Callum keeps the wheels turning on seeding innovation.. Grower Callum Wesley, of Southern Cross, is developing and trialling a new seeding system for lower-rainfall areas - called the Wesley Wheel - that harvests moisture in inter-row furrows... At Southern Cross, Callum says it was a challenging season, where daily rain events in June, July and August did not exceed 5.4mm - reducing water-harvesting potential...

" Goondiwindi GRDC Grains Research Update Day 1 - Tuesday 4 th March Time Topic Speaker (s) 10:00 AM James Clark (Chair Northern Welcome Panel GRDC) 10:10 AM General plenary (Supported by North West Local Land Services) 10:10 AM 10:40 AM.. Overall, both models are acceptable for modelling soil evaporation over a range of soils and seasons provided accurate soil physical properties and starting water states are known... Overall, populations increased five times compared to before planting the summer crops, but remained below 250/kg soil (Figure 4)...

Influence of fungicide rate (mean of fungicide products - four site mean) Stem rust control assessed over the four trial sites revealed that using high rates was essential for the control of the disease, even if the fungicide had been applied prophylactically (before infection was visible in the crop)... Influence of cultivar resistance and fungicide application (Prosaro ) on yield and stem rust severity measured on the flag sheath 18 days after fungicide application at early dough (GS82) and assessed at mid dough - physiological maturity (GS85-90) - Bairnsdale, Gippsland, Victoria, 2010... The yield potential for the crop with no nitrogen applied is estimated at GS30 from the results of numerous of trials conducted in that region where NDVI at GS30 is divided by the number of growing degree days (GDD) greater than 0 C since planting, referred to as the INSEY units (in season estimate of yield)...

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...

Growers urged to count the yield cost of wide rows.. Winter cereal growers in the northern region are being urged to carefully assess the yield cost of their row spacing decisions... Grains Research and Development Corporation (GRDC) supported trials by NSW DPI researchers at the Tamworth Agricultural Institute and the Condobolin Agricultural Research & Advisory Station in 2009 and 2010 found that yield loss from 30 cm to 40 cm row spacings averaged approximately 0.3 tonnes/hectare but varied from less than 0.2 up to 0.8 t/ha...

Count the cost of wide rows.. The widespread adoption of minimum and zero tillage farming systems in the north has been a driving force behind the practice of widening row spacings which enable some growers to better handle stubble loads, reduce machinery and planting costs, and maximise soil water infiltration and storage... Although row spacing is relatively simple to change, the effect on the whole farm system can be complex and can influence grain yield, timeliness of sowing, machinery choice, residual herbicide choice, seed and fertiliser costs, weed management, development of herbicide resistance, and the configuration of other crops sown within the farming system...

Ben Cripps of Ogilvie is widening his canola row spacings to help reduce risks and cut costs - a strategy that is being further examined with GRDC funding... The Cripps family at Ogilvie is part of a new movement in the northern agricultural region pushing canola row spacings wider to reduce risks and cut costs... Ben says 2014 trials on their property found that using low seeding rates of 1.5 kilograms/ha at 60cm spacing produced marginally higher yields - about 80kg/ha - than using seeding rates of 3kg/ha at 30cm spacings...
