2017 Seasonal effects of strategic stubble treatments on Canola in CW NSW Background CWFS conducted trials across the central western district that: investigated the impact that different stubble treatments (burning, cultivation, harrowed or standing stubble) imposed just prior to sowing have on the growth and yield of winter crops, measured using large plotsevaluate any grower...
2016 Cereal response to stubble treatments in Central Western NSW Key Points from 2016 Burning or cultivating 2015 stubbles tended to produce higher yields, however this was only significant at UngarieHigh rainfall and a soft finish removed the benefit of stored soil moisture that stubble retained systems may have providedNitrogen was the limiting factor for...
Stubble efficiency – Stubble GrazingCondobolin 2015 Key points Treatment 1, Nil grazed, moderate stubble yielded the highest, (2.18 t/ha).No significant difference in Total Plant Available Water, the majority of stored water was below the 50 cm depth.There was a significant difference between the eight treatments when comparing available soil nitrogen.There was a significant difference in...
Stubble efficiency – Stubble GrazingCondobolin 2015 Key points No-till treatments, for all rotations, were slightly higher-yielding than the conventional tillage treatments for wheat. The yield of peas, in rotation 2, was very low in this trial as a result of the season and Sakura® damage.Rotations including a fallow, such as the WFW treatment, had lower...
Cultural control strategies: the impact of stubble management on invertebrate pests in dryland cropping systems 2015 trial Key points Pest density was very low throughout the course of the trial and there was no obvious impact of stubble management practices on ground-dwelling pest numbers.High numbers of beneficials (mostly ants and spiders) were active in the...
2015 Seasonal effects of strategic stubble treatments on nitrogen response in wheat in CWFS districts The focus of recent research is concentrating on maintaining profitable retained stubble systems rather than investigating the agronomic and economic benefits of stubble retention. Background CWFS are conducting trials at its regional sites that: investigate the impact of different stubble...
The Merriwagga tillage and rotation trial was established in 1999 aimed at comparing no-till farming techniques against conventional farming methods over 5 different cropping rotations. Access the report

Key points Long fallows and green manure crops are valuable management tools that increase soil moisture and nutrition for the following crop.Controlling weeds 100% of the time in fallows preserves maximum soil moisture. Spraying weeds late in this trial equated to lost income of $85.56/ha as a result of lower grain yield and quality.Vetch as...
