Absolutely -- there are lots of options that will enable you to store and save food through all seasons, or even grow produce yearround. Greenhouses can extend the growing season, with heated greenhouses even able to grow out of season vegetables in the bitter cold of winter. This is a great way to provide even nutrition yearround, and can make subsistence agriculture much easier for you and your family.
Each individual you intend to feed should be allocated between 5 and 20 fully grown crops per year. This depends on how much of the produce you intend to use, and what kind of yield each plant produces. If growing food all year long doesn't sound ideal, it may be better to save and preserve your crops. Veggies and fruits can be canned, dried, frozen, or any combination thereof.
