In both arid and semi-arid regions, adopting field mulching can effectively optimize soil moisture distribution, enhance crop yields, improve water productivity. While acknowledging its advantages, seems insufficient for maintaining high productivity due to the increasing frequency of extreme weather. Furthermore, drought often coincides with critical growth stages, necessitating implementation agricultural irrigation ensure normal growth. Accordingly, we conducted a three-year experiment from 2021 2023 including three typical methods (no mulching, NM; straw SM; plastic film FM) supplementary strategies (irrigated at branching stage (V4), W1; irrigated pod-filling (R2), W2; V4 R2 stage, W3). Throughout entire period, monitored conditions each treatment, measured leaf physiological parameters crucial assessed soybean yields (WP). Our findings indicated that, relative SM NM, FM maintains optimal balance, augments chlorophyll content, enhances photosynthesis, resulting in an average yield increase 17.0% 38.3% over growing seasons. Additionally, also significantly affects seed soybean. FMW2 achieved higher (4307.5 kg ha−1, 3-year averaged), had insignificant difference highest 4568.6 than other treatments. Similarly, area index, net photosynthetic rate (Pn) transpiration (Tr) presented between FMW3, while WUEleaf (Pn/Tr) obviously that FMW3. As result, WP 12.2 ha−1 mm−1 seasons, compared treatments, ranges 5.6% 46.7%. summary, treatment optimized distribution meet demands soybeans during reproductive achieving beneficial balance production by regulating functional parameters. Future research will explore more specific scheduling techniques (e.g., precision irrigation, deficit sensor-based management systems) integrating innovative materials biodegradable films) further resilience under evolving climatic conditions.

Endophytic mycobiomes are an integral part of crops in agricultural systems. Fertilization is a conventional practice to improve and may alter the soil plant In agroecosystems, Nature Based Solutions (NBS) key strategies for suitability. Investigating under N flux can provide fundamental data constructive NBS strategies. this study, effects nitrogen (N) fertilizer treatments on fungal compositions soil-maize systems were systematically investigated field experiments at six rates (F0, F72, F126, F180, F234, F280 kg N/ha) northern China. Meta-omics amplicon sequencing internal transcribed spacer (ITS) region was employed study community dynamics, network correlation, metabolic functional assemblies, abundance patterns core fungi. This found that communities significantly higher 72 N/ha compared with control other treatments. Network topology increased maize fungi (R2 = 0.69) but decreased 0.51). Abundances carbon–nitrogen metabolizing genes (Ure, AMT, gdhA GDH) correlated assembled by stochastic processes. Additionally, relative Ascomycota (67.26 %) dominant soil, whereas Basidiomycota (61. 73 prevailed samples N/ha. Moreover, Sporidiobolus, Alternaria, Fusarium, Penicillium served as conserved genera positively NH4+-N mg/kg, NO2–-N mg/kg NO3–-N pH components. Furthermore, selective tested confirmed increase growth rate utilization maize.
