Coeficientes de uniformidade: sensibilidade a mudanças nos fatores operacionais.

Abstract

The aim of this work was to evaluate the sensitivity of uniformity coefficients. Tests were conducted at the Laboratory in Universidade Federal de Viçosa. Sensitivity of coefficients was evaluated taking into account the deviation obtained when chaging a certain factor. The coeffcient with the greatest deviation was considered the most sensivite. Results obtained showed that: 1. coefficient proposed by Benami and Hore was generally the most sensivite to changes in factors, Christiansen’s, Hart’s and Karmeli’s coeficient were generally the least sensitive. 2. Both sprinkling and lateral spacing are the factors that mostly influences in coefficients and the test duration time the least influenced.
