Determination of energy usege efficiency of sunflower plant produced in Hayrabolu, Tekirdağ

In this study, it is aimed to determine the energy inputs and outputs of the first and second oil sunflower production and to determine the energy efficiency in production in Hayrabolu province of Tekirdağ city. In the study, the first product oil sunflower production enterprises according to the size of the land 0,1-10 ha, 10,1-20 ha, >20 ha and the second product is grouped as oil producing enterprises sunflower production. A total of 351 from the first product sunflower production enterprises and 87 from the second product sunflower production enterprises were collected and the data were collected and evaluated. According to the results of the study, the highest energy input per unit production area (ha) was 12182,4 MJ/ha in the second product oil sunflower group. The lowest energy input amounted to 8302,8 MJ/ha in the >20 ha operating group. The energy inputs in other operating groups are 8358,9 MJ/ha in the enterprise group of 0,1-10 ha, respectively, and 8413,5 MJ/ha in the enterprise group of 10,1-20 ha. When the energy inputs in enterprises are examined, the highest consumption is; irrigation, fuel and fertilizer energy. When the business groups are analyzed, the yield and energy output per unit production area (ha) are respectively; Yields 2654.3 kg/ha and 69808.1 MJ/ha in the >20 ha enterprise group, the yield of 2596.3 kg/ha and 68282.7 MJ/ha in the second product oil sunflower operating group, 2470 kg/ha and 64961 MJ/ha in the group of 10,1-20 ha , in the operational group of 0.1-10 ha 2239.8 kg/ha and 58906.7 MJ/ha were calculated. When all the enterprises are examined, the most efficient business group is >20 ha in the business group; Net energy efficiency was determined as 61505,3 MJ/ha, specific energy value was 3,13 MJ/kg, energy productivity value was 0,32 kg/MJ and energy ratio was 8,41.
