DAN00170 - Maintaining profitable farming systems with retained stubble: a review of R,D&E to guide future investment
Effective full stubble retention in the GRDC Southern Region requires integration of multiple components. This project reviewed and evaluated existing research, development and extension (RD&E) material on stubble retention.
CSE181 - Heat disinfestation engineering for grain storage - Possibility of using some of the grain dryers for disinfestation
The use of chemicals to disinfest bulk grain, machinery and storage areas is becoming increasingly unacceptable to the Australian grains industry. The presence of chemical residues and the phase-out of methyl bromide from general use as a fumigant will limit the ability to rapidly disinfest bulk grain and other commodities.
DAV00007 - Reducing Loss of Nitrous Oxide from Grain-Based Production Systems for Greenhouse and Production Benefits - Testing Assumptions
Agricultural emissions of nitrous oxide (N2O) are an important component of Australian emissions. Emissions (from cultivation and nitrogen (N) fertiliser) are currently estimated using default parameters based largely on northern hemisphere data.
DAS293 - Development of cost-effective management strategies for the control of summer growing weeds
Five weeds were selected for long term monitoring to determine the key features of their biology and ecology. They were common heliotrope or potato weed (Heliotropium europaeum), camel or Afghan melon (Citrullus lanatus), prickly paddy melon (Cucumis myriocarpus), caltrop (Tribulus terrestris) and innocent weed (Cenchrus spp).
The aim of this project was to identify deletion lines that lack the SAL gene, which has been implicated as a negative regulator of drought tolerance in Arabidopsis. The project identified seven SAL homeoforms in wheat and classified three of these as SAL1 and four as SAL2.
