Field peas trials

To investigate the reasons for these differences in WUE by continuing with trials established at 4 sites in 2008 on different soil types and rainfall zones in selected grower paddocks.

To assess the performance of wheat following either peas, wheat or barley.

The objective of this trial is to demonstrate that growing canola (with effective weed control options) followed by a high value legume (with higher economic value) can lead to an effective and profitable double break crop sequence. The contribution of an early sowing date versus a traditional sowing date to increase the profitability of these crops will also be evaluated.

This project will determine the economic value of growing canola followed by a high value legume, and the impact of this rotation on the grain yield and profitability of a cereal crop in the first year following the double break crop sequence.

To measure N20 emitted by vetch, field peas and wheat stubble over summer and to determine whether
top-dressed inhibitor-treated and slow release urea products influence N2O emissions.

To investigate the idea of Pasture Cropping (PC), which involves seeding a crop into an existing summer-active pasture stand without killing the pasture.

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

To investigate establishment, crop phenology, days to flowering, flowering duration, and grain yield responses of commercially available pulse and legume varieties.

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. 

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.

To answer the question - continuous cropping - is it sustainable?

To investigate the management, sustainability and profitability of a range of farming systems. 

To test the hypothesis that over time in controlled traffic farming systems the repeated uneven spreading of header residue back over the tram track width would result in changed soil conditions that would ultimately lead to different “management zones” along the tram track.

To identify any possible impacts on crop growth in controlled traffic systems where the header residue maybe inconsistently spread back across the tram track width over a number of seasons.

To measure N20 emitted by vetch, field peas and wheat stubble over summer and to determine whether top-dressed inhibitor-treated and slow release urea products influence N2O emissions.

To report on the use of pulses now and in the future.

The objectives were to:
1. manage subsoil acidity through innovative amelioration methods that will increase productivity, profitability and sustainability
2. study soil processes, such as the changes of soil chemical, physical and biological properties under vigorous soil amelioration techniques, over the longer term.

To report on the role and management of high density legume break crops in dryland dropping rotations.

To address the problem of subsoil acidification, a long-term field experiment was established in 2016. The objectives were to:
• manage subsurface soil acidity through innovative amelioration methods that will increase productivity, profitability and sustainability
• study soil processes, such as changes in soil chemical, physical and biological properties over the long term.
