Optimizing sowing patterns in winter wheat can reduce N₂O emissions and improve grain yield and NUE by enhancing N uptake.

ABSTRACT: Increasing nitrogen (N) input is essential to satisfy the rising global wheat demand, but this increases nitrous oxide (N₂O) emissions, thereby exacerbating global climate change. Higher yields accompanied by reduced N₂O emissions are essential to synergistically reduce greenhouse warming and ensure global food security. In this study, we conducted a trial using two sowing patterns (conventional drilling sowing [CD] and wide belt sowing [WB], with seedling belt widths of 2-3 and 8-10 cm, respectively) with four N rates (0, 168, 240, and 312 kg ha^-1, hereafter N0, N168, N240, and N312, respectively) during the 2019-2020 and 2020-2021 growing seasons. We investigated the impacts of growing season, sowing pattern, and N rate on N₂O emissions, N
