Increasing yield and grain protein concentration (GPC) in wheat (Triticum aestivum L.) without excessive nitrogen (N) rates requires increasing N use efficiency (NUE, yield per available N). We assessed the effects of N rate and timing on yield, GPC, and N nutritional indices of two winter wheat genotypes with similar yield but contrasting GPC. Factorial field experiments evaluated the wheat genotypes ?LCS Chrome? (high GPC) and ?WB?Grainfield? (low GPC), three N rates, and four N timings (?Fall?, 100% of N rate applied at Zadoks GS20; ?Spring?, 100% at GS25; ?Split?, 40% Fall plus 60% Spring; and ?Anthesis?, 40% fall, 50% spring, and 10% at GS61) in six Kansas environments. Yield ranged from 2,853 to 8,023 kg ha-1 and GPC from 88 to 152 g kg-1. Fall and spring N timing had the lowest and greatest yield difference from the zero-N control and showed linear, linear-plateau or no responses to N rate. ?LCS Chrome? had 5 to 19 g kg-1 greater GPC than ?WB?Grainfield?, which was associated with greater post-anthesis N uptake (24 vs 15% of maturity-N uptake), a greater spike N gain between anthesis and maturity (7.4 vs 6.5 g m-2), and greater N recovery efficiency (0.34 vs 0.28 kg kg-1). Greater N rates and Anthesis or Spring N timings increased GPC. The NUE (range: 20?311 kg kg-1) was inversely related to N availability, and Fall N timing had the lowest NUE. Our results highlighted physiological reasons for genotype-specific GPC performance and suggested agronomic opportunities to simultaneously improve wheat yield and GPC.
