For many years farmers have been using hydrogen peroxide to increase crop yields They suggest mixing five to sixteen ounces of 35 hydrogen peroxide with twenty gallons of water for every acre of land Botanists suggest mixing one ounce of 3 hydrogen peroxide with a quart of water to improve the health of plants Jims The farmers solution calculates to be between a 068 and a 217 percent concentration of hydrogen peroxide while the botanists solution calculates to be about a 1765 concentrationIn the experiment the experimenter will mix progressive amounts of a 3 hydrogen peroxide solution with water and use this to water tomato plants over a 31 day period while periodically measuring their growth They should use ten different concentrations of hydrogen peroxide 000 Row A 033 Row B 067 Row C 100 Row D 133 Row E 167 Row F 200 Row G 233 Row H 267 Row I and 300 Row J This should tell them whether or not hydrogen peroxide is beneficial to plants and if there is an optimal concentration which facilitates maximum plant growth To analyze the data they should compare the differences from starting height to final height One may expect the plants receiving higher levels of hydrogen peroxide to grow larger than those receiving less hydrogen peroxide because the increased oxygen in the soil will help plants to absorb more nutrients Although farmers suggest using a 35 solution the experimenter should use a 3 solution because it is cheaper more readily available and is the maximum concentration they will be using for this experimentCherif M Tirilly Y Belanger R R 1996 Effect of Oxygen Concentration on Plant Growth Lipidperoxidation and Receptivity of Tomato Roots to Pythium F Under Hydroponic conditions Retrieved November 07 2010 from Metapress httpwwwresourcesmetapresscomEffect of Dissolved Oxygen Concentration on Lettuce Growth in Floating Hydroponics 1996 Retrieved November 07 2010 from PubMed httpwwwncbinlmnihgovHow to mix and apply Hydrogen Peroxide in Gardening 2007 Retrieved
