Let me guess this is the question for today?
I actually managed to get 5-0-4 and reused it. I just plant 8 wheat around a double-crop. If you scan it and it says Wheat it's the vanilla-one with 1-1-1. So now I got a 3-1-2 and replaced one of the 1-1-1 with it. Cropnalyzer also tells me it's 3-1-2 by rightclicking the crops. I startet to replace all 1-1-1 wheat with better ones. I'm now at 8 wheat which are all above 1-1-1 and managed to get a 4-3-5 in the middle, which I used to replace a 2-2-1. I hope to eventually reach values above 10 soon and actually this 8 wheat-crops provide enough wheat to feed me (since I don't do that much I don't get that exhausted).
Oh... and I got some Pumpkins in the process... yeah 8 Wheat -> Pumpkins happened two times out of about 20. I quite often get 0-0-0 Wheat^^. I kept some of them to compare a later elite-crop with the 0-0-0-loser-crop
