The purpose of the canola NVT trials at Dandaragan is to provide growers and their advisors with independent information on the performance of newly released varieties of canola relative to the current commercial varieties grown in the area. The intention is to have two years of data available on the NVT website at the time each new variety is made available for commercial production. The 2016 trial was located in Dandaragan on brown grey sand to yellow brown sand at depth.
Managing wheat nutrient inputs for both yield and protein is an ongoing challenge with seasonal rainfall variability, management practices and other factors continually increasing yield potential. Traditional approaches to N management may be leaving crops short – evidenced by disappointing grain protein levels in recent seasons. Growers may be forgoing profit by playing the season late and not addressing crop demand early when yield potential is critically set.
Summit Fertilizers compared a number of strategies to increase nitrogen application rates to match site conditions for yield potential. Applying various N rates at multiple combinations of timing splits provides a range of contrasts to assess impact on yield, grain quality and profitability.
Effective nodulation of legumes is important to maximise the amount of nitrogen fixed by the legume; however, lupins are not usually treated with inoculant due to the presence of native inoculant in the soil. It is unclear if this native inoculant is as effective as newer types of inoculant, and the objective of this project is to evaluate TagTeam on the nodulation and grain yield of lupin and chickpea on a sandplain soil. At this trial there was no yield benefit in applying an inoculant on lupin seed. Although there was a noticeable improvement in crop establishment and nodulation when doing so (from a 2.9 rating to a 3.9 nodulation rating), it did not translate to yield. It is possible that this is because the frequency of lupins grown in this environment has been high, and therefore enough numbers of rhizobia are present in the soil to achieve suitable nodulation. The dry finish to the season may have also influenced the final yield.
The aim of the National Variety Trial (NVT) program is to generate independent information for growers and industry about newly released varieties of winter field crops relative to the current commercial varieties grown in the area. The data generated can be compared by year/s, location and variety, providing an important decision support tool for growers when assessing if they are growing the right varieties for their farm business. This trial was sown onto a high yielding, burnt barley stubble on the 24th May.
The soil type was a high quality dark Dandaragan sand/loam. Unlike many areas of the state in 2019 this site had reasonable subsoil moisture from some earlier localised rain so germinated and grew exceptionally well. The late start to the season and dry spring tended to suit the quicker varieties, however good yields were returned by all varieties in the trial.
Legumes can provide value to the crop rotation through the fixation of nitrogen, and there is the need to evaluate a wider range of legumes that could be grown in WA. Nine demonstration sites were established across the wheatbelt region as part of a GRDC project led by Liebe Group. In 2018, demonstration strips of field pea, lupin, lentil, and chickpea were grown and then followed by Scepter wheat in the 2019 season.
The West Midlands Group demonstration site was located at ‘Kayanaba’, 1 km east of Dandaragan on a clay loam soil type. The site was sown and harvested by the grower and managed similar to the remaining area of the paddock. The Gross Margin was calculated for 2018 by Farmanco as part of the overall project, while Gross Margin was calculated in 2019 based on grower supplied data, and including machinery costs at contract rates.
Matching pasture production and livestock requirements can dramatically improve animal production while reducing the cost of supplementary feeding. The aim of this trial was to evaluate a range of pasture mixes that have the potential to fill niche pasture production windows in the West Midlands region. This pasture demonstration site was located at the 2019 Spring Field Day site near Dandaragan on a sandy loam soil type. The site was established on the 5th May using a plot seeder to dry seed 12 pasture mixes, with a volunteer pasture adjacent to the site as comparison. Up to three pasture cuts were taken from each plot during the season to assess pasture production. The site was mowed in August to simulate grazing, and NKS21 fertiliser was broadcast to each treatment.
This trial aimed to evaluate early foliar disease suppression of soil applied fungicides, compare early soil disease control to a foliar only strategy, compare efficacy of different foliar fungicides on yield at a ~Z31 and Z39 applications as well as comparative of seed treatments.
This project investigates the use of double break crops to increase the yield of subsequent wheat crops in the Kwinana East and West port zones of the WA grain growing region through the use of field experimentation.
The wheat varieties bred for traditional wheatbelt with the low and medium rainfall may limit yield potential when grown in the high rainfall area. Lengthening the construction period duration (CPD) of the spike growth may increase the sink size and therefore potential yield. The aim of this study was to evaluate the relationships between yield, flowering time and the duration of spike growth period and to investigate whether yield can be improved by lengthening CPD.
Omission trials are a good visual way of highlighting the importance of each nutrient. In this trial we looked at each macronutrient and its importance to canola. Soil tests run through NUlogic suggested the potential for deficiencies in nitrogen (N), sulphur (S) and possibly potassium (K). This trial was conducted in Dandaragan on sandy loam soil. The site was very responsive to nitrogen (N) fertiliser.
