The idea of designing a multispecies agroecosystem as a structural and functional mimic of natural ecosystems is appealing, because it offers a simple integrated principle for working towards sustainable agriculture. The hypothesis that diversity is associated with higher productivity is not new, as early as 1859 Charles Darwin asserted that it has been experimentally proved that if a plot of ground be sown with several distinct genera of grasses, a greater number of plants and greaters weight of dry herbage can be raised in the latter than in the former. The search for new models for agriculture is particularly attactive where modern agriculture that completely dependent on fossil energy and chemical inputs is unaffordable, unsustainable or no longer acceptable to our quality of life (lefroy at al.,1999). But natural systems are much more complex than any form of agriculture used today, where the trend is still one of reducing complexity.
