Aspectos poblacionales y productivos de los ecocultivos de maguey en el norte de Zacatecas, México

Abstract

Populations and productive aspects of the maguey’s ecocrops in the northern region of the state of Zacatecas, México. A research was conducted in order to character ize the development and the population dynamics of ecocrop of pulque agave. and to evaluate the productivity of hidromel of ecocrop of A. atrovierens and A. salmiana. On agaves established in the experimental camp Noria de Guadalupe, belonging to UAAAN, it was accomplished a sampling, an estimation of the population dynamics and of popula tion exchange rate. The result was an established yield of 92 percent, and a high degree of permanency and resistance to the environment during nine years. The production of shoots per plant corresponds to ten, the population exchange rate to 1.02. Of the total of the population only 2.17 percent is the portion with attributes considered adequate for cropping. On twelve agave plants was measured the hidromel production and was statis tically analyzed considering as factors kind, time, and quantity of the take of the sample of the day. The hidromel production was of 112.16 in a period of 51 days, in average, being the spring one more productive and greater days: quantity of hidromel produced in comparison with the one made in autumn. Of A. atrovierens and A. salmiana was found a difference in production favoring the second one. The morning takes turned out to be greater than the ones made in the afternoon. So it is concluded that the ecocrop of agave should be recommended for its success in population development, as well as for consid ering it a source for sustainable production of hidromel in the semiarid. Region.
