Course abstract

Biology and regions of distribution of fibre-crops (flax, cannabis, cotton etc.), oil-crops (rape, turnip rape, sunflower etc.), essential oil-crops (caraway, coriander, peppermint etc.), root-crops (sugar- and fodder-beet, Swedish turnip, turnips, carrots) and tuberous plants (potatoes, Jerusalem artichoke). Influence of ecological factors on above mentioned crops’ yield forming, changing of yield chemical structure and quality. Methods of growing, harvesting and storing; their agro-economical estimation. Ways of utilization of above mentioned crops. Seed production and certification of above mentioned crops.

Learning outcomes and their assessment

Knowledge – on biology and growing technology of fiber plants, oil, tuberous and root crops, and on use of their yield according evaluated quality, including for seed (1st, 2nd and 3rd test works).
Skills – to use growing technology according to biologic demands of field crops included in the study course, as well as to evaluated consequences of wrong technological method, to soften this negative effect with the next operation; to evaluate interaction of agronomic and meteorological factors and quality of crops for different purposes; to define the most appropriate way of crops’ yield use according the specific quality: for food, feed, seed or bio-energy (1st, 2nd and 3rd test works, accomplishment of task during study trip).

Competence – to manage production and/or advisory work, as well as to perform self-dependent scientific research using crops included into study course; to study and to analyze scientific and other literature on mentioned crops (prepared lecture).

17. Potato, beet, oil plant and fibre plant seed-production: variety and causes of their deterioration, seed-production legislation, seed certification: field inspection, seed quality evaluation, post-control, agro-technological peculiarities in seed-fields.

Requirements for awarding credit points

1. Write 3 tests (1. oil plants and fibre plants; 2. tuberous plants; 3. root-plants) with an approved result (at least 4 points);
2. Attend organised guest lecture and lectures prepared by group mates; if any of those is not attended, a report on its topic on the basis of at least 10 scientific articles published in English must be prepared (Word format). Assessment – passed.
3. Attends one visit with a task on any of plant groups.
4. Prepares 2 h lecture on pre-selected topic (about any plant from the course program), including the results of a scientific research in it.

5. The 2 h lecture provides 40% of the assessment, test results make up 39% (13% each test), attendance of lectures and outing, and the completion of the task –11%. The remaining 10% are obtained in an exam by answering one drawn lots question on course topic in detail.

Description of the organization and tasks of students’ independent work

1. Topic of lecture to be prepared – some examples of possible topics:
• Caraway, characterisation of their agro-ecological requirements and biology, growing methods, economic use, growing volumes (if any data present). Agro-technological peculiarities.
• Plants useful for sugar production. Characterisation, usage, growing areas in world, Europe and closest neighbouring countries of sugar beets; agro-ecological requirements for sugar beets, biological and agro-technological peculiarities.
• Characterisation of flax (oil and long-fibre), agro-ecological requirements, economic use and growing volumes in the world, Europe, Latvia; agro-technical peculiarities.
• Characterisation of hemp (Cannabis sativa), agro-ecological requirements, economic use, growing volumes in the world, Europe, Latvia (as much data as possible), agro-technical peculiarities.
• Characterisation of potato, agro-ecological requirements, economic use and growing volumes in the world, Europe, Latvia; agro-technical peculiarities, etc.

2. Visits with a task can be organised to VAAD, KS LATRAPS, AS Latfood, AREI Priekuļi Research Centre, Aloja Starkelsen, to any hemp processing plant, to SIA Naukšēni or elsewhere, agree with a study group.

Criteria for Evaluating Learning Outcomes

Works, assessed with passed/failed: work completed in accordance with requirements set out in the previous paragraph – visit with a task, attendance of guest lecture and group mates’ lectures.
Tests evaluated with a grade: evaluated according to the grade scale from 1–10.
The lecture is evaluated on a 10-point scale, focusing on such aspects:
1) The logic of layout and organisation;
2) Completeness of layout, providing information of the whole topic of the lecture;
3) Ability to use scientific articles;
4) Correct usage of professional and scientific terminology;

5) The whole group is evaluating.
