I forgot about a book that I had on my shelf called 'The Reference Manual of Woody Plant Propagation.' Copyright 1987.  Lots of people have great methods on this forum but I thought I would post what it said about Ficus Carica.

"In several tests 1000 ppm IBA-5 second dip provided optimum.  February, terminal bud removed, 50 ppm lanolin paste (control) rooted 50% with an average of 4 roots; 770 ppm 1AA-lanolin paste rooted 100% with 23 roots per cutting in 28 days.  March, untreated rooted 80% with an average of 13 roots per cutting.  200 ppm IBA-24 hour soak rooted 100% with 61 roots per cutting.  Girdling 30 days before taking cuttings increased rooting from 55 to 100% and hastened rooting to 28 days versus 90 days.  In a brazilian study, 10" long cuttings rooted 97% and gave best shoot and root development.  Summer wood should root but no literature was found."  pp 124-125

 Personally I've never seen 61 roots per cutting so I do find this interesting.

Remp,

Interesting study, but the published results seem to lack definite start and end days of evaluation (i.e. cuttings of Abc were treated with x, xx or xxx and after 28 days root development found to be ...). Maybe the full report contains that info without jumping around. btw, here is what 61 roots per cutting looks like ;-) :

Yeah the study is not comprehensive because it is part of a huge manual that covers quite a bit. I thought it might be of interest to some members though.
Impressive roots on your plants Ruben!
Do you root your cuttings in plugs or transfer them to the plugs after you have gotten roots?
The cuttings I received from you continue to thrive.

From Remp's post:  'Girdling 30 days before taking cuttings increased rooting from 55 to 100% and hastened rooting to 28 days versus 90 days.' That's pretty impressive.  My questions are how was this done and was IAA/IBA hormone also used?  Was it a cutting or an airlayer?

Eric,

Back then I was using what was available (water bottles or drink mix containers) and 100% Vermiculite. That's why I would rinse the roots off.

John,
Sorry that's everything that was published in that book.  I copied it word for word. Air layering was never mentioned though.
