Crop Physiology and Metabolism

CSSA offers specialized Divisions of Interest, giving you the opportunity to develop focused peer networks and information resources. Via the divisions, members present papers at the Annual Meetings and participate in the business meetings. The divisions may also host listservs, web pages and newsletters. As a division member, you can also guide the division direction by participating in elections and serving through leadership opportunities. As a CSSA member, you may belong to as many CSSA Divisions of Interest as you would like.

Division C-2 Picture of Farm


Crop physiology is the investigation of the plant processes driving growth, development, and economic production by crop plants. Crop physiologists use basic research (driven by a scientist's curiosity) and applied research (designed to solve practical problems)to understand how crop plants function. Their focus is on whole plants and plant communities more so than individual plant organs or cells because most of the processes that control yield operate at the whole plant level with an intimate interaction with the environment.

Consequently, most crop physiology research is conducted in the field or in near-field environments of greenhouses or growth chambers. Crop physiologists examine primary production including photosynthesis, respiration, nitrogen fixation and nutrient uptake. How primary products or assimilates are utilized for growth and yield attainment are also evaluated. The interaction of biotic (pests, diseases, predators) and abiotic (water deprivation, temperature extremes, flooding, atmospheric pollutants) stresses with crops is of major importance.

C02 Graduate Students Awards 

Annually, Div. C02 sponsors one Oral and one Poster Graduate Student Competition as Div. C02 Topical Sessions. Presentations are meant to encourage creativity and participation of the students in the field of crop physiology and metabolism. The top 3 students for both oral and poster competitions are recognized with a cash award of $300, $200, and $100 for first, second, and third place.  These awards are presented during the Div. C02 Business Meeting by Div. C02 representatives.
