Abstract The purpose of this study was to determine the source of nitrogen used by Panicum maximum Jacq. plants in salt soil. Experimenting pots in a greenhouse with a medium of saline soil. The 2 × 3 factorial design is used in repeated trials. The first factor is calcium sulfate (0 and 2 t ha−1), the second factor is N fertilizer includes (a) without nitrogen = N0, (b) 60 kg N of potassium nitrate (KNO3) and (c) 60 kg N of ammonium sulfate (NH4SO4). The parameters observed were nitrogen uptake, constant growth rate (CGR), biomass yield, crude protein content, NDF, and ADF. The interaction of calcium sulfate and nitrate fertilizer increases CGR, biomass yield, N, CP and NDF uptake. Interaction calcium sulfate and ammonium fertilizer increase CGR, biomass yield, N uptake, CP, and ADF.
