southern and western GRDC regions. A questionnaire was distributed to cooperating growers. Average establishment was 59% in canola, 82% in lentil and 64% in wheat. Separating seed and fertiliser delivery improved establishment in canola and lentil and using paired rows improved establishment in lentil. Other practices that affected crop establishment included time of sowing, depth of sowing, stubble cover and calibration method. The influences of these practices on establishment are described.
