The Lower Eyre Peninsula survey showed most paddocks had internal blackleg infection levels below 10% unlikely to suffer a yield or oil content penalty... Current varieties have a number of resistance genes if blackleg overcomes one resistance gene, other resistance genes remain effective and so the crops should not become completely susceptible... Final grain yield after slashing was similar in all varieties (about 0.8 t/ha average), except CB1206 (0.2 t/ha)...

27.9: Tony Pratt: Technical officer, Farmlink Research, Temora NSW 29.349: Yes that is correct we are finding that harvest height in the southern region is having 34.62: impacts on grain yield at harvest time and it is also having some effects on crop emergence 40.72: in the following season... 133.29: Tony Pratt: By harvesting lower you're having to take 136.06: a lot more of the crop biomass and residue and this has resulted in a .14 tonnes per 143.24: hectare lost of yield... 192.069: Tony Pratt: We have a short harvest height of around about 195.89: 15 centimetres with the residue of the machine spread evenly across the harvest width...

WAWHT 2525A has metribuzin tolerance similar to Blade... When registrations are completed, wheat growers can manage barley grass, brome grass, silver grass, ryegrass, toadrush, wild radish, capeweed, doublegee and wire weeds in this variety by using metribuzin alone or its mixtures with trifluralin and diuron... In previous tolerance work, metribuzin/trifluralin has reduced yields by 30% at Mullewa (1997) and 37% at Merredin (1998), but by only 9% at Mullewa (1998) and 7% at Merredin (1997)...

" Print the page Wheat growers should aim for a plant population of about 1 million plants per hectare or 100 plants per square metre... In Queensland, over the last 20 years, plant populations of 1 million plants per hectare gave the best wheat crops under most conditions... Higher populations did not adversely affect yield, whereas populations fewer than half a million plants per hectare yielded significantly less (see Figure 1)...

Seeding rates theory holds water for repellent soils.. Topsoil water repellence was measured at all sites using the Molarity of Ethanol Droplet (MED) test... "At Yealering, the use of soil wetters increased the plant numbers over the control by at least 18 per cent at the 60kg/ha seed rate and 22 per cent at the 120klg/ha seed rate," he said...
