Nitrogen (N) losses are dominant under alkaline soil due to excessive use of N fertilizers, but low nitrogen use efficiency (NUE). The objective of this study was to determine the effects of Acacia prunings biochar (BC) at 0, 10, 20 and 30 t ha-1 rates combined with 0, 90, 120 and 150 kg N applied lonely from urea, farm yard manure (FYN), poultry manure (PM) on Wheat yield components, NUE and its associated parameters during 2 years of field experiment (2015-2017). The results showed that the application of only BC significantly improved thousand-grain weight (TGW), grain spike-1, NUE, and nitrogen uptake efficiency (NUpE) by 10.81, 9.02, 21.35, and 16.43% when compared to the BC control. Similarly, the application of only N management significantly improved TGW, grain spike-1, nitrogen utilization efficiency (NUtE), and nitrogen harvest index (NHI) by 32.14, 27.98, 4.47, and 16.66%, respectively, over absolute control when averaged across the years. Moreover, BC + N fertilizers significantly affected all of the above parameters. Hence, it can be summarized from our study that the combined application of 20 t BC and 150 kg N from poultry manure significantly improved yield components of wheat as well as NUE of fertilizers under semi-arid conditions.
