Recently released chickpea varieties are only moderately resistant to this disease fungicide sprays are still required to maximise yield... X Application of Bravo alone did not reduce Ascochyta severity at either assessment as germinating spores had penetrated leaves prior to Bravo application and were no longer vulnerable to the fungicide...

The report proposes the idea that saline water, defined as having an electrical conductivity greater than 1.5 deciSiemens per metre (dS/m) (960 parts per million), has a part to play in filling the void of future losses of surface water... The aim of the report is to investigate if saline water can be successfully used without desalination, and what practices are required to reduce the effects of it on the crops and catchments they are applied to... Drip irrigation systems were by far the most common irrigation system using saline water...

Overarching the basic fundamentals the Federal Government needs to ensure a cohesive national approach to water reform is maintained... We had fallen into the trap that we believed that if we just added water we could make anything grow and for several seasons we had been trying to grow annual rye grass (rye pasture makes up a large percentage of the conventional dairy cows' diet) with little success... On returning from the study we decided to have all of our pivots tested to see if they were operating as we believed they were...

Soil microrganisms also impact on the physical properties of soils including their capacity to hold water... An on-going output will be the coordination of review workshops and reporting processes to ensure that adequate resourcing, integration and consistency measures are being applied across all projects and new opportunities are identified... The major foci of this project are to screen and identify elite diseasesuppressive microbes for cereals and nodulation enhancing beneficial microbes for legumes...

Grain yields can be increased through greater transpiration efficiency (TE), a measure of the efficiency with which water is exchanged for carbon dioxide during photosynthesis... Oil composition can be compromised and lead to a change in fatty acid profiles if the seed is harvested when too moist, the seed has been excessively thrashed, admixture / moisture and disease levels are too high or the temperatures in your silo reach 35 C plus for more than 3 or 4 days in a row... For the reasons above, we need a cropping/pasture rotation..

Graph two is for a heavy clay Black Vertosol from Spring Ridge; results show the plant available water capacity (PAWC) is 272mm... Rooting depth should be determined through perusal of physical and chemical data and the physical observation of roots and water extraction through soil coring and/or electronic monitoring... Simulation of water storage using the >100 year climate record shows that a short fallow from wheat (assuming a dry soil profile at harvest in November of the previous year) results in a 50% chance of at least 110mm (range of 0-300mm) of water being available for an April planting at Spring Ridge and 80mm (range of 0-180mm) at Nyngan (Figure 8)...

People in some areas have very low levels of awareness that salinity is a problem, and report a low level of salinity...
