Sprinkler wire can generally be buried directly in the ground without conduit and you don't necessarily need to dig it below grade. A shallow burial is fine.
Can I wire two sprinkler zones together?
Running multiple zones at once is usually not possible due water-pressure and flow limitations at residential properties. As with any standard irrigation controller, you can wire multiple solenoids/valves to the same zone output if you want.
