Description Nitrogen (N) is one of the primary macronutrients required for crop growth and yield.
This nutrient is especially limiting in the dry and low fertility soils where pearl millet
[Pennisetum glaucum (L.) R. Br] is typically grown. Globally, pearl millet is the sixth most
important cereal grown by subsistence farmers in the arid and semi-arid regions of
sub-Saharan Africa and the Indian subcontinent. Most of these agro-ecologies have
low N in the root zone soil strata. Therefore, there is an immense need to identify lines
that use nitrogen efficiently. A set of 380 diverse pearl millet lines consisting of a global
diversity panel (345), parents of mapping populations (20), and standard checks (15)
were evaluated in an alpha-lattice design with two replications, 25 blocks, a three-row
plot for 11 nitrogen use efficiency (NUE) related traits across three growing seasons
(Summer 2017, Rainy 2017, and Summer 2018) in an N-depleted precision field under
three different N levels (0%-N0, 50%-N50, 100%-N100 of recommended N, i.e., 100 kg
