GRDC Taxonomy:
" Nutrient removal - the hidden cost of chaff windrow burning Peter Newman, Department of Agriculture and Food, Geraldton carts and KEYMESSAGES The value of nutrients removed in a chaff cart when harvesting wheat in 2011 was $13/ha compared to $43/ha for windrow burning... The analysis suggests that lupin residue contains higher levels of potassium than cereal or canola; this is from a small number of samples only... The cost of a unit of potassium was estimated at the time of writing and will vary considerably...

National Adaptation and Mitigation Initiative (NAMI) funded by the Department of Agriculture and Food Western Australia, the Grains Research and Development Corporation and the Australian.. Government's Climate Change Research Program for funding the work.. Dry seeding is increasing including wheat...
GRDC Taxonomy:
Classic ripper uses one main tine to rip the soil to the required depth... Treatment SLT D (two SLT tines18 and 23 cm deep in front of a 33 cm main tine) also showed a decrease in draft force relative to the classic treatment but the decrease was not statistically significant and below those of treatments SLT A and SLT B. Both the treatments SLT C (one 18 cm SLT in front of a 33 cm main tine) and the SLT Offset treatments showed an increase in draft force relative to the classic treatment... The other two SLT treatments, SLT C and SLT D showed an increase in specific draft force of 5.33 kN...

Soil water under pasture-cropping with subtropical perennials Phil Ward, David Ferris, Roger Lawes, Perry Dolling, Shayne Micin, Nicola Palmer, and Phil Barrett-Lennard.. Winter tolerance of sub-tropical grasses commonly used agricultural herbicides John Borger and David Ferris to.. Water Dynamics & Grain Yield Results Crop growing season - little difference in soil water under annual crop, perennial pasture and pasture-cropped plots Grain fill - pastures started competing with crop impacts on grain yield were generally small but Summer and Autumn - soil water contents were much lower unde...
tan spot) is an important foliar disease of wheat in Australia and can cause losses exceeding 50% when conditions are favourable for disease development... A few lines within each population consistently showed high levels of resistance probably resulting from a combination of several genes with additive effects... Newly developed fixed lines with different gene combinations were evaluated in the field at South Perth in 2011 and twelve lines with gene combinations that increase genetic gain for APR to leaf blotch were identified...
GRDC Taxonomy:
" Taking soil acidity seriously - results of grower surveys Chris Gazey, Department of Agriculture and Food, Northam, Western Australia James Fisher, Desiree Futures, York, Western Australia Joel Andrew, Precision SoilTech, Belmont, Western Australia KEYMESSAGESFORGROWERS Aim to apply sufficient agricultural lime to achieve the target pH Caof 5.5 in the surface and 4.8 in the subsurface as an integral part of farming practice-this will ensure that soil acidity is removed as a constraint to most farming systems in broadacre WA wheatbelt... Work from facts, don't guess-measure your soil's p...
GRDC Taxonomy:
Competitive cereal cultivars have higher yield and suppress weed seed set Peter Newman & Abul Hashem, Department of Agriculture and Food.. KEYMESSAGES In a weedy situation at Eradu, Magenta had 36% higher yield and suppressed ryegrass seed set by 65% compared to Wyalkatchem... The research has shown that under weedy situations, UA47 yielded 30% more than Wyalkatchem and halved the ryegrass seed set compared to ryegrass growing in Wyalkatchem plots...
State of Western Australia, 2004 Agribusiness Crop Updates 2004 CONTENTS Page 2003 PULSE INDUSTRY HIGHLIGHTS .................................................................................... 1.. Previous research conducted by the Department of Agriculture, Western Australia established that blackspot of field pea (Mycosphaerella pinodes) is producing windborne ascospores through out the season... Eighty nine different grain legume lines; 22 desi chickpea, nine kabuli chickpea, 10 faba bean, 15 lentil, seven lupin and 26 field pea were evaluated under irrigated conditions at Medina Resea...
