Description:
This project will deliver new knowledge of the impact of soil type, water availability, and canopy temperature on pulse (chickpea, lentil, faba bean and narrow-leafed lupin) growth and development in current production environments across Australia.
This will be achieved with consistent protocols and standardised measurements on detailed and satellite experimental sites across southern, northern and western regions. It will also include data analysis and simulation.
The project functions alongside independent regional pulse crop development and extension investments and contributes to improved Agricultural Production Systems sIMulator (APSIM) simulations against validated data.
The research will address the following scientific questions:
1. What is the water-limited yield potential of pulses in their traditional environments when grown with best practice agronomy?
2. What is the relation between phenology, water stress, temperature and the critical period for yield formation in pulses?
3. How should the crop design change across sites and seasons having contrasting yield potential for different profit/risk scenarios?
4. Does nitrogen fixation switch off prematurely or reduce under water stress? How does it affect water-limited yield potential?
