"Project Black Harvest" was a secret Adascorp project involving the research of exogorths. Director Artonian Dobonold and lead scientist Gorman Vandrayk were known to work for it.
As confirmed by John Jackson Miller, the name "Black Harvest" is a reference to Blue Harvest, the codename for Star Wars: Episode VI Return of the Jedi.
Curiously, in the Knights of the Old Republic Campaign Guide it is referred to as "Operation Dark Harvest".
