摘要：This paper presents the results of a study on sustainability of alternative corn farming systems. The aim of this study is to select indicators for sustainability analysis, and to set up a methodological path. While talking about sustainable agriculture is increasing in the academic, technical, extension, farmers association communities, it is still difficult to determine if and how much an agricultural system is really sustainable. It is really difficult to determine at what point does philosophy end and science begins. Vernon W. Ruttan, in closing his paper “Sustainable Growth in Agricultural Production: Poetry, Policy and Science”, asserts: <>. (V.W.Ruttan, 1991). Now, after seven years, the situation is not very much changed, but subsidies that governments, particularly in the EU, are providing to the farmers for lower input agriculture, call for appropriate methodologies to measure sustainability of agricultural production.
