The two-factor randomized block ANOVA model is a parametric test that assumes normality and homogeneity of variance, which may not always be the case. The nonparametric equivalent to this model is the Friedman test, which can handle non-normal and non-homogeneous data without making any assumptions about the underlying distribution. The Kruskal-Wallis and Mann-Whitney tests are nonparametric alternatives to the one-way ANOVA and two-sample t-test, respectively, and are not directly related to the two-factor randomized block design. The chi-square test of equivalence is also not directly related to this design and is used to compare proportions between groups.
