Doug,
   
  That may be a possibility.  The problem is finding the right grass.  Right now, 
  most of the fields ploughed by the previous owner are invested by crab grass.  
  It goes dormant during the winter and starts growing in the spring.  It is hard 
  to imaging anything that could compete with it during the summer.

  If you can find something like a grass which

1. goes completely dormant during the dry season yet shades the ground and
protects it from wind, and

2. is hsopitable to being interplanted with your crop in your wet season

you might have some success.
