1eCAN = encapsulated calcium-ammonium nitrate (5Ca(NO3)2–NH4NO3) – 65.1% nitrate DM basis.
2NCTRL, treatment 2.7 g/kg BW molasses; U, NCTRL + 182 mg/kg BW urea; NIT, NCTRL + 538 mg/kg BW eCAN; UB, treatment U + 58.4 mg/kg BW BSS; NITB, treatment NIT + 58.4 mg/kg BW BSS. Groups contained 5 (NCTRL, U, NIT, UB) and 4 (NITB) experimental units. Largest SEM is provided.
3Observed significance levels for: NPN, effect of NPN, NCTRL vs. the mean of U + NIT + UB + NITB; NS, effect of NPN source (excludes NCTRL); B, effect of BSS (excludes NCTRL); B×N, interaction of BSS and NPN source (excludes NCTRL).
