To investigate the coupling effects of biochar and nitrogen fertilizer on tomato growth, uptake utilization (NUU), soil environment, a pot experiment was conducted using 15N-tracing technology from March to July 2021 September January 2022. Three application rates (B0, B1, B2; 0, 3, 6 t/hm2, respectively) three levels (N1, N2, N3; 150, 300, 450 kg/hm2, were set up. The results show that yield, rate 15N uptake, derived (Ndfs), total (TN), utilization, recovery tomatoes improved under application, but (Ndff) gradually decreased. A Pearson correlation analysis showed Ndfs, TN, rhizosphere organic matter, carbon, TN significantly positively correlated with yield lycopene content tomatoes. comprehensive benefit evaluated based combination weighting help technique for order preference by similarity ideal solution (TOPSIS). This indicates best planting mode B2N2 treatment, t/hm2 300 alternative partial root-zone irrigation.

Abstract Maintaining or even increasing crop yields while reducing nitrous oxide (N 2 O) emissions is necessary to reconcile food security and climate change, the metric of yield‐scaled N O emission (i.e., per unit yield) at present poorly understood. Here we conducted a global meta‐analysis with more than 6000 observations explore variation patterns controlling factors for maize, wheat rice associated potential mitigation options. Our results showed that average across all available data followed order (322 g Mg −1 , 95% confidence interval [CI]: 301–346) > maize (211 CI: 198–225) (153 144–163). Yield‐scaled individual crops were generally higher in tropical subtropical zones temperate zones, also trend towards lower intensities from low high latitudes. This was better explained by climatic edaphic fertilizer management, their combined effect predicted 70% variance. Furthermore, our analysis significant decrease use efficiency production systems cereal >10 ha (maize), 6.6 (wheat) 6.8 (rice), respectively. highlights indicators can be used as valuable proxies reconciling trade‐offs between mitigation. For three major staple crops, fertilization up 30%, optimizing timing placement application using enhanced‐efficiency fertilizers significantly reduced similar yields. data‐driven assessment provides some key guidance developing effective targeted adaptation strategies sustainable intensification production.

Here, we investigated effects ratios (1/9, 3/7, 7/3, 9/1) on leaf stoichiometry (LF), chlorophyll content, fluorescence T. grandis. We used ammonium nitrate as IN source an equal proportion urea glycine ON source. The altered photochemical efficiency Although P content increased significantly after treatment, N N:P maintained a certain homeostasis. plants performed best at ratio highest values chlorophyll-a, total chlorophyll, maximum efficiency, photosynthetic performance index. Thus, both types should be considered when assessing responses to increasing future. Our results also indicated that concentration was positively correlated Chl, Fv/Fm, PIabs. This result further indicates importance element for against background deposition. Overall, these indicate might cope changes environment by maintaining homeostasis plasticity PSII activity.
