In particular the course provides a practical understanding of selection, establishment, management and utilisation of crops and pastures in the main rainfall and soil environments encountered in southern Australia. Topics include: weed, pest and disease management; species and cultivar identification and selection; selection and use of crops and pastures; rotations; tillage; nutrition and fertilisers; and the interrelationship of agronomy and the environment.

Learning & Teaching Activities
Learning & Teaching ModesThe course material is taught by a combination of lectures, tutorials and practical classes, with formative assessment exercises in the form of practical write-ups, tutorial presentations and summative assessment in the form of one examination. The lectures are organised into three streams. The first of these are lectures that cover major principles related to sustainable and profitable crop production. The second stream covers constraints and production practices for important field crops in southern Australia. The third stream addresses the role and adaptation of pastures to the environment and management practices for their management. Lecture modes used are based primarily on traditional classroom paradigms of lecturer-student interactions, using PowerPoint or similar presentation techniques.
Practical classes and tutorials are designed and timetabled such that as far as possible, the topics co-ordinate with those being taught at that time within the lecture stream. One of the practical sessions will be used as a test on describing crop growth stages and ability to dissect and display apical meristem of wheat. Students will work in small groups to collect data on crop growth and development in the field and at the end of the semester all groups will submit and brief research paper on their findings.
There will be 3 tutorial sessions during the semester. In the first, students will be guided in the methodology required for data analysis from their field study. In the 2nd tutorial, student will work in groups and each group will be given data on yields trends and rainfall at Roseworthy farm. Student groups will analyse the data and make a PowerPoint presentation at a later date to describe the results and provide an interpretation of the likely reasons for seasonal differences in productivity.
Feedback is provided on all assessed work.
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.A student enrolled in a 3 unit course, such as this, should expect to spend, on average 12 hours per week on the studies required. This includes both the formal contact time required to the course (e.g., lectures and practicals), as well as non-contact time (e.g., reading and revision).

2. Scenario-based learning on Australian dryland pastures
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
Assessment Task Task Type Due Weighting Learning Outcome Group reports on water use efficiency of field crops grown on Roseworthy farm Summative

There will also be five summative assessment components related to practicals:
Assessment of crop growth and development pattern in the field (wheat, barley, beans and canola) - 10 marks
Effect of seed rate (crop density) on growth and development of barley - 10 marks
Weed collection - 10 marks
Trends in productivity and water use efficiency of crops (small group work with oral presentation) - 10 marks

SubmissionAssignments should be submitted with a cover sheet available from MyUni. Feedback will be provided within two weeks after the submission date.
Late submission of assessments
If an extension is not applied for, or not granted then a penalty for late submission will apply. A penalty of 10% of the value of the assignment for each calendar day that is late (i.e. weekends count as 2 days), up to a maximum of 50% of the available marks will be applied. This means that an assignment that is 5 days or more late without an approved extension can only receive a maximum of 50% of the mark.
Grades for your performance in this course will be awarded in accordance with the following scheme:
M10 (Coursework Mark Scheme) Grade Mark Description FNS Fail No Submission F 1-49 Fail P 50-64 Pass C 65-74 Credit D 75-84 Distinction HD 85-100 High Distinction CN Continuing NFE No Formal Examination RP Result Pending
Further details of the grades/results can be obtained from Examinations.
Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.
Final results for this course will be made available through Access Adelaide.
The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
