N2 - An experiment was conducted to examine the performance of pearl millet under different nitrogen (N) fertilizer rates in two locations in the semiarid zone of Nigeria. *e objective was to evaluate the effects of different N rates on pearl millet yields, water and nitrogen-use efficiency, and profitability. Grain yield increased by 23, 26, 32, 32, and 27% and by 38, 41, 54, 58, and 56% compared to unfertilized plots when applying 20, 40, 60, 80, and 100 kg Nha?1 in Minjibir and Gambawa, respectively. Similarly, stalk yield increased by 4, 3, 9, 9, and 9% and by 16, 24, 36, 40, and 37% compared to unfertilized plot when applying 20, 40, 60, 80, and 100 kg Nha?1 in Minjibir and Gambawa, respectively. *e variations in GY that could be explained by TWU and NUE were 28% and 26% in Minjibir and 46% and 41%, respectively, in Gambawa. *ere was a strong and positive correlation (R = 0.81 and R = 0.95) between WUE and GY across N-fertilizer rates and pearl millet varieties in both locations. An increase in N-fertilizer levels increased WUE, confirming the optimal application of 60 kg Nha?1 in Minjibir and of 80 kg Nha?1 in Gambawa. Similarly, the highest net economic return (NER) of US$610 ha?1 was obtained at 60 kg Nha?1 in Minjibir and the highest NER of US$223 ha?1 was obtained at an application rate of 80 kg Nha?1 in Gambawa. Break-even yield was above 1000 kg ha?1, signifying that average farmer with a mean yield of less than 1000 kg ha?1 produces millet at a loss.
