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.
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.
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.
This trial looked at Serenade Prime as product to increase marketable potatoes and uniformity in tuber size through two applications during the growing season. Serenade Prime did not result in an increase of total yield but recorded an improved number of ‘marketable’ potatoes from the treatment through the reduction of smaller tubers and a higher percentage of medium sized, premium tubers. The trial was conducted near Dandaragan on sandy duplex soil.
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.
These projects aimed to address the questions "Is this paddock performing up to potential, and if not, why not?" by persuading interested growers to apply test strips of various management practices (windrows, fertilisers, lime, wetting agents, cultivation) across their paddocks and soil types. The presence or absence of visual responses to these strips should stimulate further plant, tissue and soil sampling for analyses and the total results would be interpreted by experts. Lack of participation in the diagnostic projects, considerable value was gained from opportunistic sampling and diagnostics associated with observed growth variations in paddocks from crops across windrows and from better growth patches.
This trial was conducted in Dandaragan to determining the value in $/ha for each weed control component in the canola crop within specific herbicide technology systems and then developing a software model to calculate the individual and cumulative value to growers of each of these elements for weed control in a “Integrated Weed Control Package”. The site experienced low starting rainfall with staggered plant emergence and then with further rainfall plot populations were within 75 to 85% of targeted plants/m2. All pests and diseases were controlled to an acceptably high level.
This trial was conducted by Southern Dirt and aimed to improve the adoption of liming practices in the medium to high rainfall zone of Western Australia by demonstrating the economic and environmental benefits of lime application and incorporation. The trial site was located 12km north of Kojonup and was chosen for its combination of targeted soil type (forest gravel) and pH range (4.5 – 4.8 CaCl2) up to a depth of 60cm.
This trial was one of a series (other trials at Eradu, Cunderdin, Esperance) investigating the value of at-seeding fungicides in terms of replacing early foliar fungicides or supplementing later foliar applications. The trial was located in Dandaragan. The results showed that fungicide seed treatment or in-furrow did not affect germination or emergence.
