The study aimed to investigate the effect of the application of external electric field on the growth and development of genotype Gm34 of guar (Cyamopsis tetragonoloba L.) plant. This effect is expressed in terms of electric energy density created within pairs of copper plates forming electric capacitors in a DC current circuit connected to an electric source. The system was designed and used for experimentation with 1500 cm2 plate area connected with six volts. Seeds of C. tetragonoloba were located within spaces (30 cm) between capacitor's plates and were given 6 volts electric potential. The results showed that when genotype Gm34 was supplied with 6 volts (0.2 V/cm) in different plant growth stages during a period of 21 weeks; the highest percent increase in plant height, number of leaves, number of branches and stem diameter was obtained when plants were treated in vegetative stage. All treatments accelerated flowering and fruiting date.
