Managing cropping patterns agricultural crops of Three Counties of Mazandarn province of Iran

ABSTRACT: Augmenting or limiting cultivation of agricultural crops in different areas shall be done with consideration of resources constraints and availability of fertile agricultural land. This makes design of multi-regional model of cultivation of crop products necessary. This model should be pervasive and integrated in one hand and separable in accordance to the region. Moreover this model shall be able to recognize the resources possessed in common between areas of region as well uncommon resources between areas. Separating a model based on area will increase modelʹs precision for each area and superimposing these area models will results in trans-regional attitude. The result of this research shows that optimum cropping pattern will increase the total profit of regions, Babol, Babolsar, Qaemshahr, according to their show, 6.8%, 8.9%, 5.6%. Furthermore, use of multiregional model will increase the profit 8.5% to this condition and 1.4% to whole of regional models. The execution of this models result in reality is possible with optimal allocation of inputs.
