The Trophobiosis Theory based on agriculture systemic approach: eficiency of organicagriculture practices

Abstract

In agriculture, the systemic focus is more and more necessary, because of the crescent complexity of organized systems managed by man and the urgency of the sustainability concept. The systemic approach looks for understanding the interaction of factors and the ambient complexity, with astudy of the total development of systems, instead of concentrating in isolated parts. The physiologic vegetal resistance, that has one mechanism in Trophobiosis, contemplates the systemic vision, considering that the environment of an individual crop plant consists of many factors that interact among  themselves and that the sustainable management of the agro-ecosystem requires the knowledge of the environment complexity and of how the factors can be managed. According to the Trophobiosis Theory, every vegetal organism is vulnerable to the pest infestation and illness when excess of free amino acids and glycosides reductor species are present in the metabolic system. This study, based on agroecological principles and methodology, tries to determine which organic agricultural practice can be more efficient in the contribution to the trophobiotic equilibrium and how the trophobiosis is directly related tothe crops agro ecological management, helping out to the physiological vegetal resistance and distinguishing itself as an agro-ecosystem mechanism of sustainability
