• The early maturity of Quilinock and Belara allowed these avrieties to avoid significant crop loss from the first gramozone croptopping treatment.
• Mandelup was affected by the first gramozone treatment but not as much as Tanul and Kalya.
• The competitive yield preformance of Mandelup was also determined.

• A clear advantage in yield was seen with 50cm rows compared to 25cm row spacing.
• It is possible that the response to wide rows at this site would be gretaer if the finish was drier than 2004.
• Consideration needs to be given to ensuring excellent weed control in the wide row system.

• There was significant rain in early April.
• It was very wet at the time of seeding.
• Reduced emergency due to soil crusting and seeding depth.
• There was adequte rain overall but dry at emergence.

• Stubble height would appear to have a statistically significant effect on early lupin plant height.
• This effect, although trending towards a higher lower pod height on those plants, is not statistically significant in this trial.
• This trial had insufficient measurements taken to determine the mechanism that caused the plants growing in the tall residue to grow taller and have a higher first pod, and whether that led to an increase in yield.

• Bambatsi Panic and Rhodes grass have good drought tolerance but maintaining a high plant density has proved difficult.
• Due to low rainfall seasons, more drought tolerant species are required on the site hence planting the saltbush alleys.
• Salinity varies over the site and therefore so does the ground cover, species composition and FOO.
• Roly-poly control can be achieved by spraying with 2,4-D Ester ad Garlon and rolling.

• Overall yields were low in this trial, mainly due to poor establishment and heavy week burden.
• Kaspa was the lowest yielding variety.
• The insect damage was significantly higher in Kaspa than all other varieties.
• Kaspa was released in Victoria and the late maturity of the variety would most probably cuase reduced yields when sown into drying soils in late June.

• With a dry warm summer few grass weeds were present.
• Wet weeds controlled well with sprays.
• Trial germinated well.

The double incorporation of trifluralin method is designed to minimise the number of ryegrass that emerge from the edge of the furrow wall. However, there was no effect of incorporation with rolling harrows, or the snake chian on ryegrass density in the furrow of this trial.

• Germination of half the species at each trial site was above 33 plants/m2.
• Although most of the speices achieved this good germination many of the plants have now died or are looking very water stressed.
• On visual assessment, both Rhodes species and Signal grass have experienced the highest survival rates and are looking the least water stressed.
• The grasses would benefit greatly from a summer rainfall event.

• Under sowing hard seeded Serradella seems to be an economical and sustainable way of establishing pastures the year after a wheat crop, particularly if pods are produced in the farm.
• Sowing depth had no significant effect on germination or plant density, however, it is recommended not to bury too deep pods of Serradella (max 2-3cm) to avoid seedling losses.
• Weed control in the plots was very poor, this could have been a result of no use of wetter with the application of Raptor.

• No significant difference between treatments but interesting trend supporting combined use of protectant fungicides with soil surfactancts, delivered on furrow rather than on fertiliser (this is not a registered pattern of use).
• Warrants further investigation in 2005.

• There has been a drop in surfact pH for all the lime treatments.
• It is anticipated that further works will be carried out at this site.

• The application of lime or dolomite increased soil pH significantly and increased exchangeable Ca and Mg, while the application of gypsum increased soil conductivity levels.
• The nodulation of lupins sown on the gypsum plots was impaired probably because of the high salt levels in the soil.
• Following a drier than average season, lupin yields were lowest where gypsum had been applied in the previous year but benefited from the application of lime or dolomite.

• Mandalup set pods early compared to other than other varieties tested in this demonstration.
• Mandalup yielded significantly higher varieties. If it wasn't for a late rainfall event we would have expected a large difference in yield between Mandalup and the other varieties tested.

• The yields of Mandalup and Balara were the same, however, Tanjil was a significantly lower yielding variety.
• Mandalup looks to be a good option for this environment with its high yield, metribuzin tolerance and early flowering.
• Mandalup did have a higher percentage of protein that Belara, however this was less than Tanjil.

• Monza efficacy on brome grass has not been reduced by the addition of these herbicides and insecticides at the final assessment.
• Some of the treatments were significantly different at the early timing, but the final assessment showed no significant difference.
• Crop phytotoxicity and crop yield were not measured.

The results confirm some suspicions of some observant farmers that a small amount of compaction, or 'firming' can be beneficial to crop yield.

Compaction under the centre of cropping traffic wheelmarks, after deep ripping reduces yield; even in dry seasons.

• Following drier than average seasonal rainfally, yields averaged 1.7t/ha at 31kg N/h and about 2.0t/ha with 73kg N/ha.
• There was no clear K response at either N level.
• Earlier plant testing suggested no response to K application was likely.

• Urea increased wheat grain yield significantly over the nil when banded at sowing.
• There was no significant difference between urea, UAN or MAXamFLO when applied at the same rate of nitrogen and incorporated by sowing, banded or applied at pre-sow, banded and post.

The Drummer ryegrass is a valuable source of early feed and can greatly improve stocking rates if managed in a rotational grazing system.

District input, high input and active input treatments produced the highest yields in both Arrino and Calingiri.

• Wtih three continuous wheat years, all the varieties were very responsive to 120kg N/ha. 
• Increasing seed density is a good management tool for weeds in wheat. At this site, yields increased with increasing seed density without a reduction in grain quality.

Results show that there was a significant increase in grain yield and protein level for brown manure and organic matter treatments.

The trial germinated well with a good start to the season and weeds were well controlled with sprays.

• There was significatn rain in early April.
• There were some dry periods but adequate rainfall overall. Some frosts occurred in July/August.
• Main weed problem was self-sown wheat.

• All fertiliser treatments significantly lifted grain yield from the untreated control with 15cm working depth.
• There was no significant response to applied potassium.

This trial illustrated that there can be some significant benefits to deep ripping post sowing.

Before attempting subsurface lime incorporation it is essentail that the pH profiel be known.

Before attempting subsurface lime incorporation it is essential that the pH of the profile be known. The amelioration treatments were no larger than the effect of the ripping. 

• There was significant rain in early April.
• The paddock was cultivated wet at the time of seeding.
• Seeding was delayed due to seed supply problem.

• Annual disc fallow provided no benefit this season and chemical fallow would be less profitable than whea ton wheat with 600mm row spacing.
• Wilder rows produced a less 'bulky' crop with less biomass/grain weight.

• There was significatn rain in early April.
• Main weed problem was radish.

• Carnamah was the highest yielding variety and returned the greatest gross margin.
• Two recently released varieties, Blanco and Shenton, don't appear to be well suited to this environment.
• There was no rust seen in this trial. If disease was present some of the newer varieties may have performed better than Carnamah and Wyalkatchem.

• The legume rotations increased wheat yields in the following crop by 1t/ha.
• Ripping gave a higher benefit after the legume rotations than non-legume rotations.
• No significant adverse effect on screenings was detected in the higher yielding treatments.

The wide row treatments were closer to achieveing potential yield according to the French-Schultz equation.

• Yield increases were small in the first year of this demonstration.
• Bigger increases may be expected in subsequent years.

• Highly winter active lucerne varieties had better establishment than the winter active or semi dormant varieties.
• Many of the breeder's lines showed better establishment than the commercial cultivars.

• There appeared to be little difference in yield between applying fungicide and nil fungicide. 
• The fenugreek variety Power gave the best yield results as expected as Power is the variety for seed production and Might is a fodder variety.

• An intended comparison between native ryegrass and Safeguard ryegrass became a comparison between what is probably Italian ryegrass and Safeguard ryegrass.
• It was observed that in early November sheep grazed the Italian ryegrass in preference to the Safeguard ryegrass.

Diuron appears to be safe when applied pre-sowing of lupins at label rates, as there was no difference in yield between the Simazine alone and Diuron alone treatments.

 

• There was very little activity from the soil active herbicides due to conditions at the site.
• The idea that higher rates of soil active herbicide might be able to be used with the wide row system was not available to be tested due to the overall lack of response to the herbicide treatments.

• The soil treatments investigated at these sites are considered to be ineffective for broad acre farming.
• Changes to nematode composition and microbial biomass were small and did not result in plant biomass production.
• Inprovements in the effectiveness of the soil treatments may occur when applied as seed dressings.

• Simizine damage early, affected growth.
• Lupin yields averaged 0.77t/ha.
• Protein levels averaged 34.3%.

• Plant densities varied with seed rate, time of planting and variety.
• Quinilock showed the greatest response in protein level to delayed planting time.

• On average the wide row lupins yielded 115kg/ha higher than the narrow lupins.
• Simazine damage was very pronounced in this particular crop. However, damage in the wider rows appeared to be much less than that in the narrow rows.
• The same seeding and fertiliser rates were used for both treatments which made changing the bar over relatively quick.
