Lower efficiency of agricultural inputs in the four conventional rice planting methods limits productivity and environmental benefits Southwest China. Thus, we developed a machine-learning-based decision-making system for achieving optimal comprehensive during production. Based on benefits, implemented strategies these methods: reducing N fertilizer by 16% while increasing seed 9% mechanical transplanting (MT) method improved yield benefits; 10-12% direct seeding (MD) decreased impacts; N-K fertilizers 15-33% manual (MAT) its 7-14%; applying N-P-K ratio 2:1:2 (MAD) enhanced yield. Our study provides improving methods, with MT being more beneficial optimizing especially impacts,

Agriculture significantly impacts the global environment, contributing to greenhouse gas (GHG) emissions, air and water pollution, biodiversity loss. As population grows demands higher agricultural output, these environmental are expected intensify. Among contributors, China, with its vast prominent sector, plays a leading role in GHG emissions. Understanding mitigating China is crucial for addressing broader challenges. To address key issues, we conducted study on dynamic impact of variables (agricultural land, fertilizer consumption, energy use agriculture, value-added, forest livestock, fisheries, crop production) emissions by utilizing data from 1990 2020, employed linear non-linear autoregressive distributed lag (ARDL NARDL) models. In study, co-integration analysis confirms long-run relationship between variables, long-term findings ARDL model reveal important insights, increased land use, production, livestock fishery production increases can be reduced increasing long term. Furthermore, asymmetric NARDL regression applied three positive shock results confirm that (AGL+), consumption (FC+), (EUA+) contribute However, adverse shocks (AGL−), (FC−), (EUA−) could compress These offer valuable implications Chinese authorities' focus expanding using more renewable energy, minimizing usage chemicals agriculture. measures help mitigate while promoting sustainable practices.

Optimized fertilizer use improves crop yield and mitigates environmental pollution associated with production. Fertilizer plant density are core strategies to ensure food security cope climate change. However, little is known about the long-term interactive effect of reduced nitrogen (N) increased on C (Carbon) balance. In this study, field experiments were conducted in a double-cropping rice region evaluate effects carbon footprint (CF) by crop-based soil-based methods. Treatments set for 10% reduction N coupling conventional (N1D1), 20% higher (N1D2), 40% (N1D3), (N2D1), (N2D2), (N2D3), prevailing practices as control, density, dose. Results showed that continued increase increasing density; under same reducing more beneficial improvement CH4 emission reduction. Compared CK, application generally annual yields 7.34–23.25% average, emissions 16.19–22.11%, resulting 22.24–26.82%, 22.08–32.85%.

The Nitrogen Nutrition Index (NNI), based on the Critical Concentration (Nc), is widely utilized to evaluate crop nitrogen nutrition. However, impact of water deficit Nc remains unclear. To address this, a 3-year joint water-nitrogen regulation experiment winter wheat was conducted investigate responses dilution curve parameters (A1 and A2 in ​= ​A1DM−A2, where DM represents aboveground dry biomass), accumulation (NA), grain yield (GY) different management strategies. study employed Bayesian statistical methods establish curve, which revealed slightly lower compared that derived using classical methods. posterior distribution indicated substantial overlap A1 (89.8%) (89.4%) between irrigation (DI) full (FI). parameter 67.2% rainfed irrigated (DI FI) treatments, whereas for A2, it only 29.9%. Analysis variance showed significant difference (p ​< ​0.05) but no differences were found ​> DI FI treatments. Additionally, NA GY displayed insignificant treatments; however, they were, overage, significantly higher by 31.2% 23.2%, respectively, under conditions conditions. This first demonstrate severe (rainfed conditions) affects underscoring importance considering actual applying NNI fertilizer management.

Rice-rape, rice-wheat and rice-garlic rotations are common cropping systems in Southwest China have played a significant role ensuring ecological economic benefits (EB) addressing the challenges of China's food security region. But regionally, crop yields these rotation 1.25%-14.73% lower than national average. Intelligent decision-making with machine learning can analyze key factors for obtaining better benefits, but it is rarely used to enhance probability such China. Thus, we data-intensive approach construct intelligent provide strategies improving rice-rape, rice-wheat, The results show that raising yield partial fertilizer productivity (PFP) by increasing seed input under high obtained optimal 10% system. Obtaining greenhouse gas (GHG) emissions N application decreasing K suboptimal an 8% rice-rape Reducing P PFP lowest (8%) Based on predictive analysis random forest model decreases 25% increases 74%, respectively, system, 54% 36%, 38% 4% 65% 23% could be further optimized 17-34% different all measures improve effectiveness varying degrees.

The photosynthetic-nitrogen use efficiency (PNUE) of Brassica napus L. is reported to increase under low nitrogen (N) condition. However, the underlying physiological mechanisms are unclear. In this study, in low-nitrogen condition were investigated by assessing changes plant architecture, light reception, allocation, and leaf tissue structure. plants exhibited dwarf, upright, compact phenotype Although total photons received decreased, average photosynthetic photon flux density remained unchanged. reception (NPRE, calculated as photons/N accumulation leaves) was significantly increased 76.61%–100.63%. proportion allocated for photosynthesis 22.06%–38.86%. Moreover, although thickness unchanged, epidermal increased, spongy tissues became thinner. mesophyll cells chloroplasts increased. Low-nitrogen decreased resistance CO2 transport stomatal conductance (gs), intercellular carbon dioxide concentration (Ci), (gm), (Cc). Correlation analysis revealed that allocation leaves, structure correlated with PNUE. Random forest storage primary factors positively negatively impacting efficiency, respectively. This study enhanced understanding mechanism PNUE B.

Agricultural strategies are urgently needed to mitigate greenhouse gas emissions without reducing crop yield. Seedling rate per hill will affect the quantity and quality of tillers, which may rice yield CH4 emissions. Therefore, it is hypothesized that high yields with low yield-scaled could be achieved optimal seedling hill. A field experiment was conducted three densities (low rate, LSR; moderate MSR; HSR) for two consecutive seasons. The fluxes were determined by static chamber–GC method. results showed no significant differences in yields, seasonal emissions, or between treatments. For early rice, HSR tended achieve increasing As late MSR similar yield, have lower comparison HSR. suggest choosing an appropriate increase grain while maintaining comparable can a promising option reduce from paddies.
