| Seed is one of the main products in the agricultural sector. Studying production indexes in farms allows for better management of agriculture activities. Sunflower and pumpkin are the most important oilseeds and nut products in the world whose cultivation has expanded greatly in recent years. The production of both products, for the use in oil industrial applications and as nuts, requires the use of various inputs. In the present research, the material and energy indexes in sunflower and pumpkin seed, as the main oilseed crops, production systems were analyzed and compared. The input-output information of the studied production systems in the present research was collected through face-to-face interviews with 50 sunflower and 30 pumpkin seed farmers using the random sampling method. The input and output materials and energy of the farms were calculated and compared. The values of the input to total output index were calculated for all inputs of the systems. On the basis of the energy equivalents of inputs and outputs, the values of the indicators including energy ratio, energy productivity, energy intensity, and net energy gain were calculated. Energy forms were calculated and compared in terms of energy equivalent and resource for the systems. The mean of total energy input of sunflower production farms was equal to 19.95 GJ.ha-1 which was higher than that of pumpkin production farms with the amount of 10.53 GJ.ha-1. The energy efficiency of pumpkin production farms (2.20) was higher than that of sunflower production farms (1.62). The main energy consumer input in sunflower farms was diesel fuel with a share of 34.95% but the corresponding input in pumpkin production farms was fertilizer with a share of 73.54%. | ||
