Application of balance model in assessing inter-provincial regarding agro-chemical inputs use efficiency

Current research aims to measure inter-provincial efficiency by balance model under agricultural policies to reduce chemical inputs (fertilizers and pesticides) for wheat and barley crops. Therefore data for wheat and barley related inputs such: land, seed, fertilizer (nitrate, phosphate and other fertilizer), pesticides (insecticide, herbicide and fungicide) and yield was collected through office of statistical and information, affiliated to the Ministry of Agricultural Jihad in cropping year 2008-2009. Using basic CCR model (disregarding strategic policies), balance model (considering strategic policies) and balance factor (ratio of score extracted from current two models) the provincial efficiency was calculated. The results showed that despite some deprived provinces (Eilam, Bushehr, Lorestan, Charmohal & Bakhtiari and Khozestan) attain high score in balance factor but they have been in low level of efficacy because of considering agricultural sustainable development macro policies. While some developed province (Tehran, Qom, Esfahan, Mazandaran and Markazi) have favorite situation in efficiency score but weak score in balance score. This implies that these provinces couldn’t reflect on agro-environmental macro policies.
