Is it correct to say in a poem or a rap song, "the fields are ripe the wheat is white" Thanks very much.
The fields are sown, and the wheat is grown
Fields cannot be ripe though one can say X is ripe for Y.
Ripe and white are slant rhymes: they have the same internal vowel sound.
Sown and grown are ends rhymes, which might be better in rap.
The fields are ripe to my ear just sounds ignorant, sorry. The wheat is ripe does not sound ignorant.
