Promotion of Growth, Chlorophyll Content and Yield of Rice by a New Drug at Ultra High Dilution

Application of synthetic fertilizers reduces natural fertility of soil and contaminates ground water. Some photosynthesis inhibitors at ultra-high dilution (UHD) increase photosynthesis, growth and yield of crops. A weedicide Paraquat at UHD enhanced growth and yield of potatoes in fields. This weedicide was serially diluted with distilled water and manually succussed in 30 steps following the method of preparation of homeopathic dilutions called potencies. In this way the 30th potency of Paraquat called Paraquat 30cH was prepared and preserved in 90 % ethanol. Paraquat 30cH was diluted with water 1:1000 (v/v) and sprayed on rice plants in a field measuring 0.3125 acre. The control plot of the same area was situated 300 meters away from the test plot. Three treatments were given at an interval of 7 days. Treated plot showed increased growth, chlorophyll content and yield of rice significantly as compared to control. The UHD of the weedicide produced exactly the opposite effect of the crude material on plants. The increased growth and yield of rice by Paraquat 30cH may be due to enhancement of photosynthesis of treated plants. The UHD of Paraquat increased yield of rice by 19.35% over the control.
