To assess the principal causes of erect heads at harvest in April sown wheat crops

Individual objectives specific to the trial were:
- To determine the value of BYDV tolerance in HRZ wheat crops using tolerant and non-tolerant cultivars.
- To assess the connection between erect heads and stem base disease complex e.g. crown rot, eyespot, sharp eyespot in the presence of different stem base fungicide applications.

To examine the phenology, disease resistance and standing power of new wheat germplasm sown on 22nd April versus control varieties.

To develop profitable and sustainable approaches to disease management in high yielding and HRZ regions.

Individual objectives specific to the trial were:
- Monitor the effectiveness of fluxapyroxad (Systiva) for early disease control in wheat.
- To evaluate whether newer germplasm or new fungicide chemistry allows a reduction in the number of fungicide applications whilst increasing profitability (note: reducing the number of fungicides is seen as a key measure for slowing down resistance development in cropping systems).
- Examine whether there is germplasm (varieties tested) that has sufficient early season disease resistance to replace the need for the Timing 1 (T1) spray applied at GS31-32.
- To determine the cost benefit ratio of fungicide application in HRZ regions of different season lengths.

To assess the performance of winter and spring wheat germplasm managed under three different levels of management (22nd April sown).

To assess the value of pre and post GS30 defoliation in winter and spring germplasm grown in HRZ or high yielding regions of different season lengths.

Individual objectives specific to the trial were:
- Assess the dry matter offtake differences resulting from GS22, GS30 & GS32 defoliations and their effect on final harvest dry matter, grain yield and harvest index of spring versus winter wheat.
- Assess whether April sown spring wheat that has been “reset at GS32 (defoliated)” is higher yielding than GS30 and GS22 grazed and ungrazed crops.
- To assess whether the dry matter offtakes of longer season winter wheats at GS22 are more profitable (dry matter offtake and grain yield) than the same winter wheat defoliated at GS30.

To assess the value of higher nutrition input (N, P, K & S) for wheat in the growing season and as an “N bank” for the following season.

Individual objectives specific to the trials were:
- To assess the value of additional nutrients in the growing crop (set up as small plots at the HYC Research sites) and for the following crop (mirror image trial set up in the host farmer’s surrounding paddock).
- To assess the value of adding increased P, K, and S when targeting higher yield potential rather than N alone.

To test the efficacy of a range of experimental (unregistered) foliar fungicides against the above strategy in controlling blackspot in field pea in three major production areas of South Australia.

Farming systems in the low rainfall zone of southern Australia are dominated by cereal production. There is increasing concern about grass weed and soil-borne disease pressure, diminishing soil fertility (particularly nitrogen), and water use efficiency, as a result of continuously cropping cereals. Break crops have a key role to play in addressing these issues, as well as diversifying crop production and economic risk, and maintaining long-term sustainability of the system. However, there remains a lack of information available to growers about choosing the break crop best suited to their situation, as break crop development to date has largely occurred in medium and high rainfall zones. The aim of this research is to identify the best break crop options for different climate, soil type and biotic stress situations within major cropping regions of the southern low rainfall zone.

There has been increasing interest from growers and agronomists in low rainfall farming regions to evaluate alternative break crop options to field peas. Field peas are generally well suited to low rainfall farming systems and have historically been the main pulse option for the upper Eyre Peninsula region. However, record high prices and new varieties with improved agronomic characteristics has renewed interest in alternative pulse options. This is the second consecutive year for this trial and alternative pulse crops to field peas performed poorer in the 2015 season compared to the 2014 season. 2014 saw yields well above the long term averages due to favourable conditions and above average rainfall. Crop means for 2014 have been included for reference.

To analyse the impact of sowing date and variety on the phenology and grain yield of faba beans and lentils in upper Eyre Peninsula.

Pulses are growing in popularity as a result of good prices and rotational benefits such as decreased N input and enhanced grass weed control options. However frost and combinations of water and heat stress at critical growth stages can compromise crop yield. Previous work in pulses has established that the most important time to maintain growth and limit stress is the period around pod set. Sowing date and variety choice are the two main tools to manipulate time of flowering and pod-set, and thus manage the risk of extreme temperatures, water stress and the trade-off between frost and heat risk.

This research aims to identify the safer temperature windows for the critical period for yield for faba bean and lentil in cropping regions of southern Australia. This work follows on from EPFS Summary 2016 p62, EPFS Summary 2017, p146 and EPFS Summary 2018, p62.
