Concept of sustainable agriculture is a relatively new response to the decreasing quality of the base natural resource which is dependent on modern agriculture and sustains able development of any country is dependent on the sustainability of its agricultural systems. Therefore, this study is performed to investigate the subjective indices of sustainable agriculture in rural areas of Gorgan city. This research was carried out applying a survey method that used the data collected through field study. The research population consisted of rural households in all villages of Gorgan city from which 261 people were selected using Cochran formula and stratified sampling and the needed information was collected through a valid question naire as them a in tool. The results of the statistical analysis in SPSS software showed that the 12.5% of indices was fully sustainable, 19.5% was in sustainable group, 45.25% was in somewhat sustainable group, 5.20% was in the unsustainable group and 5.17% was in the very unsustain able group<\div>

one of the ways to increase agricultural production is to increase the acreage. The increase of acreage regardless of production limiting factors causes non–optimal use of available resources and therefore will lead to cropping program failure. According the role and importance of crop units management, using mathematical models have significant role in determining optimal cropping pattern. Hence, in this study, use of fuzzy linear programming model to determine the optimal model in Boroujerd city was considered. For this purpose, to maximize program efficiency regarding the existing systematic limits for different products in the region, different values of λ was considered. Data of this study was related to 2010–2011. The results showed value of for the optimum cropping pattern. The current planting pattern with the cultivation patterns of wheat, sugar beet and fodder corn acreage compared with the available situation should be increased and it should be reduced for barley acreage and have no significant change for broad beans.<\div>
