For the purposes of considering request for Reasonable Adjustments under the Disability Standards for Education (Cwth 2005), and Student Support and Engagement Policy, academic requirements for this subject are articulated in the Subject Overview, Learning Outcomes, Assessment and Generic Skills sections of this entry.

It is University policy to take all reasonable steps to minimise the impact of disability upon academic study, and reasonable adjustments will be made to enhance a student's participation in the University's programs. Students who feel their disability may impact on meeting the requirements of this subject are encouraged to discuss this matter with a Faculty Student Adviser and Student Equity and Disability Support: http://services.unimelb.edu.au/disability

The production of plant food and fibre involves the manipulation of plant growth and development to achieve desired levels of yield and quality. This subject considers how crop and pasture canopies grow by acquiring resources from the environment, how plants allocate resources to different growth processes, and how management and environment (including climate change) affect plant production in Australia and worldwide. Plant processes will be presented at the plant, canopy and community level, touching on the wider implications for water and nutrient management as they influence landscape processes such as salinity and soil acidification.

On completion of this subject students will:

• Be able to describe root growth and function, nutrient uptake, nitrogen fixation and explain the importance of plant nutrition in managing crops, as well as implications for nutrient run-off and water quality
• Be able to describe water uptake, transpiration, xylem flow, stomatal control and explain the implications of these processes for managing crop transpiration and soil evaporation in dryland cropping and under irrigation
• Be able to analyse biomass assimilation, translocation and storage from first principles of photosynthesis and light interception at the plant and canopy level, as well as the role of the phloem and carbon sinks in the partitioning of photoassimilates
• Know the critical steps and processes in plant development, and explain the pivotal role of flowering time (and the factors affecting it) in adaptation to stressful environments
• Better understand the abiotic factors affecting plant productivity and plant adaptations to these factors

• A two-hour examination to be held during the end-of-semester examination period worth 40%
• A 2500-word practical report due in approximately Week 4 worth 25%
• A 2500-word practical report due in approximately Week 11 worth 35%
