Abstract

Efficient use of energy in agro-ecosystems is supposed to reduce environmental problems, conserve natural resources and enhance agricultural sustainability. The present study was conducted in order to evaluate the energy use efficiency and also economic indicators in conventional safflower production systems in Isfahan Province during 2011-2012. Information used in this study was obtained from face-to-face interviews with safflower growers and the complementary data provided by Ministry of Agriculture of Iran. Economic and energy indices were estimated by using their input and output equivalents. The total energy consumed in safflower farms was 39145 MJ ha-1, of which the contributions of direct, indirect, renewable and non-renewable energies were 66.3, 33.7, 19.1, and 80.9%, respectively. Total energy output and energy use efficiency were calculated to be 66950 MJ ha-1 and 1.71, respectively. The main contributors to the energy used in safflower production were diesel fuel (44.1%), nitrogen fertilizer (22.2%) and irrigation water (14.9%). Gross and net returns were 943.8 and 115.7 $ ha-1, respectively, the benefit-to-cost ratio was 1.09 and productivity was 1.76 kg $ -1. It seems that in terms of energy use efficiency and economic analysis safflower farms do not have a sufficiently positive condition.
