" January 2013 rhizobial inoculants FACTSHEET northern, southern and western regions HArveSTing THe BenefiTS Of inOCuLATing LegumeS inoculating legumes with rhizobia can achieve substantial increases in legume nodulation, grain and biomass yield, nitrogen fixation and post-crop soil nitrate levels... KEy Points The benefits of inoculating legumes with rhizobia (soil bacteria that fix nitrogen) have been recognised in Australian agriculture for more than 100 years... The gains are highest when the legume is grown in nil-rhizobia or low-rhizobia soil...

SOUTHERN REGION BUILDING EMOTIONAL RESILIENCE Emotional resilience is the willingness and capacity to accept that there will be good and bad times ahead, and to understand your reactions to these experiences and have strategies to manage them... KEY POINTS Accept where you are in life and what life is throwing your way... A resilient mindset and dealing with everyday life issues in a calm and balanced manner consists of: accepting yourself for who you are and accept responsibility for looking after yourself; you can do to change your response - it's oureactions that cause the stress; empat...

Optimal timing between applications is dependent upon the herbicides used and the weeds being targeted... The most common double Knock approach is to apply a systemic herbicide (for example Groups A, i or M are frequently used) when conditions are favourable for maximum translocation, and then follow it with a contact herbicide such as the bipyridyls (Group L)... double Knock trial results show consistently high performance when applied to small weeds (prior to tillering for grass weeds and prior to stem elongation for broadleafs) and the applications are applied on time with correct appli...

Although row spacing is a relatively simple thing to change, the effect on the whole farm system can be complex and can influence yield, time of sowing, machinery, herbicide, and seed and fertiliser costs, as well as the types of crops sown... Doubling the row spacing from 18 to 36cm resulted in a two per cent loss in yield in barley and a five per cent loss in wheat... Wider row spacing increases the concentration of nutrients per metre of row if the rate per hectare is maintained...

Crop monitoring from July onwards is key to making effective decisions for controlling diamondback moth... kEy Points Diamondback moth (DBm) can be a serious pest of canola and is found in all grain-growing regions... Bt is broken down by ultraviolet light, so the best results are achieved by dusk application...

Leaf rust can spread rapidly in cool wet conditions devastating soybean crops... Like rusts affecting other crops, the symptoms appear as slightly raised, dull grey/brown pustules on the underside of the leaf (Figure 1)... Downy mildew infection can occur anywhere on the plant and develops a blotchy or uneven spot that does not have a raised area on the underside of the leaf; check to see how far up the plant the infection has spread, that is determine how many green, uninfected leaves the plant has left; and check the stage of maturity of the pods...

Controlling the major fungal diseases of chickpeas in the northern region requires an integrated approach to disease management and prevention... Although burning chickpea stubble reduces inoculum, it does not ensure freedom from AB or botrytis when chickpeas are next grown in that paddock... Poor-quality seed can lead to: seed-borne diseases caused by AB and botrytis; poor establishment and crop performance; reduced plant vigour (which increases susceptibility to soil-borne and foliar pathogens); patchy, uneven plant stands (increases susceptibility to weeds, aphids and viruses); uneven a...

Getting the most profitable results from your farm business requires a careful balance of input costs to produce the optimum yield... Page 2 effect when increased levels of nitrogen are applied to wheat: the first 125kg/ha of fertiliser gives a clear and strongly positive increase in yield, from about 0.5t/ha to around 3.5t/ha (i.e. increasing returns)... Estimating the marginal cost and returns borne from each enterprise's production function will assist with decisions around whether we should apply the next unit of input, such as nitrogen to wheat, canola or peas...

One of the few legal obligations on a farm business is to have an annual tax return completed, so by default, tax returns remain the number one financial record of a farm business... The main problems with tax returns is that they are completed using the Australian Taxation Office (ATO) guidelines and rules, and so do not provide a very good set of accounts needed to more effectively manage the business... If you wish to have the knowledge to do this vital business analysis and answer these questions yourself, or the confidence to ask these questions of your business advisors, the GRDC may...
