Course abstract

A course project has been developed with the task to get acquainted with the agrotechnics and technology of growing planting material of the main forest tree species, starting with seed collection and ending with preparation of seedlings and plants for forest regeneration, covering the full forest nursery cycle. Students get acquainted with an insight into the organization of nursery work, basic positions for calculating costs and production costs.

Learning outcomes and their assessment

The study course develops knowledge and understanding of the practical course of forest tree planting material production in forest nurseries, students acquire planning skills based on the theoretical course on seed collection, quality, storage and planting material growth, as well as vegetative propagation methods. Students are competent and prepared to work as specialists in the propagation and cultivation of reproductive material in forest nurseries. Students prove the acquired knowledge, skills and competencies by developing, designing and successfully defending a course project.
