Laboratory of plasma applications in agriculture


Plasma source:

Plasma reactor based on DCSBD modified for treatment of plant seeds generating low temperature plasma in ambient air (N2, CO2, O2) at atmospheric pressure


The main aim of research 

  • The design, construction and verification of the prototype plasma device based on low-temperature plasma
  • Treatment of plant seeds for sowing (cereals, legumes, nuts, spices and other) and stored agricultural commodities (mainly cereals, nuts, dried fruits) destined for human nutrition of the population as well as for farm animals
  • The study of the plasma effects on growth, physiological, biochemical, molecular and anatomy-structural aspects of plants seeds after seed plasma treatment
  • The diagnostics of low-temperature plasma using optical and electrical methods and the assessment of correlation between the plasma parameters and the optimal plasma effects on the surface of biological materials






  • cereals (maize, wheat, barley)
  • legumes (peas, soyabeans, beans)
  • spices (black pepper)
  • nuts (hazelnuts, peanuts)


Diagnostics of plasma influence on biological material

  • Physiological properties
    • Germination and growth parameters
  • Decontamination of surface
    • Influence of plasma on native and artificial microcenosis
  • Content of biological active compounds
    • Antioxidants and oxidative characteristics
    • Qualitative parameters of oil in nuts
    • Detection of piperine in pepper
  • Physical (surface) properties
    • Surface wettability – WCA, imbibition
    • Influence of plasma on surface morphology – SEM
    • Changes in chemical bonds – ATR –FTIR
    • Ageing of plasma treatment
