AGRI2001: Plant Management in Agroecosystems

Semester 1, 2021 [Normal day] - Camperdown/Darlington, Sydney

World population is projected to reach 9 billion within 50 years and food production needs to double in a sustainable manner in order to feed human population. This profound challenge will be met by improving our knowledge and management of agroecosystems. This unit of study is designed to provide an introductory understanding of the biology and management of plants in dryland agroecosystems, with a focus on major Australian broad acre crops. Dryland agroecosystems can be defined as ecosystems modified for the purpose of producing crops, pastures and animals in environments where water limits productivity during part of the year (and are typical in Australian agriculture). These agroecosystems are characterised by regular agricultural interventions, such as cultivation, sowing, nutrient, weed, pest and disease management, and harvest. The program will involve developing an understanding of the interactions between the environment, crops/pastures and agricultural management in dryland agroecosystems. The model for describing and analysing agroecosystems will be centred on a typical cropping cycle, with an emphasis on cereals. You will gain knowledge and skills on crop physiological, growth and development responses to the combined climatic, edaphic, biotic and management factors in the growing environment. The unit will also provide a sound understanding and analysis of the practical farming framework in which this knowledge is applied through weed, disease and pest management, approaches to managing climate variability and precision agriculture. There will be a focus on assessing the effects of climate and weather in dryland agroecosystems, especially on understanding crop-water-nutrition relationships. Successful students will be able to appreciate and analyse the most important limitations to crop production and yield in Australia and how those limitations can be minimized or overcome through science-based planning and agronomic management practices.

Assessment summary

  • Three short-answer quizzes: Quizzes that reinforce the topics covered in the previous weeks.
  • Report: The report is designed to support you in integrating your growing understanding of crops and their response to the environment, and being able to describe and discuss this understanding in a clear manner. The report topic will be discussed in class early in the semester.
  • Exam: The exam will consist of a combination of short-answer and essay type questions to cater for different learning styles. All lectures, tutorials and practical sessions are exam-relevant.
Detailed information for each assessment can be found on Canvas.

Assessment criteria

At HD level, a student demonstrates a flair for the subject as well as a detailed and comprehensive understanding of the unit material. A ‘High Distinction’ reflects exceptional achievement and is awarded to a student who demonstrates the ability to apply their subject knowledge and understanding to produce original solutions for novel or highly complex problems and/or comprehensive critical discussions of theoretical concepts.

Distinction

75 - 84

At DI level, a student demonstrates an aptitude for the subject and a well-developed understanding of the unit material. A ‘Distinction’ reflects excellent achievement and is awarded to a student who demonstrates an ability to apply their subject knowledge and understanding of the subject to produce good solutions for challenging problems and/or a reasonably well-developed critical analysis of theoretical concepts.

Credit

65 - 74

At CR level, a student demonstrates a good command and knowledge of the unit material. A ‘Credit’ reflects solid achievement and is awarded to a student who has a broad general understanding of the unit material and can solve routine problems and/or identify and superficially discuss theoretical concepts.

At PS level, a student demonstrates proficiency in the unit material. A ‘Pass’ reflects satisfactory achievement and is awarded to a student who has threshold knowledge.

Fail

0 - 49

When you don’t meet the learning outcomes of the unit to a satisfactory standard.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.  

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Attendance and class requirements

Due to the exceptional circumstances caused by the COVID-19 pandemic, attendance requirements for this unit of study have been amended. Where online tutorials/workshops/virtual laboratories have been scheduled, students should make every effort to attend and participate at the scheduled time. Penalties will not be applied if technical issues, etc. prevent attendance at a specific online class. In that case, students should discuss the problem with the coordinator, and attend another session, if available.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Required readings

You should use a variety of sources including texts and journal articles in your learning and preparation for the exam. Other resources will be available on the Unit of Study LMS website.
