Classroom module 1 (half day) –

  • Link between crop management and potato growth and development;
  • Characteristics of potatoes (e.g. clonal, perishable);
  • Growth keys (e.g. BBCH);
  • Seed (dormancy, apical dominance, physiological and chronological age, sprouting, storage temperature, pathology, size, cutting);
  • Emergence (soil temperature, planting depth, pathology);
  • Above-ground morphology (main stems, branches, flowering);
  • Below-ground morphology (roots, stolons, tubers);
  • Root growth (soil conditions, variety);
  • Leaf appearance (temperature, variety, nutrition);
  • Tuber initiation (definitions, timing, duration, variety);
  • Crop cover (leaf area index, ground cover);
  • Dry matter accumulation (radiation use efficiency, water, pathology);
  • Partitioning of dry matter (nitrogen, variety, time, harvest index);
  • Development of yield (rate of bulking, factors affecting);
  • Tuber dry matter concentration (variety, nutrients, change with time);
  • Tuber populations (relation with stem population, variety, environment);
  • Tuber size distributions (mean tuber size, uniformity, marketable yield);
  • Senescence and harvesting (haulm destruction, skin set, bruising);
  • Storage (suberisation, weight loss, pathology, biochemical changes).


PLEASE NOTE:PR14 Scheduling irrigation to optimise yield and quality in potatoes runs in the afternoon (from 01:30 pm) the same day.  Book both courses for a full day of training.
