Vigna Unguic Acid On Plant Growth Essay
2013 Science Research Project:
The Effect of Calcium on Plant Growth
Problem Statement
What affect do various amounts (0 mg, 300 mg, 600 mg) of Calcium added to Vigna unguiculata (black eyed pea plants) once a week have on the overall growth (height, number of leaves, number of pods) over a 30 day period of time?
Research Hypothesis
If various amounts (0 mg, 300 mg, 600 mg) of Calcium are added to Vigna unguiculata (black eyed pea plants) once a week, then those plants receiving 300 mg of Calcium will have a greater overall growth (height, number of leaves, number of pods) over a 30 day period of time.
Null Hypothesis
The various amounts of Calcium added to Vigna unguiculata (black eyed pea plants), will have no effect on their overall …show more content…
For the first 5 days of the experiment, allow the plants to germinate by watering them with 50 ml of water everyday. In a chart or data table, mark the day of the experiment that each plant started to germinate.
22. On the eighth day, use a metric ruler (or measuring tape) to measure the growth height of each plant in centimeters. Record the heights on the data table.
23. Next, count the number of leaves for each plant. Record these numbers on the data table.
24. Count the number of pods, if any. Record these numbers on the data table.
25. Take twelve 600 mg Calcium tablets (7,200 mg total), or 1 tablet for each plant in the 600 mg group. Crush up the tablets.
26. Pour 600 ml of water into a 1 gallon jug or bottle, or 50 ml for each plant in the 600 mg group. Dissolve the powder of the tablets into the water.
27. Pour 50 ml of the solution over the soil in the cup labeled 1 – 600mg.
28. Repeat for each cup in the 600 mg group.
29. Take six 600 mg Calcium tablets (3,600 mg total), or half of one tablet for each plant in the 300 mg group, making each tablet 300 mg. Crush up the tablets.
30. Repeat steps 26 through 28, replacing the 600 mg group for the 300 mg group.
31. Take 50 ml of water and pour it over the soil in the cup labeled 1 – …show more content…
The hypothesis was that those plants receiving 300 mg of Calcium would have greater overall growth over a 30 day period of time.
Thirty-six 452.8 g (16 oz.) cups were filled with 367.9 g (13 oz) of potting soil. Twelve of the cups were labeled 1 – 0mg through 12 – 0mg, another twelve 1 – 300mg through 12 – 300 mg, and the last twelve labeled 1 – 600mg through 12 – 600mg. two black eyed peas were placed in each cup. All seeds were watered with 50 ml of watered everyday for the first seven days. On the eighth day, measurements were recorded and the seeds were watered with their appropriate Calcium solution, based on their labels. This was repeated once every week for 3 weeks.
The plants watered with 0 mg of Calcium (Group A) had the greatest overall growth height of 17.86 cm. The plants watered with 0mg and 300 mg of Calcium both had the greatest overall number of leaves, with 5.31 leaves. This concluded that lower concentrations of Calcium are more beneficial to plants than higher concentrations of
