ELECTROCOLTURE
The U.S. Bureau of Plant Industry recently completed a series of experiments, extending over a period of ten years, to determine whether trical treatment of plants results in a stimulation of growth or an inoreased yield of grain. Experiments were made with wheat grown in field plants at" the Arlington, Va., farm of the Department of Agriculture and in a greenhouse "Washington. In most oE the experiments an insulated network suspended above the plant* • was kept charged for several hours each, day to a, high positive potential; a procedure claimed by some European investigators to give an increased, yield. lu.addition \o the direct-current experiments, rapidly alternating currents were applied 'to the network. . The effect of the ordinary alternating-current, power line attached to the network was also tried. The bureau has in preparation a bulletin giving the results of the experiments, whioK have now been discontinued. Briefly stated, the conclusions are that an electrostatic field has very little influence upon plant growth. In no oase has a definite and positive stimulation resulted from electrical treatment.
