Abstract

Abstract:

【Objective】 Investigating the impacts of different N application regimes on crop (spring maize) yield and nitrous oxide (N₂O) emission provided the basis for reasonable N (Nitrogen) application and GHG (Greenhouse Gas) emission mitigation in dryland farming of the Loess Plateau. 【Method】 In this study, the impacts of five N application regimes on spring maize (Xianyu 335) yield and N₂O emission were investigated in a short-term (2 years) experiment in Changwu Agro-Ecological Experimental Station, and the treatments included: no fertilizer; conventional N fertilization (Con, 250 kg N•hm^-2); optimized N fertilization (Opt, 200 kg N•hm^-2); optimized N fertilization with slow-release fertilizer (Opt+SR, 200 kg N•hm^-2); optimized N fertilization with dicyandiamide (Opt+DCD, 200 kg N•hm^-2). The N₂O emission fluxes were monitored using sealed static chambers, and the gas chromatograph and the global warming potential (GWP) was calculated. 【Result】 (1) N₂O emissions increased rapidly after N application, reaching a peak on the second day, and rapidly decreased after 10 days of maintenance. Optimized N fertilization significantly decreased N₂O emissions (P<0.05). Compared with Con, the reductions in N₂O emissions under Opt, Opt+DCD, and Opt+SR were 21.4%, 27.6%, and 26.0%, respectively. The GWP of N₂O emissions under Con, Opt, Opt+DCD, and Opt+SR were 425.01, 334.01, 307.83, and 314.57 kgCO₂-eq•hm^-2, respectively. Opt+DCD significantly reduced N₂O emission intensity by 27.8% than that under Con (P<0.05). (2) N₂O emissions were highly correlated with surface soil NH₄⁺-N content (P<0.01), but showed no significant correlation with soil moisture and temperature. (3) Compared with Con, Opt, Opt+DCD, and Opt+SR significantly improved N fertilizer agronomic efficiency (with increases of 25.5%, 25.7%, and 22.2%, respectively) and nitrogen fertilizer partial factor productivity (with increases of 29.9%, 28.7%, and 25.4%, respectively) (P<0.05), whereas they had no significant impact on spring maize yield. 【Conclusion】 In dryland farming of the Loess Plateau, reducing N fertilizer application, applying slow-release fertilizer, and adding nitrification inhibitors properly could promote N₂O emission reduction and increase spring maize yield. Notably, reducing N fertilizer application by 20% and adding nitrification inhibitors not only ensured spring maize yield but also had the best effect on N₂O emission reduction.
