Why would a plant grow faster without fertilizer then a plant with fertilizer?

TOO  MUCH  FERTILIZER!!!!

There is a reason why plants only grow so high in nature.  They have to be able to still pump nutrients from the roots to the farthest limb.\n\nBesides, you would be providing a home for rats.

Because light is needed for photosynthesis which makes energy..since the seeds have no leaves and hence no photosyntheisis they get around by having enough energy material provided within the seed to allow for growth until plant is above ground and has the leaves needed for photosynthesis

They convert inorganic material to organic ones to make the soil fartile. This is done due to their living and it also helps in living the plants... both way benefecial :)

Plants which reproduce without seeds appeared first in the history of the Earth.  Plants with seeds appeared much later.

Living things have growth and metabolic activities\nNon living does not have any growth.\n\nliving ex-> man,plants,fish,etc.\nnon living ->building,stone,car,etc.

if a plant is in a windy area, evaporation happens faster. Or in not too bright of sun, photosynthesis happens faster.  Also, if it's well watered, the roots suck more in and push it through the plant.  \n\nThis probably won't help at all, since I have no idea of what you're really talking about, but someone once told me that they liked nothing more than attempted BS.

If you were a plant you don't want to start growing (from a seed) right next to the parent plant as competition for sunlight and carbon dioxide would occur. Therefore, you want seeds to be dispersed by wind, water etc.

Hmm, you are in luck.  I am a biologist/chemist with a little ecology and botany knowledge and I might be able to help you out here.  But in the future, procrastination is not the answer.  Trust me, I know.\n\nAnywho, on with your project.  And, kudos to your teach.  He is getting you ready for college.  Lets see, you are wanting to germinate seeds.  It would be feasable to choose seeds with very quick germination times as probably you don't have a very long time to perform this experiment.  Some grasses will germinate in as little as 7 days.  With a little research, you can find your own seeds to use.  Next, you are going to have to decide what treatments you want to apply to each group.  And by each group, you need to have more than one "cup" of seeds, more like 4 or 5.  That is for replication.  By treatments, you could use things like adding different types of fertalizer in each group.  Use fertalizers that differ in the amount of phosphourus, nitrogen, and potassium (3 primary nutrients required by plants.)  Then, with multiple groups recieving the same kinds of fertalizer, vary the amount of sunlight (preferably artificial, like an incandesant lamp) and amount of water given.  What you will end up with is something like this:\n\nfertalizer A - 15 cups; each cup gets 1 tb of fertalizer\n      Cups 1-5 get 10mL of water and 12 hrs of "sunlight" daily\n      Cups 6-10 get 10mL of water and no "sunlight" daily\n      Cups 11-15 get no water and 12 hrs of "sunlight" daily\nRepeat this for say, 3 or 4 different types of fertalizer over a 10 to 15 day period.  Also, have 15 cups that follow the above procedure but get NO fertalizer.  After the 10 to 15 days, compare growth of the plants by measuring (probably in mm) the amount of growth produced.  \n\nBy performing a little research of your own and whatever plant seed you decide to use, you can base your hypothesis on how each fertalizer "should" affect your seeds and how much they "should" grow.\n\nFor example, lets say nitrogen is the main nutrient needed by grass.  Any of the fertalizers used that are low in nitrogen would not grow as much as the ones that get the nitrogen.  And those that do get the nitrogen, the ones that get water and sun will grow more than the others that get only sun or only water.  So, your hypothesis would be something like this:  The seeds that recieve adequate amounts of light, water, and nitrogen will have more growth after x amount of days than the other plants.  Then, you perform the experiment and see what you get.  \n\nGood luck on your experiment and if you remember, let me know what your teach thinks and what grade you get!

there are tons of factors affecting plant growth. one of them is the kind of soil for the plant to grow. some plants need a specific type of soil in order to grow properly. another factor is the sunlight and food it gets. it needs the propwer nourishment for the palnt to fluorish. next is the nutrients that a plant need. some may need medicines to help them grow better.

If I'm not wrong, the two are directly proportional - the more the nutrients in the soil, the more they would favour plant growth by the synthesis of proteins and hence better and greater yield. \nBut I think this would go on till a certain point ( it might be the saturation point or something). I mean, if your bestow the soil wholly with more minerals and nutrients than the plants need, it won't give you more yield, because then the yield rate will be limited by other factors such as light and carbon dioxide. If you then increase the latter two factors, then the yield will increase again.\n\n[Again, I'm not sure about this....someone please correct me if I'm wrong!!]\n\nEDIT: Ah, there you go.....Fred gave a more thorough explanation.

Marigolds grow like weeds and dont need fertilizer ,\nas for the sand , mixed with the soil/potting mix will improve the drainage and allows the roots to breathe better .\nThrive is slow release fertilizer so use sparingly .\nGood luck and keep up the green thumb !!

I'm going to assume you are talking about plants. It depends. More transpiration means more water flows through plants, so of course more nutrients will enter the plant tissue. However, the amount that is actually absorbed for use by the plant is controlled by the plant cells.... excess minerals are usually stored.

There have been several experiments to see if this was the case.  The first one stated that classical music helped plants grow much better then other forms of music.  However, more experiments since then have shown that there is no link to plant growth.

Plants make vitamins . They make what they need. Vitamins A and D are fat soluble. They will not be absorbed by the plants. They will sit there in the soil.If there was enough to coat the roots, it could have an ill effect.\n\nThe fast growing seeds that are generally used are radish seeds.

The plants basically evolved over time. The plants that could survive on land did and had plenty of nutriens and no competion. So they had to devolp ways of carrying nutrients to the plant since they could no longer use water. They then devolped xelom and phyleom (possibly mispelled) which are similiar like the blood vessels in our body(no blood in plants). Main point is that they had to overcome not using water to transport nutrients inside of them. The flower is mainly to do with spreading the seeds. It devolped so that seeds would find a way to less populated areas and have less competion. Hope this helped.

many plants tend to be healtheir and grow faster and produce more using hydroponic means.\n\nHowever not all plants can be adapted to such means.\n\nSee the sources below for more information.
