saline soil

Catalogue: GRDC Final Reports
The rationale for the project was an increasing awareness that subsoil salinity is an underlying constraint to cereal production in many regions of southern Australia... Growers will have access to salt-tolerant cultivars of wheat and barley that will enable them to make more informed choices to improve the productivity and reliability of crop yields in salt-affected land... The three general mechanisms of salt tolerance in wheat and barley are the exclusion of salt, the tolerance of high internal salt concentrations in leaves ("tissue tolerance") and the tolerance of high external salt concentrations in the soil ("osmotic stress tolerance")...

Larvae are often present in lucerne but most contract a viral disease that normally controls helicoverpa numbers... Spotted alfalfa aphids are potentially the most damaging of the aphids while blue-green aphids and, occasionally, pea aphids usually decrease production without causing serious plant losses... A common insect pest in lucerne in many districts, adults cause only minor leaf damage but their larvae, which are creamy white in colour and roughly resemble maggots, feed on taproots and secondary roots of lucerne plants...

A new research paper presented at the Grains Research and Development Corporation (GRDC) Updates provides a comprehensive outline of the tools available to cost-effectively measure soil water leading into summer crop planting... "Devices include in-situ devices that have relatively small zones of measurement and rely on good soil/sensor contact to measure soil water are at a disadvantage in shrink/swell soils where soil movement and cracking are typical... "In comparison, the use of a portable EMI device to measure bulk electrical conductivity and calculate soil water has a number of advantages."..

A trial evaluated the production of wheat, barley and durum on a saline and non-saline site at Ballidu, Western Australia (WA), in 2009... Given this (relationship between salinity and B tolerance), we believe that it will probably be easier to improve grain yield on salt land by inserting a small number of genes for B tolerance into barley, than by inserting an unknown but presumably larger number of genes for salt tolerance into wheat.".. The proposal aims to develop and validate quantitative trait loci (QTLs) for waterlogging, salinity and element tolerance of wheat grown in India and Australia...
