How much fertilizer should I give a radish plant?

Hi,
so i have to do a science project and i am doing”How much fertilizer do you need to grow a healthy plant?”
so i am doing 3 plants and giving them different amounts of fertilizers.
then i measure on how much they grow.
and i am using a spray fertilizer
but i odn’t know what would be the “right” amount of fertilizer to give so i can do one lower and higher.
how many seconds should i give my plant to fertile?

There is no “right” amount for fertilizer. The correct amount will depend on the fertility of the soil you’re using.

I would do this:

1 radish with the recommended amount of fertilizer that is listed on the package. If you’re growing indoors, use the amount and frequency listed for “houseplants.”
1 radish with 1/2 the recommended amount of fertilizer that is listed on the package.
1 radish with no fertilizer.

Make sure you use the same soil from the same source (potting soil from a bag would be best). The unfertilized radish is your control. Make sure they get the same amount of light, heat, and water. If you want to do one “higher” I would use a fourth radish with twice the recommended amount of fertilizer.

However, if your question is “How much fertilizer do you need to grow a healthy plant?” then you probably want LESS fertilizer rather than MORE, because you’re trying to figure out exactly how much you can get away with and still have a healthy plant. Make sense?
