Languages of instruction


•Introduction – essential mineral nutrients for crop growth
•Nutrient acquisition and translocation (biomembranes and selectivity of nutrient uptake, mechanisms of xylem and phloem loading/unloading)
•Crop yield and source-sink relationships
•The role of phytohormones in source-sink relationships
•Mineral nutrition and crop yield response
•Functions of macro- and micronutrients
•Root architecture and nutrient acquisition
•The concept of nutrient-use efficiency in crop production


Objective (expected results of study and acquired competences)

Following the completion of this lecture on crop nutritional physiology, the students will:
•explain the detailed mechanisms involved in the selective uptake of mineral nutrients by plant roots;
•describe the biochemical and physiological functions of macro- and micro- nutrients;
•identify the deficiency symptoms of mineral nutrients in a wide range of crop plants;
•define root architecture and explain the relationships between root architectural traits and acquisition of mineral nutrients;
•apply the acquired theoretical knowledge on crop nutritional physiology to analyse quantitatively the options for improving nutrient-use efficiency in crop plants.
