There are really two poles when it comes to food plots. On one end of the spectrum you have folks working at scale that are trying to do QDM. With this the primary objective is feeding deer and it requires significant scale to have measurable results. At the end of the spectrum you have folks planting a couple small plots. Here to objective is attraction and perhaps to improve hunting opportunities not feed deer.
I did traditional tillage when I first started and had great food plots, but they were very high input. When I switched to min-till, it took a while to get the hang of it. Seeding rates, timing, weed control, all come into play. Once I got the hang of min-till, I'd say the attractiveness of the plots is just as good as I got with traditional tillage with lower inputs and less work.
I would agree that minimizing tillage does have a learning curve and requires a more intimate knowledge of your soils and conditions.
