Answer:
One example of quantitative research in agriculture and fisheries is a study that investigates the relationship between fertilizer application and crop yield in a particular crop. The study could involve the following steps:
- Select a specific crop, such as rice or maize, and a specific fertilizer, such as nitrogen or phosphorus.
- Identify a suitable study area, such as a farm or a research station, where the crop is grown.
- Design a randomized controlled trial (RCT) to test the effect of the fertilizer on crop yield. The RCT could involve dividing the study area into plots and randomly assigning the fertilizer treatment to each plot.
- Measure the crop yield in each plot after the harvest and record the data.
- Analyze the data using statistical methods, such as regression analysis, to determine the effect of the fertilizer on crop yield. The analysis could also include controlling for other factors that may affect crop yield, such as soil type, weather conditions, and pest infestations.
- Draw conclusions from the analysis and make recommendations for fertilizer application practices in the crop of interest.
The results of this study could be used to inform agricultural policy and practice, particularly in the use of fertilizers to increase crop yield and improve food security.
