An in-depth discussion on the research progress and trends in soil nitrogen leaching is essential for development of agricultural sustainability. However, not enough attention has been paid to future research. Using software such as VOSviewer CiteSpace, bibliometric analyses a total 2767 documents Web Science Core Collection were conducted; considered published over last 20 years (2003–2023). The results are follows: (1) output increasing steadily, showing single-discipline dominance agronomy, but trend multidisciplinary cross-research gradually begun emerge recent years. (2) There close cooperation between authors, countries, institutions; main includes modelling management, related management practices types high international profile. (3) components at heart cycling soils, properties, water environments crops, greenhouse gas formation emissions, agronomic hotspot changed applied (4) Increasing considerations measures, deepening microorganisms, constructing complete evaluation system constitute directions. This study can provide valuable references sustainable agriculture.

Vegetable production in the low and mid hills is highly vulnerable to climatic vulnerability. The study evaluated Agricultural Climatic Vulnerability Index (ACVI) for 51 blocks regions using IPCC AR4 conceptual framework. developmental were categorized into three groups (Low, Moderate Highly Vulnerable) collect primary data. A multistage stratified random sampling technique was employed, a pre-tested questionnaire. ACVI findings reveal that Balh Valley most climate-vulnerable block, while Paonta Sahib least. primarily driven by temperature variations Kharif Rabi seasons of exposure dimension. farm income analysis shows decline crop feasibility from high-vulnerability groups. Maximum significantly reduced net returns, except case cauliflower. Rainfall negatively impacted profitability crops such as tomatoes, capsicum peas. However, an increase minimum boosted vegetable balanced use fertilizer pesticide application, diversification increased irrigation coverage mitigated climate change impacts across all vulnerability improved profitability. Among studied, tomato exhibited highest carbon sequestration potential, followed capsicum, pea, French beans significant variation observed level Farmers these have adopted various adaptation strategies, including (76.11%), nutrient management (71.11 %), varietal changes (65.56 water conservation %). To enhance resilience, emphasizes importance technical knowledge, capacity building, adoption better agronomic practices, financial support, comprehensive stakeholder consultation within agricultural allied sectors.

Interaction between burial depth and N source in drip-fertigated maize: Agronomic performance and correlation with spectral indices

Agricultural Water Management, Год журнала: 2024, Номер 301, С. 108951 - 108951

Increasing drought severity and evaporative demand in Mediterranean areas makes it necessary to implement irrigation systems with high water nutrient supply efficiency. The combined management of drip burial depth different nitrogen (N) sources, thus far unexplored, predicting these effects using proximal spectral vegetation indices. A 2-year field experiment was conducted comparing maize yield N uptake from four fertilization treatments: ammonium sulfate (AS), AS the nitrification inhibitor DMPP (AS+INH), calcium nitrate (CN) a control without surface or subsurface (30 cm depth) fertigation. Multispectral data were collected calculate various indices, while chlorophyll content measured soil plant analysis development (SPAD) sensor second year. Subsurface AS+INH increased grain yields compared AS-only (by 12 % 18 %, respectively, P < 0.05). However, this observed only season, as increases content. results show that use CN performed better drip, NH4+-N-based fertilizers recommended for irrigation. Regarding data, at flowering-milky kernel dent phenological stages Normalized Difference Red Edge (NDRE) canopy index (CCCI) two indices best estimated agronomical parameters able discriminate differences between systems. This study highlights potential (i) multispectral sensors drip-fertigated (ii) optimizing crop performance by combining source (DMPP irrigation), relevant implications climate change adaptation (i.e., improvements phenology saving).

Suitable Water–Fertilizer Management and Ozone Synergy Can Enhance Substrate-Based Lettuce Yield and Water–Fertilizer Use Efficiency

Agronomy, Год журнала: 2024, Номер 14(8), С. 1619 - 1619

As living standards rise, enhancing quality has become a central objective for many researchers. Soilless cultivation, known its efficient use of resources, is increasingly used in vegetable production. It critical to develop effective water and fertilizer management strategies achieve high-quality yields promote sustainable development modern agriculture. This study employed an orthogonal experimental design assess the impact varying nutrient solution concentrations (50%, 75%, 100%, 125% Hoagland’s), lower irrigation thresholds (40%, 55%, 70%, 85% field capacity (FC)), ozone (0, 1, 2, 4 mg·L−1) on lettuce growth, yield, quality, water–fertilizer efficiency. The results indicated that fixed enhanced growth metrics lettuce. Similarly, increasing initially improved, then reduced when threshold was constant. Furthermore, maintaining stable while raising concentration boosted, diminished, indicators. Optimal conditions were identified at 75% 100% 0 1 mg·L−1. Variance analysis highlighted significant effects concentration, thresholds, Range revealed optimal combination be FC threshold, mg·L−1, yielding 16.82 t·ha−1 efficiency 40.14 kg·m−3. These findings provide theoretical support advancement soilless cultivation contemporary
