I have added a plane with a color-ramp as texture and added a particle system (grass) as seen below.
what I need to do is make the grass grow from the green area, not the blue area and not from faces or vertex
Is there a way to do that?
thanks.

You need to bake a copy of the node in a grayscale (where the value correspondes to the density of your grass), and use it in your particles' textures with the option to influence the density.
it's not possible your only options for growing are by using; vertex weights, textures, grooming(particle edit) or by simply by object.
