Abstract

Accurate production planning is required for crop yield to be accurately estimated. Therefore we will be able to gain a forecast at the macro level by determining market demand for developing or mitigating products or other planning issues related to production systems. In order to study optimal cropping patterns in East Azerbaijan Province, potential productivity for wheat, barley, chickpea and safflower were studied based on an analysis of supply and demand sources. The AEZ model was used to estimate the potential of yield, as proposed by FAO. In this way, it is assumed that the cultivars enjoy high efficiency and that limitations of water and soil, pests and diseases do not exist. To form data layers, IDW and kriging methods were used. Zonation of POTENTIAL PRODUCTION was conducted using the overlapping layers in the GIS. Model validation was conducted using RMSE and the Willmott index of agreement. The estimated values were more than the actual quantities for wheat and barley (r2=0.71) but, for chickpea and safflower, they were slightly lower than the actual data (r2@0.50). The production capacity was acceptable for all four crops in the study region. Land in that province was relatively suitable for rain-fed cultivation of wheat and barley. Conditions for growing chickpea were detected as marginally suitable and unsuitable lands for safflower growing were in the maximum. In most regions, wheat and barley POTENTIAL PRODUCTION showed a moderate to high capability. Potential for chickpea production was higher in the southern regions of the province and safflower enjoyed this situation in the Eastern. SPA for each crop and the GPA for all of them and for various scenarios were calculated then, based on results achieved, the cropping patterns were calculated. The GPA index suggested that cropping patterns that included barley-chickpeas-safflower had the highest value. After that, were wheat-chickpeas and barley-chickpeas compositions.
