Seleção e avaliação econômica de nova tecnologia sob condições de risco: o caso do sorgo forrageiro

Abstract

The objectives of this study were to select, with and without fertilization, the tecnology offering least risk and highest profitability, and to indicate the economically most viable technology for the Northeast region. Production data were obtained from experiments carried out during the 1979/82 period, by the Departament of Crop Science at the Experimental Farm in the Curu Valley, belonging to the Federal University of Ceará. The method of Hanoch & Levy utilized to select alternative technologies, showed a discriminatory power of 90%. The application of the method proposed by Hanoch & Levy and the results obtained from the economic evaluation, made possible to identify technology "E" as being the most efficient, in the two situations (with and without fertilizers).
