As a player over a period of in-game years, what magic items and spells would allow me to create as much food as possible for a large town (~1000 people) assuming most of them are farmers/could help, and space is not a concern. The town is being created with this goal in mind, so this can be factored in (eg. circular fields for the effects of [*plant growth*](https://www.dndbeyond.com/spells/plant-growth)).

This is not including spells that are very small individual buffs (*Haste*, [*Enlarge/Reduce*](https://www.dndbeyond.com/spells/enlarge-reduce), etc). They do not need to be explicit about food/farming, something like the [Decanter of Endless Water](https://www.dndbeyond.com/magic-items/decanter-of-endless-water) would also work.
Lower magic is preferred (1st-5th level spells), but higher-level options are also good to know.

This question has a broader application than [this related question](https://rpg.stackexchange.com/questions/180555/does-plant-growths-8-hour-effect-stack) that is only about the plant growth spell's applicability.
