Abstract
The present study was conducted with the aim of investigating the productivity and energy indicators of paddy, wheat, fodder corn, seed corn and citrus fruits in the Tajan plain in the crop year 1401-02. Then sampling was done based on 300 designed questionnaires. The collected information includes man-days, working hours of machinery, fuel consumption of machinery, consumption of nitrogen, phosphate, potassium fertilizers, consumption of various types of chemical pesticides, including herbicides and fungi. Pesticides and insecticides were in liters per hectare, the amount of water consumed was in cubic meters per hectare, the amount of seeds consumed was in kilograms per hectare and the amount of production. The results showed that the highest amount of energy in Tajan plain in the input energy sector for paddy crop (593256 mega joules per hectare), output energy for fodder corn product (141795 mega joules per hectare), net energy for fodder corn product (110758.53 mega joules per hectare) and energy efficiency was also for fodder corn product (1.1 kg/mega joules). Also, according to the obtained results, it was found that in all the products, the four inputs of water consumption, nitrogen fertilizer, machinery and fuel have the highest amount. The results of the investigation of the physical productivity of water showed that the highest productivity in the Tajan plain is related to fodder corn and the lowest productivity is related to rice 0.5 kg/m3. In general, to increase the productivity of lands and products in terms of productivity and energy indicators, it is necessary to use the cultivation of plants with appropriate performance, the highest level of productivity and the lowest level of input consumption. research, fodder corn had more suitable conditions.
