And those on alkaline soils...
GroundCover™ Issue: 28
Two groups of growers from low- and mediumrainfall areas of southern NSW, Victoria, SA and WA who farm on alkaline soils presented their wishlist at a workshop in Adelaide.
Growers from both rainfall zones said they required hard economic information about the benefits to profitability by having annual legume pastures in a rotation.
Farmers in the 350 mm-plus rainfall zone want a 100 per cent soft-seeded annual legume pasture variety.
They want a variety that will establish readily, be reaped for seed, and not regerminate in the following year's crop.
Currently such commercial doesn't exist causes problems in pulse crops when the pasture cannot be sprayed out without affecting the pulse.
But more hard-seeded varieties which can survive false breaks and carry seed supplies through a cropping phase remained on the whishlist as well.
Screening and breeding for disease resistance remain high on the agenda, as do varieties that maximise dry matter production, those which perform well in boron-toxic soils, those which will establish well in heavy stubbles and have better early vigour, and new lines which can be reaped with conventional headers.
Ease of harvesting and disease (root lesion nematode) avoidance were also high priorities for growers in the below 350 mm rainfall zone, also dominated by alkaline soils.
They also called for varieties with more ability to recover quickly from moisture stress, and those with greater pest tolerance, particularly to blue-green aphids.
