HERNANDEZ PEREZ, Melisa María  e  DIAZ CASTELLANOS, Manuel. Energy efficiency of the common bean (Phaseolus vulgaris L.) cv. Buenaventura. Ctro. Agr. [online]. 2019, vol.46, n.3, pp. 96-98. ISSN 0253-5785.

The work was carried out in the "San Ramón" farm of Santa Clara municipality, Villa Clara province, with the objective of determining the energy efficiency of the common bean cultivar Buenaventura. For this purpose, the energy equivalents of the inputs and outputs of the system were used. The sources of direct energy (fossil fuels) and indirect energy (fertilizers, pesticides and seeds) were taken into account. The results showed that this cultivar was very efficient energetically with a value of 1.57. The largest amount of energy consumed in the system was determined by chemical synthesis inputs (fertilizers and pesticides).
