in my class i have to plant and grow grass seeds for 2 weeks. the group who has the highest yeild of grass wins. i need help with this. can someone please tell me the best fertilizer and othere chemicails i should use. we are growing them in class in a inclosed enviorment.
Who is providing the soil and seed? And, what grade are you in?
in 2 weeks fertilizers isnt going to work. to get the highest yield you need good heat under the germination tray, light misting keep the seeds moist but not sopping wet and then air movement to prevent molds while the seed germinate and prevent damping off disease. pre-treating the seeds with a germicide is always a good idea.

Germicide.....good, in theory, but I wouldn't be suggesting the use of any sort of "cides" to someone who might be so young as to not understand the hazards of certain chemicals.

best suggestion I have is use annual or perennial rye seed, which have 3-6 day germination periods. Other grasses are slower, such as bermuda which germinates in 14-21 days or fescue in 7-12 days and would not grow much in the length of time of your experiment. Ryegrasses also grow faster than most other turf type grasses.
Create a mini greenhouse. Put some regular potting soil in a plastic cup. Add some water, enough to just make the soil damp. If you feel you need a bit of fertilizer, just the weakest dose of miracle gro you can.
Put the seeds in, add another shallow layer of soil (about 1/4 inch.) Then cover the cup with saran wrap. Poke a few holes in it the plastic with a pencil. Then put near a light source, but not on a window sill.
Instant speedy grow.

And, when the project's done, give it to someone who's got an indoor cat. They love to eat grass.

Which species? Fertilization and "other chemicals" won't do much (other than the possible use of KNO3 to shorten dormancy in some species). Your best bet is fairly rigid environmental controls of light and temperature. For many species of grasses, different day and night temperatures are better.
LOL - I've done that! I once spilled a huge bag of that stuff all over my porch. I was working, and ignored it - then forgot it. By the time I went back out four days later, my unknowingly leaky hose and spilled birdseed had given me a green furry porch!
Ahh - they joys of your first apartment.
If you can use *any* species of grass, I'd suggest the largest seeds you can find of corn, Zea mays, and a soil temp of 65-8ooF.
use raw seed, not coated with anything such as a fertiliser or fungicide which slows down the germination rate.
