In agriculture, time work is not so well defined. It appears first in confusion with others times : domestic, per- sonnal... But, it's precisely this whole, its complementarities and coherences, which offer an original interest. Time, if it's constraint, leads to various purposes.

Therefore, links and coherence between their home and professionnal activities, and the potentialities it leads in matter of productivity, asked to account farmers time work.
