Funding overview

Professor Siddique has attracted numerous ARC, ACIAR, AusAID, Australian Government, CGIAR and industry-funded (GRDC, MLA, RIRDC, GRC, COGGO) projects, and has collaborated nationally and internationally on research in cereals, oilseeds, grain and pasture legume crop physiology and agronomy.


Professor Siddique’s major contribution to dryland agriculture has been crop yield improvements in grain legumes and wheat in the fields of crop physiology, production agronomy, germplasm development and breeding. Research in these disciplines is rarely conducted in parallel and, therefore, rarely integrated. Professor Siddique maintains contact with end-users and always involves industry and farmer groups in the first steps of developing his research projects. His research is relevant to the farming community and aims to solve real problems through meticulous scientific research methodology and collaboration. His research is directly relevant to international researchers, producers and communities as illustrated by his numerous international linkages.

Wheat yield improvement in Mediterranean-type environments

Professor Siddique led a team of physiologists, breeders and agronomists in WA to understand the constraints of dryland cropping in the Mediterranean environments of southern Australia and to explore opportunities for yield improvements in wheat.

Professor Siddique's research highlights on wheat include:

  • Contributed key papers on the development pattern of old and modern wheats to the ‘Flower model’ which is used extensively to predict flowering time in Australian wheat varieties. His research showed that the rate of spikelet initiation is faster than that of leaf initiation and modern wheats have faster rates of spikelet initiation than old cultivars.
  • Identified ear:stem ratio as an index of competitive strength of the ear, which is highly correlated with harvest index (HI), grains per ear and grain yield, and a better indicator of yield potential than HI because it is determined early in the lifecycle and, unlike HI, is not affected by environmental stresses after anthesis.
  • Identified a strong negative relationship between pre-anthesis water use and grain yield in WA, which was related to the early maturity of modern wheats. Water use efficiency (WUE) for biomass production did not improve with selection for yield but, as a result of earlier anthesis and improved HI, WUE for grain production increased in modern wheats.
  • Identified that modern wheats produce less dry matter and lower root:shoot ratios than old wheats which probably relates to earlier sink development, fewer tillers and fewer nodal roots associated with tillers. Professor Siddique and his students recently showed that grain yield in wheat under terminal drought depends on post-anthesis water use regulated by stomatal conductance and root capability to extract available water from the soil. Elevated CO2 ameliorated the negative effects of terminal drought on biomass and grain yield, due to increased rates of leaf net photosynthesis and increased tiller numbers, leaf area, biomass and grain numbers. The increased grain number per year resulted from increased survival of competent florets at anthesis.
  • More recently, Professor Siddique and his team have focused on developing rapid root phenotyping techniques for large amounts of germplasm in crop plants such as lupins, chickpea and wheat.

Grain legume adaptation, improvement and production technology

Professor Siddique’s pioneering research on chickpea adaptation to dryland environments has contributed enormously to the Australian chickpea industry (currently valued at >$500 million pa). His leading role in breeding, selection and development of high-yielding superior legume cultivars resulted in the commercial release of 13 grain legume cultivars in Australia.

Professor Siddique's research highlights on grain legumes include:

  • Identified a clear species × environment interaction on the growth and yield of commercially-grown and potential new grain legume species in the Mediterranean environments of south-western Australia.
  • Identified a positive correlation between post-flowering water use and grain yield in 12 cool-season grain legumes across a range of environments in WA. For the first time, Professor Siddique and colleagues developed benchmark values of transpiration efficiency to assess yield potential in cool-season grain legume crops in dryland environments.
  • Identified germplasm for chilling tolerance in chickpea and established a novel breeding technique based on pollen selection to commercially release two chickpea varieties with improved chilling tolerance and yield.
  • Together with Australian and international collaborators, Professor Siddique recently published a perspective paper on grain legumes in Nature Plants and special issue of Journal of Experimental Botany.

Dryland agricultural ecosystems and conservation agriculture

Sustainable food production and security are a major concern worldwide. Australian agriculture faces challenges such as frequent droughts, high temperatures, nutrient-poor soils and dryland salinity. The agroecosystem of the Loess Plateau in China is typical of a developing region and rainfed farming is the most widespread land-use practice. Over-cultivation of these marginal lands has led to severe soil erosion. The development of integrated cropping/animal production and agrosystems management is a priority for China and Australia. Professor Siddique and his team have been working with Lanzhou University and ICARDA since 2006 on various aspects of agricultural ecosystem management in dry areas; more than 60 joint papers have been published, and technologies have been developed and tested including plastic mulching, ridge–furrow planting methods, water use and WUE, lucerne production systems and fertiliser management. Recently, this information has been compiled in a book on ‘Innovations in dryland agriculture′.

Conservation agriculture (CA) is an important technology for sustainable production in dryland systems. CA has been tested and validated in various regions worldwide, but CA components are complex and location-specific, including crop residue management, cultivar selection and crop choice for rotation, strategies for nutrient management, tactics for weed management, disease and pest management, and soil water management practices. Professor Siddique was a key leader of the Conservation Agriculture in Northern Iraq and Australia project (funded by ACIAR and AusAID) in collaboration with ICARDA. As part of this project, MSc students and PhD students from Iraq and Australia were trained on various aspects of CA at UWA, and several papers, a special issue of Field Crops Research, a book by Springer and several reviews have been published.

The gap between average and potential crop yields varies from 0.5 to >5 t ha–1  depending on the agro ecological region and available technologies—leaving considerable scope for future yield improvement.
