The means are not significantly different within a given season when followed by the same lowercase letter using LSD at p < 0.05. “*” and “**”, indicate significant. PANT, pre-anthesis accumulated nitrogen translocation amount from vegetative organs to grains after anthesis; NAAA, nitrogen accumulation amount after anthesis.
