Role of medics as break crop in annual mixed farming system and impact on following crop. Opportunities for improving crop production using pastures.
Outlines alternatives to owning livestock for cropping businesses. case studies include profit sharing, share farming, livestock leasing and ajistment.
Trade off between medic pasture growth and yield of a following cereal crop, with different medic pasture termination timings.
Trade off between medic pasture growth and yield of a following cereal crop, with different medic pasture termination timings.
Very early sowing of winter wheat for grazing and yield potential.
Growing season lengths did not necessarily influence variety feed value; both early and late maturing varieties performed equally well in the 2012 dry season. Hindmarsh barley was one of the best varieties: it consistently produced valuable feed at both sites and had highest grain yield at Birchip (ungrazed 3.1t/ha).
Simulated grazing (mowing) reduced canola grain yield by 17%.
Assessment of barley grass weed management with a two year medic pasture break. Impact on medic DM production, N, disease.
Aim of the farm demonstration is to increase production and sustainability and reduce costs by identifying production zones across a property and managing these zones differently.
Improved lines of medics with powdery mildew resistance and SU tolerance. Improved pasture production.
Trying to improve performance of medic pastures in establishment (inoculation, sown vs regen) and management phases (+/- grazing). Improving pastures and subsequent crops.
Assessing perennial shrubs for grazing on upper EP in the Enrich program. Improving feedbase options.
Assessing multipurpose 'break crops' (cereals, broadleaves, forage peas, vetch) on upper EP.Opportunities for improving pasture and subsequent crops.
Identifying alternative forage legumes for EP environment such as lucerne, cullen, tedera and sulla.
The domination of cereals is increasing the need for non-cereal options to provide profitable rotational crops, disease breaks and weed control opportunities to sustain cereal production.
Sulla establishment and production demonstration at Minnipa Ag Centre. Rhizoctonia levels rose unexpectedly under sulla. Non G&G product.
Wheat yields after a two year break were a significant step up from wheat crops following a one year break, which were in turn, much better than the continuous wheat. Large break crop benefits of 0.5-1.25 t/ha were achieved following a two year non-cereal break
Simulation study aimed at better understanding the mixed farming systems that include short-term (3-year) phases of lucerne.
Despite their unrivalled value in livestock systems, certain temperate, pasture, legume species and varieties may contain phytoestrogens which can lower flock/herd fertility.
Opportunities to improve pasture production through capability development in soil nutrition. Describes work looking at the reduced nodulation in sub clover due to increased soil acidity and lack of key rhizobial nutrition.
Highlights opportunities for improved nitrogen mineralisation for cropping through incorporation of livestock. Identifies and quantifies the role of sheep grazing of stubbles in the breakdown of stubble and nitrogen mineralisation.
Highlights opportunities to improve pasture utilisation and increase stocking rates. Summarises research on rotational grazing and paddock subdivision.
Highlights opportunities to improve productivity through capability development in pasture management. Includes a survey of pasture establishment practices across the mixed farming region of southern NSW.
The current practice of sowing well adapted varieites at their optimum time is well suited to SA. However there may be opportunities to utlilise longer season varieties in some environments or where large seesing program prevent sowing all varieites in their optimum time is well suited to South Australia.
Well adapted winter wheats and longer growing season spring wheats have a role to play when sowing very early.
Overview of the impacts of managing Sulla and herbide impacts
This paper explores the viability of the forage legume Sulla as a viable two-year break crop in the Southern region
Assessing the impact of nutrition, herbicides, adjuvants and rhizobial inoculants on N fixation by medics.
A collated 11 year history of a paddock comparison between no till and various grazing and stubble burning regimes.
Market research condcuted in 2010 to understand the motivations, attitudes and issues for growers and advisors using fodder (legume) break crops
Opportunities for hard seeded legume pastures.

Compare the yields of crops grown under four different farming systems common to the Southern Mallee. Standard and Fuel Burners outyielded No Till, followed by Reduced Till, followed by Hungry Sheep.
