About this course

The subject deals with how different factors affect the yield in plant production. The focus is at the crop level rather than the individual plant level. Light energy, water and nutrition. Photosynthesis, photorespiration and respiration. Growth and Development. Allocation of assimilates. Limiting factors. Product quality. Models that simulate yield development.

Learning outcome


You can describe qualitative and quantitative relationships determining how light energy, water and nutrition can be transformed to plant products. You can explain how this is controlled by traits and processes in plants, management and other environmental factors.


You can determine the developmental stage of some common agricultural species.

Generell kompetanse:

You have a basic understanding of the relationships between environmental factors, plant development, yield and quality of the harvested product. This enables you to learn more about how management can be optimized, how prediction models for yield and quality function, and how selection for certain traits through plant breeding can result in cultivars with higher yields or a different quality.

  • The subject consists of lectures, exercises with problems and questions, and a practical excercise throughout the semester where the students conduct their own experiment in the greenhouse and measure plant development. A lab report must be submitted.
  • Lectures, information about the practical excercise, study questions and other information will be available in Canvas.

  • An external evaluator will approve the exam questions and contribute to the appraisal of examination papers
  • Practical excercise. Submission of journal.
  • 2 hours per week, altogether approx. 30 hours.
