Unit Of Agronomic Research And Variety Testing

Goal: To develop and adapt environmentally friendly horticultural crop cultivation systems and technologies to provide sectoral aid in order to ensure production efficiency.

Activity directions:

  • Horticultural crop technology research, development, and adaptation for fruit crops (fruits and berries) and vegetables, incl. fruit crop training, propagation, risk-reducing technologies, provisions of growth conditions (soil moisture regulation, irrigation, orchard maintenance, covering systems);
  • Fruit tree, berry and vegetable cultivar and fruit tree rootstock, cultivar rootstock combination evaluation;
  • Horticultural crop physiology research and solutions - to improve winter-hardiness, to provide photosynthesis efficiency, plant growth, and production regulation;
  • Plant provisioning (incl. nutrients and moisture), study of soil resource, influence of soil properties and sustainable soil usage for horticultural crops;
  • Sectoral aid - incl. consultations, seminars, training, practical lessons.

Research directions that the unit is taking part in: 

  •  Diversification and breeding of horticultural crop cultivars suitable for Baltic Sea Region;
  •  Environmentally-friendly horticultural production systems;
  •  Storage and processing technologies of horticultural crops;
  •  Basic biological research for horticulture science
