| Learning outcomes and their assessment | |
| Knowledge about the nature of organic farming, common and diverse with integrated production method, about transitional period towards organic farming, organic production of arable crops, vegetable and fruits, about seed cultivation and honeybee production in organic bee keeping conditions.
Skills: to develop plan of measures for the transitional period to organic farming method, plan for arable crop rotation and cultivation of horticultural plants under organic conditions. To equip, maintain and improve bees in accordance with biological principles. To select suitable for organic farming varieties and seed of good quality. Students are competent to apply and evaluate the conformity of cultivation technologies of the arable and horticultural crops including conformity of pedigree seed and bee keeping principles of the organic farming system. 1.Is able to prepare plan for changes in the farm during the transitional period to biological agriculture – test. 2.Students are familiar with crop-growing technologies in the organic farming system – quiz 1. 3.Students demonstrate skills in planning arable crops and grassland crop rotation – practical work 4.Students are able to evaluate suitability of variety for use in organic farming and conformity of seed to demands of normative acts: – two practical works and quiz 2. 5.Students demonstrate skills in the preparation of a technological map optional for one fruit plant in the organic farming system – home work 6.Garden building and maintenance system in an organic garden – quiz 3 7.Students are familiar with characteristics of apiary in organic beekeeping – quiz 4. |
