WS: wheat straw, OLPR: olive pruning residues, I: initial substrate, and R: residual. Values are mean ± SD. Means within the same column followed by the same letters of lowercase (corresponding to initial substrate: I) or uppercase (corresponding to residual substrate: R) are not significantly different at according to Duncan’s multiple range test.
