Name: UNIV6020 Assignment Description: This project aims at exploring the impact of varying amounts of vermicompost and urea fertilizer on the vegetative development of corn (Zea mays L.). The research design is a two-factor factorial experiment design where the application of vermicompost is at five levels and urea fertilizer is at four levels in three replications giving 60 units of the experiment. The parameters of growth such as stem height, stem diameter, length of leaves, width of leaves, and the number of leaves were measured at 64-65 days after planting. All the data would be stored in one, structured dataset at the level of experimental-units to facilitate transparent data management, statistical analysis, and reproducibility with the help of Excel, R, or SPSS.
