I'm trying to help some friends in S America.&nbsp; They want to polycrop and grow food along with jatropha to use for biofuels for their farm.&nbsp; Jatropha is toxic (berries, maybe other parts?), and it is a drylands plant - I would like any tips that anybody knows of as far as polycropping with jatropha - downsides?&nbsp; Any successful actions?&nbsp; What food crops might go best with jatropha? &nbsp; Is there a better drylands plant to use for biofuels?&nbsp;&nbsp; Etc.<br><br>Thanks, Cory<br><p>&#32;
