CRESPO-AMAYA, Roger M.; PANEQUE-RONDON, Pedro  and  MIRANDA-CABALLERO, Alexander. Determination of the Energy and Operation Costs of the Mechanized Rice Harvest. Rev Cie Téc Agr [online]. 2018, vol.27, n.2, pp. 1-10. ISSN 2071-0054.

The objective of the present study was to determine the energy and operation costs of the mechanized rice harvest and to compare the energy and operating costs of the most used harvesters (Claas Dominator-130 and Claas Crop Tiger C-210) under the conditions of the Agro industrial Grain Company (EAIG) "Los Palacios". During the execution of the work, the methodology established for the calculation of the energy cost of the mechanized operation was applied, as well as the operating indicators were determined. The obtained results allowed knowing the structure of the total energy hourly and of operation for the harvesters studied. When comparing the energy costs per area worked, in the Claas Dominator 130 harvester, these values are 298.92 MJ/ha, while in the Claas Crop Tiger C-210 harvester, they are higher, reaching values of 306.79 MJ/ha, which is equivalent to 6.25 L/ha and 6.71 L/ha of diesel fuel respectively. This is because the Claas Dominator-130 is a machine with higher hourly productivity (4.30 vs. 3.24 ha/h) and a wider working width than the Claas Crop Tiger C-210. With the application of these results the "Los Palacios" (EAIG) is achieved with considerable fuel savings per campaign and greenhouse gas emissions are reduced
