Sorghum-Sudangrass was used in randomized complete block to test the effects of a bio-inoculant (BI) and nitrogen (N) application on dry matter (DM) yield determination and forage quality parameters (CP, TDN, ADF, NDF Ca, and P) and 72 h in situ digestibility at two harvest periods (H1 and H2). No effects of BI or N (P>0.05) were noted in any of the quality, yield or digestibility variables. An effect of H was noted in all quality, DM yield and digestibility data (P<0.01). Samples obtained at H1 were higher in quality (P<0.01), yielded less DM (P<0.01) and had greater in situ digestibility (P<0.01) A harvest x N interaction (P<0.05) existed for DM yield and digestibility. Moreover, a harvest x BI interaction existed (P<0.05), for digestibility.
