VAZQUEZ MILANES, Hugo Berto; PARRA SERRANO, Luis Raúl; SANCHEZ-GIRON RENEDO, Víctor M e ORTIZ RODRIGUEZ, Alfonso. Analysis of the Productivity and Consumption of Fuel in Farm Groups in a fluvisoil for the Cultivation of Yucca (Manihot esculenta, Crantz) . Rev Cie Téc Agr [online]. 2012, vol.21, n.2, pp. 38-41. ISSN 2071-0054.
The present work was carried out in the basic unit of rural production, "El Palmar", belonging to the Company of Mixed Cultivations “Paquito Rosales Benítez” in the municipality of Yara (Granma. Cuba) during the months of April (2007) to January (2008). The method used was the investigative-analytic one with the photometric technique. There were evaluated the farm groups (tractor-agricultural implements) that employed in four farm technologies (T1, T2, T3 and T4) for the cultivation of the yucca, Rosy Dwarf variety. They were done five observations of the Labor Day for each one of the farm groups aimed to evaluate the fuel consumption and their productivity. The best results in the evaluated indicators corresponded to the technology of minimum ploughing, T2, with a Modified Subsoiler Bayamo and with a disk harrow. In T2 the productivity per hour of net time was 1,34 ha h-1 and the operational-time productivity was 1,27 ha h-1. T2 technology showed other significant differences regarding the rest of the evaluated technologies: it registered the smallest consumption of fuel (32,4 L h-1); that is, 72; 52 and 71 % less than T1, T3 and T4 farm technologies.
