Abstract
This research aims to study of the effect of static electric field on germination rate and seedling
growth of Kao Jao Deng from Lao PDR. Including the study of the intensity of the electric field and the
appropriate time to exposure the rice seeds. The sample rice seeds were subjected to the electric field
at 0.5, 1 and 5 kV/m and exposure time 1, 5, 10, 20 and 30 minutes, respectively. The efficiency
Indicator calculation of the germination and growth of the rice seeds such as final germination
percentage, seedling growth, germination index and vigor index. The results shown that exposure to 10
minutes of electric field of 1 kV/m compared with the control, the final germination percentage,
seeding growth, and vigor index increased by
