En este trabajo se diferencian patrones de cultivo en una muestra de quince huertos mediante clasificación multivariable aplicada a registros mensuales del área relativa ocupada por los cultivos en cada huerto, como un aporte metodológico al estudio de sistemas agrícolas complejos. Los resultados revelan la existencia de un patrón de cultivos de primavera y otro de verano, diferenciados principalmente por cambios en especies ornamentales cultivadas. Asimismo, se encontró que los hortelanos que prefieren herbáceas de ciclo corto cultivan superficies menores, tienen un promedio de edad más bajo y manejan menos especies que aquellos que cultivan herbáceas bienales y perennes.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The small horticultural systems of Mexquitic, San Luis Potosí, are intensive and complex with respect to the spacial and temporal arrangements of their irrigated crops. In the present study, crop patterns are differentiated in a sample of fifteen gardens by means of multivariate classification applied to monthly records of the relative area occupied by the crops in each garden, as a methodological contribution to the study of complex agricultural systems. Results show the existence of a spring crop pattern and another of summer, differentiated mainly by changes in the ornamental species that are cultivated. In addition, it was found that the growers that prefer short cycle herbaceous species, cultivate smaller surfaces, have a lower average age and manage fewer species than those who cultivate biennial and perennial species.]]></p></abstract>
