Yes, different layouts of plants in the landscape have different watering requirements. For example, lawns, shrubs, hanging baskets and borders all require a different amount of water.
Also, the equipment that is being used to water these areas operates at various water pressures and applies water at several rates. Having separated zones will allow these areas to be watered most effectively and economically.
Zoning is necessary when there is a limited size of water source because there we can get enough time to refill the tank as per the requirement.
