Sugarcane does the best job. It grows very fast and yields alot more.
Thank you 
It should be a 11x11 centered on the harvester. The cropmatron is a 9x9.
This along with some buildcraft pipes gives more sugarcane than you can pump into a compacting recycler. I use some of it on the side for biogas.
I have found that you need a surprisingly small amount of biochaff to run a nice setup.
Nice. Thanks for showing me that. I had a vague idea about sugar and scrap, but I'll use this very thing, it's great. Now with my new Nuclear Biogas 5x5 I'll have enough scrap to make serious UU liquid
You can also make CropBreeding to increase the amount of yeld and groth a little bit.
The max amount it can get on each number is by the way 31. (To get it that high take a while but when you have it you get so much that nothing can keep up harvesting it).
