Soil microorganisms play vital roles in energy flow and soil nutrient cycling and, thus, are important for crop production. A detailed understanding of the complex responses microbial communities to diverse organic manure chemical fertilizers (CFs) is crucial agroecosystem sustainability. However, little known about response fungal nutrients CFs, especially under double-rice cropping systems. In this study, we investigated effects application combined CFs various fertilization strategies, such as no N fertilizer (Neg-CF); 100% (Pos-CF); 60% cattle (CM) + 40% CF (high-CM); 30% CM 70% (low-CM); poultry (PM) (high-PM), PM (low-PM) on communities' structure diversity, environmental variables, rice yield. Results showed that synthetic plus addition significantly increased fertility grain yield compared sole CFs' application. Moreover, changed community relative abundance fungi phyla Ascomycota, Basidiomycota, Mortierellomycota, Rozellomycota. The abundances dramatically differed at each taxonomic level, between manured non-manured regimes. Principal coordinates analysis (PCoA) exhibited greater impacts amendments than distributions. Redundancy dominant were positively correlated with pH, C (SOC), total N, biomass C, was strongly affected by SOC. Network explored positive relationships could increase their adaptability relevant environments. addition, structural equation model (SEM) shows relationship biomass, nutrients, SEM contents availability directly affect yield, while indirectly through production levels. Our results suggest altered biochemical traits counteracted some adverse fertilizer. Overall, findings research integrated a better approach improving health

The continuous application of chemical fertilizers in vegetable cropping has led to deterioration the soil environment and reduced yield quality. objective this study was evaluate effect combining bio-organic on cauliflower yield, biochemical properties, bacterial community. Six treatments were established: no fertilizer (CK, control), (CF, conventional dosage for region), balanced fertilization (BF, 30% reduction fertilizers), plus 3,000, 6,000, or 12,000 kg.ha –1 (Lvneng Ruiqi Biotechnology Co., Ltd., Gansu, China) (BF + OF1, BF OF2, OF3, respectively). A two-season field experiment with conducted under different irrigation districts along Yellow River, Northwest China. results indicate that organic matter, total potassium content, enzyme activity generally higher than those CF treatment. Compared treatment, treatment increased matter relative abundance. Moreover, alpha-diversity fertilization. predominant phyla, including Proteobacteria, Actinobacteria, Gemmatimonadetes, Chloroflexi, main contributors microbiome shift, as demonstrated by their remarkable enrichment OF2 OF3 treatments. Furthermore, Pearson correlation analyses show significant correlations among available P K, electrical conductivity, abundance potentially beneficial microbial groups, such genera Massilia, Bacillus , Lysobacter Nitrosospira . Overall, suggests are essential ensure fertility long-term sustainable green productivity.

The rice seed sub-sector plays a vital role in the self-sufficiency of grain and food security context changing climate. Thus, it is imperative to understand perception growers towards climate change identify major adaptation strategies against along with their significant determinants. In this light, our study used data from 223 Chitwan district Nepal using purposive sampling followed by simple random Bharatpur Metropolitan City Madi Municipality. Descriptive statistics were illustrate strategies. categorized as adopters or non-adopters adoption index. Probit regression was determine determinants findings revealed that 71% perceived change: increased temperature decreased frequency rainfall. Varietal selection, green manuring, planting time, improved water management nutrient adopted area. From analysis, years formal education, experience, contact extension agents training found be farmers more likely adopt It therefore recommended local provincial-level governments explore institutional service provision system socio-economic characteristics while considering location for better farm-level useful policymakers deliberately target services face change. identified are applicable farming similar agro-ecological regions globally.

Conventional farming systems are highly reliant on chemical fertilizers (CFs), which adversely affect soil quality, crop production and the environment. One of major current challenges agriculture is finding ways to increase health yield sustainably. Manure application as a substitute for CF an alternative fertilization strategy maintaining biodiversity. However, little known about complex response bacterial communities nutrients manure CFs application. This study reports nutrients, rice yield, microbial community structure 2 years continuous The consisted six treatments: no N fertilizer control (Neg-Con); 100% (Pos-Con); 60% cattle (CM) + 40% (High-CM); 30% CM 70% (Low-CM); poultry (PM) (High-PM), PM (Low-PM). We used high-throughput sequencing 16S ribosomal RNA gene amplicons characterize communities. Results revealed that addition significantly altered composition structure; enhanced relative abundance phyla Proteobacteria, Chloroflexi, Firmicutes, Acidobacteria, Planctomycetes. Organic treatments, particularly high had highest measured diversity all treatments. Similarly, integrated increased biochemical traits [i.e., pH, total (TN), organic C (SOC), biomass (MBN), (MBC)] grain yield. Average increases in SOC, TN, MBN, MBC were 43.66, 31.57, 24.34, 49.45%, respectively, over High-PM compared with Pos-Con. Redundancy analysis showed dominant bacteria correlated biomass, but Proteobacteria was strongly environmental factors such MBC. employed structural equation model examine relationship between among supported hypothesis nutrient content availability directly while indirectly through levels.

Food security issues continue to be a challenge in most parts of the globe, especially sub-Saharan Africa (SSA). Several research attempts on addressing this issue have mainly been nutrient replenishment using combined application organic amendments and mineral fertilizer inputs. However, there is limited information available potential mechanisms underlying interactions associated with co-application fertilizers. Therefore, review focuses crop interactions, particular emphasis improved synchrony, priming effect, general soil fertility improvement balanced proportion nutrients required by crops. Following brief overview mechanisms, describes four common pre-determined ratios plants depending its life cycle, environment genotypic characteristics order attain crop's maximum genetic potential. The concludes need for future understudy causing interaction under cropping systems, so as apply at appropriate time synchronize release uptake, utmost goal promoting sustainable production enhancing food security.

The long-term utilization of inorganic fertilizers in pakchoi cultivation can result increased nitrate levels, potentially posing health risks to human consumers. For this study, we investigated the efficacy organic as a promising alternative for enhancing soil structure, improving fertility, and increasing yield pakchoi. A two-year field trial was conducted from 2022 2023 examine effects combined application fertilizer on growth Three types irrigation water, namely fresh water (F), brackish (B), magnetized–ionized (MIB), were used combination with five different rates (0, 20, 40, 60, 80 kg/ha, denoted 0, 1, 2, 3, 4). results revealed that treatments F2, F3, B2, B3, MIB3 significantly improved indexes Notably, resulted an earlier onset fast period leaf area index weight. During period, observed highest cumulative growing degree days (ΔCGDD) values, which 628.36 °C plant height (MIB4), 475.01 (B3), 259.73 weight 416.82 dry matter accumulation (B3). logistic model indicated increase eigenvalue at rate 60 while excessive fertilization had inhibitory effects. Under irrigation, both demonstrated significant positive yield, having particularly noteworthy direct effect coefficient 0.935. MIB superior advantages promoting growth, leading higher compared traditional irrigation. maximum value each exerted influence its respective parameter, whereas ΔCGDD relatively smaller or negative effect.
