Conclusion

Unlike the majority of historical empires, the Tawantinsuyu had a north-south axis (Turchin et.al. 2006), so that all the seeds need to be adapted to the photoperiod of latitude, whose annual amplitude is about an hour in the Andes.

Urban maize cultivation on a sort of scientific or protocientific breeding strategy at the start of Tawantinsuyu (see Tab. 3) under the conditions of ecological frontiers explain, according to recent theories (D'Altroy, Earle 1985), the specific strategies of financing of the empire:

The Indian corn (zea mays) was a resource to the governmental coffers. The Incas send their instructors to teach experimental farms to peasants.

Today that kind of educational services are provided by the Association of ecological farmers of Austria (Bio Austria) through the TICS in the form of VideoBridge as a popular ‘’Ciberconferencia’’ in the Global Village (‘’aldea global popular’’) Kirchbach, Styria, located in the semipheriphery of Austria. The Authors visited it between 19 and 21 April 2008.

This is a topic of the forthcoming paper by Liliana Muñoz Villar. Within Andean peasant culture there are still ‘’yuyayñiyuq’’ or ‘’yachayñiyuq’’ as specialists of "cultural memory" (Assmann 2005).

This may have been a survival in form of a social function or institution that survived the conquest of the Incas. Some farmers already know that without love there is no life, so it may pay searching the mythological roots of the drama Ollantay within the Andean cultural memory as the Apu Ollantay problem was the first South American revolutionary, a topic that requires a special work.
