Cacao orchard -Erythrina poeppigiana tree for Nitrogen fixing and shade, Wind?

[professor]

Hello,

I am planning on planting some Erythrina poeppigiana to help with Nitrogen fixing on my Cacao and use the tree as an upper shade permanent orchard tree and to help as a wind break.  My cacao are spaced at 3m and I have read to plant this tree at 12m spacing if you are not planning on cutting it back each year.  My questions is does anyone have experience with how wind tolerant this tree is, and what percentage of shade it produces?  Thanks
