Аннотация:Abstract. Electron beam (EB) radiation technologies have been employed to increase
efficiency of biologically active nanochips developed for agricultural plants seed pre-treatment
with purpose of enhancing crop yield and productivity. Iron-containing nanoparticles (NPs),
synthesized in reverse micelles following known radiation-chemical technique, have served as
a multifunctional biologically active and phytosanitary substance of the chips. Porous chip
carriers activation has been performed by EB ionization (doze 20kGy) of the active carbons
(AC) prepared from agricultural waste and by-products: Jerusalem artichoke (Helianthus
tuberosus) straw, rape (Brassica napus L. ssp. oleifera Metzg) straw, camelina (Camelina
sativa (L.) Crantz) straw, wheat (Triticum aestivum) straw. Three methods, UV-VIS
spectrophotometry, Electron Paramagnetic Resonance (EPR) spectroscopy, cyclic voltammetry
(CV) have been used for process control and characterization of radiation-activated and NPsmodified
ACs. The results show a notable effect of ACs activation by electron beam radiation,
evidenced by FeNPs-adsorption capacity increase. Studies of the impact of Fe NPs-containing
nanochip technology on enhancement of seeds germination rate and seedlings vigour suggest
that reported electron beam radiation treatment techniques of the ACs from selected
agricultural residues may be advantageous for industrial application.
