Consider that a safe take off in a twin requires reaching Vmc before rotation, Vmc being the minimum speed at which the plane is controllable with one engine out (and with critical engine running).
Vmc is usually significantly higher than rotation speed you use in a single engine plane with comparable wing loading and stalling speed. The same is true for landing, in the event of a go-around. If the number is unavailable, you can use a common sense approach: rotate the plane no slower than 1.3 times the stalling speed, and do the same for flaring on landing. All of this agrees well with mattag08 suggestions. Landing and taking off in a multiengine are always critical and require extra cautions.
