• To investigate posture cropping - involving seeding an annual winter active species (peas) into an existing summer-active perennial pasture stand (kikuyu).

To discuss nitrogen inputs from pasture and patterns of release for crops.

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.

The aims of these experiments were to determine:

• the potential effect of natural enemies on insect pests

• any long-term effects from insecticide seed treatments on natural enemies

• any differences in natural enemies and pest distribution.
 

This app was developed for weather-based irrigation scheduling using a crop coefficient (Kc) estimated from satellite observations and reference crop evapotranspiration (ETo) estimated from scientific information for landowners (SILO) grids (Jeffery et al. 2001).

 To investigate whether competitiveness can be increased in chickpea and faba bean to reduce sowthistle biomass and seed production, and how this affects crop yield.
 

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).

This project conducted a preliminary investigation to determine whether an objective remote sensing method could be a feasible alternative to hand sampling, and to guide further research.

The aim of this experiment was to understand canola variety heat stress responses and their capacity to adapt to warmer future climates.

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.

This study aimed to compare the efficacy of three different foliar fungicides in managing sclerotinia stem rot in canola.

To compare growth, development and yield of current commercial faba bean varieties and advanced breeding lines sown on three dates on a red brown–earth at Wagga Wagga in southern NSW.

To compare the growth, development and yield of current commercial faba bean varieties and promising advanced breeding lines at three sowing dates on a hard-setting, acidic, red brown soil at Wagga Wagga.

To compare growth, development and yield of current commercial faba bean varieties and advancing breeding lines at three times of sowing (TOS) at Wagga Wagga.

To identify frost damage in canola and assess symptoms and risk

 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. 

This experiment evaluated the two new imidazolinone (IMI) herbicide-tolerant lentil varieties PBA Herald XT and PBA Hurricane XT alongside other commercial varieties and breeding lines for adaptation and production in southern NSW

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 establish agronomic guidelines for lentil time of sowing (TOS) and seeding rate for current commercial lentil varieties and advanced breeding lines at Wagga Wagga. 

To compare growth, development and yield of current commercial lupin varieties and promising advanced breeding lines sown on three dates on a red–brown earth at Wagga Wagga in southern NSW. This information will be used to confirm and update current agronomic
recommendations for lupin in this region.

This experiment aimed to evaluate agronomic management options that enhance the yield potential on this specific soil type.

This experiment compared different rhizobia inoculant formulations on nodulation, growth and yield of field pea, lupin, faba bean, lentil and chickpea under varying rain-fed and soil moisture conditions on an acidic, red-brown earth at Wagga Wagga in the south-eastern cropping zone of southern NSW

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. 

This experiment examined the phenology of 31 commercial varieties and newly released lines sown on two sowing dates at Wagga Wagga, NSW in 2019.

An experiment at Wagga Wagga in 2020 examined the phenology of 34 commercial and newly released varieties sown on two dates.

This paper reports on the priority diseases identified in the 2020 crop surveys and highlights implications for grains producers in 2021.

The aim of this work is to increase the sources of multi-disease resistant germplasm available for barley variety improvement in Australia. This is being achieved by screening and identifying possible sources of resistance to barley scald and other diseases from the centres of origin of barley cultivation. 

This experiment, which was part of a larger project based at Tamworth (BLG106), was conducted to determine the effect on chickpea and lentil crop development and grain yield from varying amounts of cereal surface residue (mimicking stubble load) and the resulting lower temperatures.
