Effects of Crushed and Uncrushed fertilizers on Brassica rapa Number of Leaves Produced and Stem Height
Intro: The conducted experiment is to determine whether crushed or uncrushed fertilizers affect the overall growth of the Brassica Rapa. Each week the the the stems of the plant well be measure, the leaves will be counted and the information will be kept in a log. The hypothesis stated that crushed fertilizer would lead to more leave been produced and a longer stem length.
Materials & Methods: Quad wicks were placed inside of each quad of two different styrofoam planting quads through a small hole at the bottom of the styrofoam. Potting soil was added and filled to the top of each individual quad of both styrofoam boxes. A seed is dropped in each quad of the two Styrofoam planting quads and gently pressed down with the index finger. With both the styrofoam planting quads one uncrushed 14-14-14 NPK fertilizer bead is placed into two different quads and one crushed 14-14-14 NPK fertilizer bead is placed in the other two quads. Each styrofoam planting quad had two uncrushed and two crushed fertilizer beads planted. Each crushed and uncrushed fertilizer bead was gently pressed down into the soil with the index finger. An anti-algal square is added to the plastic water container with wick cloth which was used to water the plant daily. Each week for four weeks the Brassica rapa stems were measured in centimeters with a ruler and the the number of leaves were counted. Then logged the new stem height and production of leaves into a notebook. Microsoft Excel was used to input the logged information over the four weeks. Microsoft Excel averaged and sorted out the weekly results of the Brassica rapa. Two graphs were created from excel. One graph stating the effects of stem height from the uncrushed and crushed fertilizer beed. The second graph stating the effects of uncrushed and crushed fertilizer beads on the
