Pearl millet (Pennisetum glaucum R. Br.) water-limited yield gap in Senegal is estimated at 2.2 Mg ha^-1. Proper variety and management selection are critical to the sustainable intensification of millet systems. The objectives of this study were to assess the effect of two pearl millet varieties and different crop management (plant density-nutrient rates) treatments on i) biomass yield, ii) grain yield, and iii) farm profit magnitude and responsiveness. The study was conducted on three sites during the 2017, 2018, and 2019 growing seasons with a total of nine site-years. Two varieties, Souna 3 (traditional) and Thialack 2 (dual-purpose), and 48 management treatments including two plant densities (37–74 × 1000 plants ha^-1) and 24 different levels of nutrient combinations ranging from 0 to 149 kg ha^-1 nitrogen (N, as urea), 0–67 kg ha^-1 phosphorus (P₂O₅, as double super phosphate), 0–33 kg ha^-1 potassium (K₂O, as potassium chloride) and 0–14 987 kg ha^-1 cow manure (M), were tested in all site-years. Thialack 2 presented greater biomass yield in three and grain yield in four site-years (out of nine site-years) relative to Souna 3. Management treatments with greatest magnitude and responsiveness produced on average 4.6 Mg ha^-1 biomass yield with averaged nutrient rates of 102–37–26 NPK, 2 Mg ha^-1 grain yield with averaged nutrient rates of 91–32–24 NPK, 682 USD ha^-1 profit at low biomass and grain prices with averaged nutrient rates of 72–22–21 NPK, and 1183 USD ha^-1 profit at high biomass and grain prices with averaged nutrient rates of 83–29–22 NPK, all at 74 thousand plants ha^-1, regardless of variety used. Five to seven management practices were able to concurrently optimized biomass yield, grain yield, and farmer profit. Sustainably intensifying pearl millet systems by using improved variety and management practices have great potential to promote greater yields and farm profitability in Senegal.

塞内加尔的珍珠粟 ( Pennisetum glaucum R. Br.) 受水限制的产量缺口估计为 2.2 Mg ha ^-1。适当的品种和管理选择对于小米系统的可持续集约化至关重要。本研究的目的是评估两种珍珠粟品种和不同作物管理（植物密度-养分率）处理对 i) 生物量产量、ii) 谷物产量和 iii) 农场利润幅度和响应性的影响。该研究在 2017 年、2018 年和 2019 年生长季节的三个地点进行，共 9 个地点年。两个品种，Souna 3（传统）和 Thialack 2（两用），以及 48 种管理处理，包括两种植物密度（37-74 × 1000 植物 ha ^-1) 和 24 种不同水平的养分组合，范围从 0 到 149 kg ha ^-1氮（N，作为尿素）、0-67 kg ha ^-1磷（P ₂ O ₅，作为双过磷酸钙）、0-33 kg ha ^-1钾（K ₂ O，作为氯化钾）和 0-14 987 kg ha ^-1牛粪（M）在所有地点年进行了测试。与 Souna 3 相比，Thialack 2 在 3 年和 4 年（在 9 年中）表现出更高的生物量产量和谷物产量。具有最大幅度和响应性的管理处理平均产生 4.6 Mg ha ^-1生物量产量和平均养分率102–37–26 NPK, 2 Mg ha ^-1平均养分含量为 91-32-24 NPK 的粮食产量，低生物量和谷物价格下的 682 美元 ha ^-1利润，平均养分含量为 72-22-21 NPK 和高生物量和谷物的1183 美元 ha ^-1利润平均养分率为 83–29–22 NPK 的价格，全部为 74,000 株 ha ^-1，无论使用何种品种。五到七种管理实践能够同时优化生物质产量、粮食产量和农民利润。通过使用改进的品种和管理实践来可持续地强化珍珠粟系统，在提高塞内加尔的产量和农场盈利能力方面具有巨大潜力。
