first of all, you have to check the ip subnet:
Are you using the same or not?
Because you can have the same ip address/subnet on
subinterfaces.
For the same subnet (multipoint hub-spokes) I'd say you must
"reach" no ip split-horizon for both RIP & EIGRP

Thread-topic: IP split-horizon
Depends on you setup and what you are trying to a complish. If you need the
hub
router to announce routes it learns through the same interface it's
advertising
that route, then yes you need to disable it.
The best way to figure this is out in a lab is to test it out. Have a hub and
spoke setup: one setup uses multiple PTP ints, thus no need for split
horizons;
the second uses multipoint setup with on network. You will find that the
routes that the hub learns from the remote routers will not be learned by all
the remote routers because of split horizons/poizon reverse etc. If you
disable
split horizons then you will see the routers learn all routes adv by the hub.

Hello,
But if they are in diferent sub-interfaces, do I need to disable
split-horizont
?
