Suivi et analyses des performances de systèmes de culture économes en produits phytosanitaires et en intrants en vergers de pêche-nectarine et pommiers

Abstract : After 8 years of experimentation, the economical orchards of the Ecopêche project have met the objectives in terms of reduction of inputs and phytosanitary products were maintained while ensuring a satisfactory level of yield. The knowledge acquired throughout the project has made it possible to improve decision-making and combinations of action levers to be implemented. However, there are reductions in efficiency for ECO systems. The densification of this system shows that it is possible to compensate these declines by increasing the number of trees per hectare. It is still difficult to conclude on the value of the use of peppermint combined with the reduction of nitrogen fertilisers. PLS-PM analysis appears to show some effectiveness of decision rules and seems to offer new perspectives for the Ecopêche project and future projects related to system experimentation within the systems studied. The use of this kind of analysis opens up new perspectives for the analysis of complex experimental data with the aim of improving our understanding of the relationships between variables and the set of mechanisms and interactions present within systems studied.
