The growth of dwarf peas, Pisum sativum, depends on soil and seed characteristics. Sterile conditions will have a positive effect on the physiology of P. sativum below and above the soil. The length, width of roots, and number of leaves of plants will be positively affected by sterile conditions because pathogens in the soil that compete with the plant for its nutrients will be killed. The soil and some seeds were sterilized and grown for twenty-one days before the parameters of root length and width and number of leaves were tested. Of the three parameters, root length was the only one affected by sterile conditions. No changes in other parameters were observed because more growth time was required for P. sativum plants. IntroSoil is one of the largest contributors to plant growth because it is made up of nutrients such as potassium, nitrogen, phosphorus and living organisms. In the vast plant world, some living organisms in soil and plants such as rhizobia, which are the bacteria that provide sufficient nodulation in legume crops” (Mathew, David, & Mark, 2013) are useful. It is these important rhizobial bacteria located in the root nodules of plants that help the plant fix nitrogen. Other living organisms such as nematodes and parasites are harmful to plant health. Harmful living organisms in the soil rob plants of their resources and nutrients, leading to nitrogen and sulfur nutrient deficiencies. In highly valued nutritious food plants such as dwarf peas, Pisum sativum which contain an abundant content of essential elements such as starch; the presence of pathogens in the soil will lead to low nutritional value in dwarf peas. To overcome challenges in soil and seeds that negatively affect...... middle of paper ......et. An example of this is observed through the parameters provided in the experiment. Although some parameters were not met, root length was affected by soil sterilization. Works CitedMathew, D., David, P., & Mark, P. (2013).
