Not going to be anywhere near enough food for one person unless you have more land available for yourself than people in a city or even most modern suburban developments are likely to have.
i did a study on area needed for food production a while ago, and IIRC
per person, about 1000 m² are needed to feed them. depends a bit on where you live though
fertile land produces around 3.5 t of grains /ha on average. with modern technology, the peak is 7.5 t/ha
by far the most area is needed to grow calorie-heavy foods. like, you could get far with 30 m² for yourself if you only plant vegetables and buy the grains at the supermarket
grains are really cheap, compared to vegetables. that’s because vegetables are labor-intensive (difficult to automate because they’re often fragile and sensitive) while grains can be automated on ultra-large-scale farms with farming machines, so they’re really cheap.

Note: 1 t = 1000 kg, grains = cereals
