Dear Jesse,

For the indigenous sites (and crops) of domestication in South Asia, I recommend the relevant works of Dorian Fuller, an archaeobotanist at University College London.

For a fairly recent overview of archaeological evidence for agriculture in the early historic period, see F. R. Allchin's The Archaeology of Early Historic South Asia (1995).

For Sanskrit sources in particular, the Hungarian scholar Gyula Wojtilla has focused on agriculture for decades, ranging from Vedic to kṛṣiśāstra. Fortunately, a good deal of his works are in English, including his History of Kṛṣiśāstra (2006) and his edition of the Kāśyapīyakṛṣisūkti (2010).

I am currently finishing up my dissertation on agriculture, more specifically on the interaction of agriculture and religion in Sanskrit, and so I should have a fairly thorough bibliography “completed” in a few months. I would be happy to correspond further to isolate works that might meet your interests more specifically. Obviously what I've given above are just general starting points.

Best,

Michael (Mike) B. Jones
