In many countries, the possibilities for stimulation of the sowing qualities and yield of cultivars after pre-sowing electric treatment of their seeds have already been identified.
At the University of Ruse, Bulgaria, for more than 20 years studies have been conducted on the pre-sowing stimulation of the sowing qualities of seeds of various agricultural crops that are subjected to pre-sowing electromagnetic treatment.
This article discusses the preliminary results of pre-sowing electric (electromagnetic and electrostatic) treatment of pea seeds.
It has been established that after electro-magnetic or electrostatic pre-sowing treatment it is possible to obtain a stimulant effect on pea seeds. This effect takes place after 14 days of rest from treatment to sowing, and with the other controllable factors has following values:
- for the three-step electromagnetic treatment initial value of the applied voltage is U1 = 4 kV, and duration of treatment 1 = 5 s;
- for the electrostatic treatment voltage is U = 6 kV, and duration of treatment = 70 s.
The treatment applied to pea seeds leads to an increase in the germination capacity by 2,6%, in the length of the sprouts by up to 5,5% and of the rootlets by up to 18,6%, and increase in the mass of the plants by 6,9% as compared to the reference specimen. U mnogim zemljama su već identifikovane mogućnosti za stimulisanje setvenog kvaliteta i prinosa sorti posle električnog tretmana semena pre setve.
Na Univerzitetu u Ruse, Bugarska, više od 20 godina se sprovode istraživanja stimulacije kvaliteta semena, elektromagnetnim tretmanom pre setve, kod raznih poljoprivrednih kultura.
Ovaj rad predstavlja preliminarne rezultate električnog (elektromagnetnog i elektrostatičkog) tretmana semena graška.
Utvrđeno je da je posle elektro – magnetnog ili elektrostatičkog tretmana pre setve moguće postići stimulativni efekat na seme graška. Ovaj efekat se ispoljava 14 dana posle tretmana za setvu, a drugi kontrolisani faktori imaju sledeće vrednosti:
- za tro-stepeni elektromagnetni tretman inicijalna vrednost primenjenog napona je U1 = 4 kV, a vreme trajanje tretmana 1 = 5s;
- za elektrostatički tretman napon je U = 6 kV, a vreme trajanje tretmana = 70 s.
Tretman primenjen na seme graška dovodi do povećanja kapaciteta klijanja od 2,6%, dužine klijanaca do 5,5% i korena do 18,6% i povećanje mase biljaka od 6,9 %, u poređenju sa referentnim uzorkom.
