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. date: 2020-08 date_type: published publication: International Journal of Agronomy (TSI) volume: 2020 publisher: Hindawi pagerange: 1-12 id_number: doi:10.1155/2020/1802460 refereed: TRUE issn: 1687-8159 official_url: https://doi.org/10.1155/2020/1802460 related_url_url: https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=10.1155%2F2020%2F1802460&btnG= related_url_type: pub citation: Ajeigbe, H A and Akinseye, F M and Kamara, A Y and Tukur, A Z and Inuwa, A H (2020) Productivity, Water- and Nitrogen-Use Efficiency, and Profitability of Pearl Millet (Pennisetum glaucum) under Different Nitrogen Applications in Semiarid Region of Nigeria.
