The Effect of Nutrient Input Method on the Root Mass of Raphanus sativus

The effect of nutrient input on the root mass of Raphanus sativus will be determined during experimentation. After inputting the four nutrients Potassium Gluconate, Calcium, Vitamin B1 and B12 using four different methods which used the same amounts of the nutrient, and a standard without any input, the plants would be extracted from their planting cells and washed of any dirt. Once the plant had been fully washed the roots would be severed and massed to a 0.0001 precision. The researcher hypothesized that a heterogeneous mixture of nutrients being present in the soil prior to planting will yield the greatest root mass. These different data sets would then be compared using a two sample t-test in order to determine which method yielded the greatest results in root mass, the results from the two sample t-test allowed for the researchers to reject the hypothesis and it was revealed that a heterogeneous mixture of soil, Potassium Gluconate, and Calcium along with liquid dosages of Vitamin B1 and Vitamin B12.
