Course abstract

Principles of Precision Agriculture and their use in Horticulture – today’s achievements and future opportunities. Uses of GPS, GIS, sensors, variable-rate farming equipment etc. for differentiate plant cultivation procedures for intra- and inter-field variation. New, non-destructive quality control systems for growing, grading, storing and marketing horticultural produce. Advanced greenhouse horticulture – use of sensors, automatization, IT; energy-efficiency. Maximization of yield quantity and quality.

Learning outcomes and their assessment

1. In-depth knowledge of the principles of precision agriculture and their application in the production of high quality horticultural products in a modern company - lectures and seminars
2. Skills to evaluate the use of modern technologies in the production of horticultural products in relation to the type of production, the size and conditions of the enterprise, to plan various technologies of horticultural production, applying the latest scientific and technological achievements; to independently learn the latest information in the industry –individual work - seminar

3. Competences to understand and analyze scientific and professional information, to prepare presentations, to justify their decisions and to substantiate their opinion - seminar

Course Content(Calendar)

Requirements for awarding credit points

An exam.

Students, who have successfully presented their presentation in the seminar, can pass the exam.

Description of the organization and tasks of students’ independent work

Each student prepares a presentation (research of scientific and professional literature) for a seminars on a topic agreed with the lecturer from the course content. The work is presented to the student group at the seminar. Approximate length of presentation is 30 minutes. The student should be able to answer questions, discuss the topic and justify his / her opinion.

Criteria for Evaluating Learning Outcomes

The final mark consists of the exam mark (50%) and the mark from the seminar during the semester (50%).
