  • Nutri-Beans By: Jessica Bishai May 3, 2010
  • Hypothesis
    • If different formulas like phosphorous, nitrogen, potassium, and iron are tested on the number of bean pods and flowers a plant produces, then nitrogen will work the best. Nitrogen is supposed to help plants with aboveground growth. Since bean pods and flowers are above the ground, the nitrogen will help them grow and produce the most.
  • Materials
    • 5 large water-proof containers
    • 50 16-oz plastic cups
    • 1 bag of “Scott’s” potting soil
    • 6 1- liter bottles
    • 5 medicine measuring cups
    • 1 bottle of “Rite-Aid®” Phospha-Lax
      • (dibasic sodium phosphate 0.9 g and monobasic sodium phosphate 2.4 g)
    • 1 bottle of “CareOne®” Natural potassium tablets.
      • (99 mg per tablet).
    • 1 bottle of “LiveBetter®” iron tablets.
      • (27 mg per tablet)
  • Continued Materials
    •       1 bottle of “Wegman’s” Regular scent ammonia
    •       50 bush-bean ( Phaseolus Vulgaris) seeds
    •       Journal
    •       1 #11 surgical blade
    • 1 500 mL measuring cup
  • Procedures
    • 1.   Using a sharp # 11 surgical blade, carefully drill 3 small drainage holes at the bottom of each cup.
    • 2.   Divide the cups into 5 groups with 10 cups per group.
    • 3.   Label the cups as following
      • Group 1:Formula 1 (A through J)
      • Group 2:Formula 2 (A through J)
      • Group 3:Formula 3 (A through J)
      • Group 4:Formula 4 (A through J)
      • Group 5:Control (A through J)
  • Procedures Continued
    • 4.  Place each group in a separate water-proof container.
    • 5.  Place the containers in a well-lit room.
    • 6.  Fill each plastic cup ¾ of the way with potting soil.
    • 7.  Make a hole that is two-centimeters deep in the soil in each cup.
    • 8.  Place 1 seed in each hole and cover the seeds with soil.
    • 9.  Make the formula solution according to the Formula Recipe Chart .
  • Question
    • What is the effect of different nutrients (nitrogen, potassium, phosphorous, and iron) on the number of bean pods and flowers a bean plant produces?
  • Charts Chart 1
  • More Charts Chart 2
  • Even More Charts Chart 3
  • Data Summary
  • Observations Insect Infestation Stem thicknesses Iron on left, Control on right
  • Observations Bean pods Flowers
  • Conclusions 1 Hypothesis rejected
    • Hypothesis was that the nitrogen group would have the highest number of bean pods and flowers, highest germination rate and highest survival.
    • The data did not support the hypothesis.
    • The nitrogen group had fewest flowers and pods
    • The rate of germination for the nitrogen group was the same as the control group at 40%
    • Nitrogen group had lowest survival
    Conclusions 2 Poor outcomes with Nitrogen
    • The leaves of all groups of plants were extremely thin, opalescent, and slightly sticky.
    • The flowers were all about a centimeter in length and of a very light purple in color.
    • Stems of the iron plants had the greatest average diameter
    Conclusions 3 Observations
    • Despite nitrogen’s known value to other plant types, its low impact on the bean plants in this study may be due to the ability of beans to fix their own nitrogen from the air.
    Conclusions 4 Why Nitrogen had poor outcomes
  • Limitations
    • Small sample size.
      • Potentially large margin of error in computing germination and survival rates.
    • Unknown which nutrient concentration promoted optimum growth.
    • Insect infestations during mid-cycle.
    • Experiment was carried out in a room with its temperature set at 62ºF.
      • May have enhanced the disadvantage of those weaker plants in their productivity and survival.
    • Adding nitrogen to the soil may not be essential for beans
      • Bean plants are known to fix nitrogen.
    • Phosphorous helped the plants germinate earlier and survive longer.
      • Phosphorus known to promote root health
    • This information may be beneficial to the farming industries of the future, or even a simple home gardener.
