Onion cultivation

Dear All,

I am growing onions in 2.5 acres and they are now 3 months old. The land is little slant and onions at higher elevation are very small(look like they are just one month old or even less) and those in the down where water flows and accumulates are bigger in size.

Question: What to do with the onions which are very small at the elevation? Are they going to be waste or is there any way to use them?

Thanks in advance
