Overview

Professor Bhagirath Chauhan joined the Queensland Alliance for Agriculture and Food Innovation (QAAFI) at The University of Queensland in 2014. He now has a joint appointment with QAAFI and SAFS at UQ. He leads research on weed biology and weed management in different crops, including wheat, maize, sorghum, mungbean, soybean, chickpea, rice, and cotton. He has studied the seed ecology of >100 weed species and he has a vast experience in developing integrated weed management options based on agronomic approaches (row spacing, seeding rates, weed-competitive cultivars, etc.). Prof Chauhan has more than 20 years of research experience in conducting trials on the improved agronomy of new production systems and integrated weed management options in Australia and >10 Asian countries. Before joining UQ, Prof Chauhan worked at the International Rice Research Institute (IRRI) in the Philippines for seven years. He has a strong collaboration in several countries, including USA, Sri Lanka, India, Nepal, Iran, Pakistan, Nigeria and China. His research interests include weed ecology and biology, herbicide use, management of herbicide-resistant weeds, non-chemical weed management options, integrated weed management systems using agronomic and varietal components, nanoherbicides, tillage systems, and conservation agriculture systems. He is a Speciality Chief Editor with Frontiers in Agronomy and an Associate Editor of Weed Science (Weed Science Society of America). He has published over 350 articles in peer reviewed journals and several books and book chapters. He is an Honorary Member of Weed Science Society of America (WSSA) and a life member of International Weed Science Society (IWSS), Asia Pacific Weed Science Society (APWSS), and Indian Society of Weed Science (ISWS).

Available Projects

  • Projects, based in Brisbane, available for Hons, Masters and PhD students. These projects will evaluate the nutritional profile of emerging (useful) plant species.

  • Sesame is an emerging crop in Australia. There are several ethno-botanical and mideicinal uses of this nutritionally rice oilseed crop. However, knowledge on its agronomy is very limited in Austrain conditions. There are projects available (Hons, MS and PhD) to optimise its planting depth, planting density and row spacing. Being a slow growing crop, it is prone to heavy weed infestation. Herbicide options are very limited and therefore, there is a need to screen different pre- and post-emergence herbicides to manage weeds in sesame. Effective (on weeds) and safe (to the crop) herbicides will be integrated with cultural approaches to develop integrated weed management programs.

  • Love grasses (African, stink and hairy flower) are becoming problematic weeds in pastures, grain crops and along roadsides. Limited information is available on their biology and management in Queensland. This project, based at Gatton, is available for Hons and Masters (course work and research work) students. Discuss with Bhagirath Chauhan (b.chauhan@uq.edu.au; 0427923272) for more detail.

Possible Research Projects

Note for students: The possible research projects listed on this page may not be comprehensive or up to date. Always feel free to contact the staff for more information, and also with your own research ideas.

  • Projects, based in Brisbane, available for Hons, Masters and PhD students. These projects will evaluate the nutritional profile of emerging (useful) plant species.

  • Sesame is an emerging crop in Australia. There are several ethno-botanical and mideicinal uses of this nutritionally rice oilseed crop. However, knowledge on its agronomy is very limited in Austrain conditions. There are projects available (Hons, MS and PhD) to optimise its planting depth, planting density and row spacing. Being a slow growing crop, it is prone to heavy weed infestation. Herbicide options are very limited and therefore, there is a need to screen different pre- and post-emergence herbicides to manage weeds in sesame. Effective (on weeds) and safe (to the crop) herbicides will be integrated with cultural approaches to develop integrated weed management programs.

  • Love grasses (African, stink and hairy flower) are becoming problematic weeds in pastures, grain crops and along roadsides. Limited information is available on their biology and management in Queensland. This project, based at Gatton, is available for Hons and Masters (course work and research work) students. Discuss with Bhagirath Chauhan (b.chauhan@uq.edu.au; 0427923272) for more detail.

  • Giant rat's tail grasses (Sporobolus species) are becoming problematic weeds in pastures, grain crops and along roadsides. Limited information is available on their biology and management in Queensland. This project, based at Gatton, is available for Hons and Masters (course work and research work) students. Discuss with Bhagirath Chauhan (b.chauhan@uq.edu.au; 0427923272) for more detail.

  • Weeds are known to have a high level of genetic diversity. Studying the genetic diversity and population structure of weed biotypes would be helpful in understanding the evolution and adaptation of weed biotypes, thereby aiding in formulating an effective weed management program. In collaboration with molecular biologists, this project will study genetic diversity in key weed species (e.g., Feathertop Rhodes grass, Fleabane, Common sowthistle, etc.). A previous example from this lab is on barnyard grass: Chauhan et al. 2022, Genetic diversity and population structure analysis to study the evolution of herbicide resistance in Echinochloa colona ecotypes in Australia (https://link.springer.com/article/10.1007/s11738-022-03366-x). These projects may involve travel (funded) to collect weed seeds and they will be based at Gatton (growing plants) and St Lucia (molecular studies). Scholars who are committed to write journal publications will be accepted.
