The study aimed to assess the effects of combined application of urea nitrogen (N) and tank* silt (TS) on greenhouse gases (GHG) emissions [i.e., carbon dioxide (CO2) and nitrous oxide (N2O)] and agronomic productivity of maize-horsegram system. A factorial [urea (0, 60, 120, and 180 kg N ha−1)] and tank silt (0 and 30 t ha−1) replicated thrice randomized block design was employed for this investigation. Results of the study showed that maize grain yield was significantly influenced by the sole application of both N fertilizer and TS. When both the N fertilizer and TS were combined, the grain yield was significantly (p N60 > N0. However, N fertilizer application influenced the cCO2 emissions (r = 0.83), and significantly increased the cN2O emission (r = 0.99). Therefore, optimum and timely application of urea combined with TS is recommended as an effective strategy to combat GHG-based emissions (specifically N2O based) in semiarid rainfed regions.
