Does anyone know where i can find tutorials on 3d grass rendering (no vertex/pixel shaders)!
If you have any ideas fell free to share them.

well.. I don't know a tutorial but can tell you how I would do this (or rather, already implemented it althoug up to now, it isn't used).
You probably know of the technique to render trees as textured quads where parts of the quads are invisible.. like on my screenshots:
Below the tress you can see something like grass which is basically done the same, I know that it doesn't look very realistic on these screenshots but that's more an issue of modelling and design and density than of the technique itself.
You can also move the "upper" vertices of the gras quads a little bit from left to right, making the grass wave in the wind.
