This field trial at Gladstone was undertaken to investigate factorial combinations of wheat seed rate and herbicides on the management of annual ryegrass.

The aim of this research was to benchmark yield potential across a range of growing environments in the NGR over two consecutive seasons, and to quantify the effect genotype (G), management (M) and environment (E) had on yield.

This work estimates greenhouse gas (GHG) emissions from grain production systems for different regions of NSW. Data used for analysis was based on DPI gross margins and validated at grower forums in Wagga Wagga and Harden in the southern region. 

 The aim of these experiments is to examine how tillage intensity influences allocation and stabilisation (storage) of newly assimilated C in canola crop-soil and wheat crop-soil systems at Wagga Wagga and Condobolin.
 

The aim of the experiment was to examine the effect of crown rot on yield in 12 bread wheats, one durum wheat and five barley varieties of differing tolerance levels in southern NSW (sNSW).

To assess the effect of early, mid and late sowing times on the phenology, grain yeild and grain protein of several newer wheat varieties grown in southern NSW.

 An international research collaboration with CIMMYT (International Maize and Wheat Improvement Center, Mexico) has developed new wheat germplasm carrying Karnal bunt resistance genes. These will be made available 
to Australian breeders for variety development. As a prerequisite, this study was carried out to determine what penalties could affect yield or its components due to incorporating Karnal bunt resistance. 

In this experiment, we compare three methods of N supply to wheat:
1. surface spread in front of the seeder (early May)
2. mid-row banding at sowing (early May)
3. surface spread at stem elongation (late July).

The difference method was used to evaluated the efficiency of each. 

To explore whether the nitrogen (N) benefits to subsequent cereals from the break crops, and savings from weed control, could offset the loss of income from break crops in the longer term. 

To investigate the influence of sowing date on the phenology and grain yield responses of a core set of 36 wheat genotypes.
 

Under the new NVT Pathology Services Agreement 2019–23, the total number of diseases and crop species being screened in NSW has increased. Eight different crop types, both cereal and broadleaf, are annually screened for a total of 17 different diseases across three climatically and agronomically diverse sites within NSW (NSW DPI research stations based at Grafton, Tamworth and Wagga Wagga).

The objectives were to:

1. reduce nitrous oxide emissions from dryland grains cropping.

2. improve nitrogen use efficiency.

3. validate and develop process-based biogeochemistry models.

4. simulate net greenhouse gas emission under current and projected future climate scenarios. 

In this series of experiments, we have quantified the extent of yield loss displayed in a number of commonly grown winter cereal varieties in southern New South Wales across four years.
 

To assess how rhizosheath formation can improve wheat crop survival in a false break

The aim of this experiment was to develop a better understanding of cool shock as an environmental trigger for LMA expression under controlled environment conditions. 

Please note that the trial was to find out the effect of a cool temperature treatment during grain filling in wheat. 

Variety resistance has little effect on ascospore production by wheat pathogens Zymoseptoria tritici (STB) and Pyrenophra tritici-repentis (YLS)

The study determined whether genetic differences in tolerance can be idenified in field grown wheat exposed to natural heat events at the early reproductive stage of development.

The aim of this experiment was to develop disease response curves indicating potential yield losses for a selection of varieties that represent various resistance categories for YLS.

This experiment examined the effect of yellow leaf spot (YLS) on yield in three wheat varieties of differing resistance in southern NSW.

To evaluate several strategies to achieve high yielding irrigated durum wheat under overhead spray irrigation

Crown rot (CR) caused predominantly by the fungus Fusarium pseudograminearum (Fp), remains a major constraint to winter cereal production in the northern grains region. Cereal varieties differ in their resistance to crown rot, which can have a significant affect on their relative yield in the presence of this disease.

This experiment was one of 11 conducted by NSW DPI in 2016 across central/northern NSW extending into southern Qld; to examine the effects from crown rot on the yield and quality of four barley, three durum and 13 bread wheat varieties.

Varieties (20)

• Four barley varieties: CommanderA, CompassA, La TrobeA and SpartacusA.

• Three durum varieties: JandaroiA and LillaroiA plus the numbered line 190873.

• Thirteen bread wheat varieties: EGA GregoryA, LRPB FlankerA, BeckomA, CoolahA, SunmateA, LRPB LancerA, LRPB ReliantA, LRPB GauntletA, LRPB SpitfireA, MitchA, SuntopA and SunguardA; (listed in order of increasing resistance to crown rot) plus one numbered line LPB12-0494
