Study Notes
Research Problem
- Synthetic fertilizers negatively impact soil fertility and yield
- This study investigates molasses-fermented organic liquid fertilizer (MOLF) as a sustainable alternative
- The research will measure the impact of MOLF on scallion yield compared to synthetic fertilizers
Research Design
- Independent Variable: Application of MOLF
- Dependent Variable: Scallion Yield (measured by plant height, growth rate, and overall yield)
- Mediating Variables: Molasses, NPK levels in MOLF, and soil microbial activity
- Moderating Variables: Soil type and pre-existing soil conditions
Key Variables
- MOLF: A fermented solution using molasses, kangkong leaves, eggshells, and lemon juice
- Scallion Yield: The total biomass production measured in grams per plant
- Soil Fertility: Measured by improved nutrient levels, organic matter content, and plant growth
Research Methodology
- Subjects: Scallion plants (Allium fistulosum)
- Setting: Researcher's house with a controlled environment for fermentation and scallion growth
- Experimental Groups:
- Treatment group: Receives MOLF
- Control group: No fertilizer or standard synthetic fertilizer
- Data Collection:
- MOLF Preparation: Fermentation process detailed in the study notes (see below)
- Plant Growth Measurement: Regular monitoring of plant height, growth rate, and final yield
- Data Analysis: Statistical analysis to determine if MOLF has a significant impact on yield
MOLF Preparation
- Ingredients: Molasses, water, kangkong leaves, eggshells, lemon juice
- Fermentation Process:
- Ingredients mixed and fermented for 2 weeks in a warm, dark environment
- pH monitored and adjusted with warm water
- Changes in odor and consistency indicate successful fermentation
Study Notes
- Random Assignment: Used to minimize selection bias and ensure comparability between groups
- Internal Validity: Focus on dependent variables while incorporating mediating and moderating variables
- Location: Philippines to ensure findings are applicable to local farmers
- Sustainability: MOLF aims to minimize negative environmental impacts compared to synthetic fertilizers
- Organic Farming: Focuses on using MOLF as a natural input to promote environmentally friendly practices
