Effect of fertilizer on plant growthFeatured science projectScience project video

Observation

It is observed that the plants in group C which were watered at the recommended concentration of fertilizer had the fastest growth in 10 days. The plants in groups A and E which were watered with fertilizers at concentrations that were either too low or too high, had the slowest growth in the 10 days.

The table below records the radish plants' average height (in mm) measured after 10 days.
