Course abstract

Students acquire knowledge of certain crop species and varieties morphological and biological characteristics, the regularities of yield and quality formation in different soil and meteorological conditions. Acquires planning of crop production measures and evaluation of the quality of the obtained crop yield.

Learning outcomes and their assessment

• Knowledge on the most economically important crop species in Latvia, their agro-ecological requirements, cultivation techniques and possibilities of use. Knowledge is confirmed by successfully passed test.
• Skills to recognize and distinguish crop species in different phases of plant development, to choose species and varieties suitable for growing conditions, to analyze the influence of various factors on crop yield and quality. Skills are strengthened in laboratory work and independent work.

• Competence to choose the most suitable growing technology on the specific conditions for obtaining the planned yield.

Requirements for awarding credit points

Test with a mark. The student must have completed and passed all laboratory works, defended independent work with an oral presentation and successfully passed a test with a score in grades.

Description of the organization and tasks of students’ independent work

Independent work includes literature studies, preparing independent work and strengthening knowledge, preparation for the seminar (oral presentation), processing and formating of laboratory work results.

Criteria for Evaluating Learning Outcomes

Student may take a test with a mark if the independent work and laboratory works have been accepted. The mark in the study course consists of mark in the test.
