It's hard to make reasonable speculations about agriculture _in
isolation_, since developmnets in other areas can be vitally important.
For ex, agriculture today is similar in principle to what it was
thousands of years ago, but things like mechanization and the Haber
process have transformed it in detail.
Agriculture might remain recognizably about specific plants, for ex,
but genetic engineering could transform the plants. A TL13 field might
be be very dark green, the result of more efficient photosynthetic
processes. Or what are not perennials might become annuals (a wheat
tree?). The actual farming might be performed by microbots (my gut
hunch is that science fiction has overestimated the importance of
nanobots in the future, and underestimated the importance of merely
very small (rat to insect sized) machines). Future superplants might
suppress weed growth near them, for ex, by their own biochemistry, too.
(Of course the weeds would adapt themselves over time, too.)
Or perhaps the old SF standby of the yeast-based cusine might be
workable. That strikes me as a better bet than 'assemblers' making the
food from raw elements, to be honest. I have very little faith in
Drexler's visions.
Agriculture is energy-intense in both the sense of mechanization and
growth. A remarkab le amount of solar energy is required by plants,
supplying it artificially would require large power sources, but plants
might be made more efficient. Alternatively or in tandem, one might
grow food in greenhouses simple to maximize control of externals like
temperature and humidity and to minimize pests. It's not economic
today, it might become so.
As other posters have observed, meat might conceivably (though far from
certainly) be 'grown' in factory-like environments, too.
But two factors to keep in mind is that intensive agriculture today is
highly dependent on convenient, concentrated energy supplies (i.e.
petroleum). That's how we've gone from a society in which ~50% of the
population work in direct agriculture to a situation in whcih a tiny
fraction grows more food than the 50% once did. We replaced large
numbers of poeple with machines and chemicals.
A TL13 agricultural system would probably be intimately linked to
external technologies, it would be far more than just a matter of the
food itself.
