I have a project in my grade 11 biology class to design a controlled experiment showing how some factor affects plant growth, specifically radishes. I have decided to add urea as a nitrogen fertilizer to one group and do nothing to the other leaving all other factors the same between the two groups.
I have found this pdf: http://www.fspublishers.org/ijab/past-issues/IJABVOL_6_NO_3/19.pdf
This experimentation shows a significant increase in plant height, root length, and number of leaves when the plants were enriched with urea. The concentrations of urea are given.
My experiment, however, will be on a much smaller scale. I am growing 24 plants, each in its own individual compartment, around 4cm long by 4cm wide by 5cm deep. I need to know if I can use the same concentration of urea as was used in the study I linked to.
