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.
The aim of this study was to investigate the impact of paired and single seeding configurations on the timely emergence of crops. While the use of paired row seeding configurations has been popular and well adopted among growers in recent years, there is little independent data to quantify the benefit of paired row seeding configurations on the timely emergence of crops over a range of seeding depths and soil types.
Many people perceive that putting fertilizer with the same nutrient analysis on crops will result in similar yields. This trial was designed to demonstrate the yield differences in using a blended NPK fertiliser as compared to a compound NPK fertiliser. Conducted on red brown sandplain, the trial was located in East Arrino, north of Three Springs.
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.
Potassium (K) is often supplied as topdressed MOP before seeding. However, this may not be the most effective method of application since the K may be pushed into slower-wetting inter-rows by seeding bars. In this trial, K was supplied in differing rates by topdressing MOP immediately after seeding PSPE, after emergence, or in a full NPK compound granule, Vigour, drilled at seeding with or without supplemental MOP to examine effects on germination and emergence and later grain production.
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 report describes results from a trial which was one of a series of trials at a range of locations, investigating the efficacy of seed dressing and fertiliser applied fungicides on the time of onset, rate of development and yield impact of wheat powdery mildew. This trial was conducted in Moora. A major concern for wheat producers is the susceptibility of several popular varieties, the time of onset of disease requiring early intervention in the cropping season and subsequent concerns over requirements for multiple foliar applications.
