Electrostatic fields (E) may have biological effects due to redistribution of ions and weak currents they induce (in Cifra, M., Fields, J.Z., Farhadi, A., 2011’s journal review). The growth of Rice plant in vegetative phase between with and without E exposure with various of E directions is presented. The variations directions is (perpendicular with stem direction of growth), (in the same direction with stem direction of growth), , , and . This research is focused on the height of stems, the length of roots, and the wet masses of plants. Numbers of seed in each plastic box are controlled. They are exposed to an E for 2 days (46 hours) at the beginning of its growth and then stored in the open space. The changing of plants growth are observed every day last for 10 days. Growing is calculated by testing hypotheses about two population means. Experimental results indicate that the Rice plants growth in E with direction have a positive effect for the height of stems, the length of roots, and the wet masses of plants; E with direction have a positive effect for the height of stems and the wet masses of plants; both of E with direction and E with direction have a positive effect for the masses of seeds; and the E with direction have a positive effect for the height of stems. As for the positive effect of direction E against of mass accretion if sorted from the largest is , , , and ; the positive effect of direction E against of length of roots accretion only found in ; and the positive effect of direction E against of height of stems accretion is , , and .
