These are timelines that have as their POD(s) alternate developments in agriculture, focusing on how said developments (e. g. alternate domestifications, etc.) influence the later history of the society or culture they emerge in. While the PODs for these timelines usually go back deep into human prehistory, it is not an absolute constant. For instance, an agricultural timeline can also involve a Native American ethnicity developing an agricultural practice that they never quite got the hang of in OTL.
