Mycorrhizal fungi aren't a fertilizer by itself, though, might moderatly improve the nutrients a plant can absorb. Since tomatoes have different priorization in needs for growing, flowering and fruiting, the answer might not be as simple. On top of that, it's depending on what type of method on planting is chosen. If the answer (and according to the myco-question I guess it is), is soil, then again, nutrients of the soil should also be of concern, as salinity, humidity and so on...

But after all, guano is quite common among fertilizers used for solanum lycopersicum (and capsicum).

I agree with Nico Jakel. Mycorrhizal fungi help to plants, specially in absorbing phosphate from the soil. Thus, it seems that they help to root generation, early flowering and also, drought tolerance.

I know that the mycorrhyza fungi can't help alone for saving plants in many features. We must recognize that some factors act an important key in plants as like water. Anyway, act as stregthen. These are whole i know. I use mycorrhyza alone in pear plants to recognize drought tolerance, but it didn't really work.

These fungi act better at laboratory conditions, but haven't farm conditions more effective.
