Micronutrients are part of enzymes and play an important role in plant germination.
Purpose of our study was to establish the effect of pre-seed treatment of chufa tubers with metal
nanoparticles on the growth of the root system and seedlings in the early stages of development.
Laboratory tests were performed on seed of tiger nut cultivar Pharaoh. Experiment involved two
methods of treatment: pre-sowing treatment of seeds with nano-particles solutions of manganese,
zinc, copper and iron with a concentration of 60 ppm and re-application of these solutions after
seedling emergence. The weight of seedlings and roots was determined at 3rd and 10th days after
emergence in treated and untreated variants. Pre-sowing treatment of chufa tubers with all forms
of micronutrients significantly increased the weight of the plant (excluding the weight of seeds),
and the most effective were treatments with copper and iron. Treatment with copper colloidal
solution increases in root weight at 3rd day on 156% compared to control without treatment and
this dynamic stayed at 10th day. Most affective treatment is iron colloidal solution. This treatment
gives +99% of root weight at 3rd day and 194% at 10th day after germination compared to control
in same time. Colloidal forms of manganese, copper and iron also significantly increased the
weight of the shoot. Increase in the mass of roots, shoots and plants is observed in plants with
foliar fertilizing, but a few variants have an insignificant difference or inhibit the assimilation
processes of plants. Pre-sowing treatment with zinc citrate at 60 ppm decreased root and shoot
weight in chufa.
