The aim of this project (SAGIT S914) was to:

• Provide a genuine legume break crop option for cereal and mixed farmers in the marginal cropping areas of South Australia. Focusing on Western Eyre Peninsula, the Upper North and the Murray lands/Mallee.
• Trial advanced common vetch lines with specific targeted traits in replicated trials in these regions of South Australia for assessment of potential new releases.

• Provide farmers with high yielding alternative vetch varieties that are well adapted to sandy-alkaline soils in low rainfall environments.

The objective of this experiment, conducted at two sites in 2011 was to assess the response of wheat to zinc and/or copper in a standard cropping system.

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.
