Sample of a scientific study
Prepared by: D. C. Tabinga, Jr.
Definition of Terms
• Pechay-(Brasicca pekinensis)
• Sagana 100- a commercialized organic fertilizer.
Prepared by: D. C. Tabinga, Jr.
Problem
• The effect of Sagana 100 organic fertilizer on the growth and yield of pechay (Brassicapekinensis)
• Dependent variable: Growth and yield of Petchay
• Independent variable: Sagana 100 organic fertilizer.
Prepared by: D. C. Tabinga, Jr.
Observation
• It was observed that soil becomes hard after years of applying commercialized synthetic fertilizer.
• Compared when using commercialized organic fertilizer the natural composition of the soil is maintained.
• Does using commercial organic fertilizer has an effect on the growth and yield of a plant
Prepared by: D. C. Tabinga, Jr.
Hypothesis
• It has no effect on the growth and yield of Petchay
• It will increase the growth and yield of petchay
• It will decrease the growth and yield of petchay

Experiment
• Plots were prepared equally
• The amount of the following is the same:
• sun,
• Water
• demography
• The number of seedlings

Experiment
• A control treatment is assigned.
• Treatments were assigned according to the amount of fertilizer used.
• T1-Control• T2-2 kg• T3-4 kg• T4-6 kg
Prepared by: D. C. Tabinga, Jr.
Experiment
• The treatments were randomly applied
Prepared by: D. C. Tabinga, Jr.
Experimentation
• For about a month the following data were collected per plot:
• Height of the plant
• No. of leaves
• Width of Leaves
Prepared by: D. C. Tabinga, Jr.
Experimentation
• When the plant was harvested. The following data was gathered:
• Weight of the plant per individual.
• Weight of the plant per plot
• No. of plant harvested per plot.
Prepared by: D. C. Tabinga, Jr.
Conclusion
• After the experiment it was found out that the higher the amount of organic fertilizer applied. The higher effect on the growth and yield of petchay.
