    Estudio comparativo y manejo de dos sistemas de producción: convencional y limpio en el cultivo de papa (Solanum tuberosum)
    (2017) Escobar Brito, Humberto Bernardo; Valle Velástegui., Edgar Luciano
    The present investigation was carried out between October 2015 and January 2016, in the property of Mr. Humberto Escobar, producer of potato for commercialization, located in the canton of Ambato, parish of Augusto N. Martínez, with the purpose of evaluating two production systems: Conventional and clean, in potato cultivation (Solanum tuberosum), using the unique variety. The design of unpaired plots was applied, applying the "t" test to evaluate the variables under study. The main objective of the trial was to determine and document technical, ecological and sociocultural advantages and disadvantages of the systems under study, agronomic response and economic analysis. In the conventional system as well as the clean system a similar response of the culture was obtained in all variables analyzed statistically. As far as the surveys carried out on the students claim that they receive formal instruction on agricultural production systems, producers use mainly synthetic inputs. In both production systems the tubers maintained residual levels below the permitted limits. From the economic point of view both systems are profitable for the local market. Descriptors: conventional and clean production systems, unpaired plots, t-tests, ecological, sociocultural, agronomic response, economic analysis, macronutrient levels, surveys, residuality.
