In the banana area located in the alluvial plain of the Motatan river, in Trujillo state, Venezuela, are four enterprises that produce banana with the aim of exporting them, which presented a reduction in quality and number of bunch by hectare, with the question about the duration of the useful life of the banana crop in the area, so it was determined the economical period, measured in years, from the crop to the moment that was necessary to proceed to the removal of the banana plantations, determining the equilibrium point expressed in exportation boxes, and a practical model that allows that banana producers of the area that is being studied, to take the decision of renewing. The area was visited from may 1998 to may 1999, in order to obtain all the economical and production information. The population is of 1000 Has. The results showed a reduction in the bunches number by hectare when years have passed, being necessary to renew at 3 ± 1 years after the sow. The equilibrium point was of 2533 and 3109 boxes by hectare, without and with financing respectively. The prediction equation for the collect variable by hectare was: Y: Emb/ha 3131.671182 247.635691 x age. 60% of cost to produce a banana box corresponds to the manpower.
