A two-year (2023–24 and 2024–25) split-plot field experiment was conducted within a mid-term conservation agriculture (CA)-based maize-wheat-greengram system to evaluate nine phosphorus fertigation levels and split application schedules through subsurface drip fertigation (SSDF), combined with two residue management practices (retention: R+, no-retention: R-), on growth, yield, water productivity, economics, and resource-use efficiency and post-harvest available phosphorus of wheat (cv. HD 2967). Treatments included no-P (control), SSDF of P as DAP at 50, 75, and 100% of the recommended dose (RDP; 60 kg P 2 O 5 ha −1 ) applied either fully as basal (10 DAS) or split (10 and 25 DAS), along with a nano-DAP foliar spray, compared against conventional CA with flood irrigation and basal broadcast P (CA-FI-100% RDP-B). SSDF treatments consumed only 178–275 mm of total water input against 437–452 mm under flood irrigation. Among SSDF treatments, 100% RDP applied in two splits (100% RDP-2S) consistently recorded the highest growth attributes, grain yield (6.23 and 6.31 t ha −1 ), and economic returns (BCR: 1.8–2) across both years, improving grain yield by 10.6–11.5% and net returns by 13.7% over CA-FI-100% RDP-B. Notably, 75% RDP-2S was statistically comparable to 100% RDP-2S for yield and profitability, demonstrating that a 25% reduction in P dose under precision SSDF does not compromise productivity. Total and irrigation water productivity improved by 127.7 and 156.7%, respectively, under 100% RDP-2S over CA-FI-100% RDP-B. Residue retention further enhanced productivity, increasing grain yield by 14.0–15.0% and net returns by 26.4–27.5%. Post-harvest soil available P was 18.0 and 43.3% higher under SSDF than under CA-FI-100% RDP-B at 0–15 and 15–30 cm, respectively. The interaction of split P fertigation and residue retention was consistently superior for grain yield and water productivity. These findings establish 75–100% RDP delivered through split SSDF, combined with residue retention, as an agronomically superior, water-efficient, economically viable strategy for sustainable wheat intensification in the semi-arid IGPs.","在印度河-恒河平原（IGP）石灰性土壤上，常规地表撒施条件下的磷（P）管理面临严重的固定损失，导致磷利用效率（PUE）仅为10–25%，并造成小麦——一种全球重要的粮食安全作物——的产量差距。在中期保护性农业（CA）为基础的玉米-小麦-绿豆轮作体系中，开展了一项为期两年（2023–24和2024–25）的裂区田间试验，评估九种磷肥滴灌水平和分次施用方案通过地下滴灌施肥（SSDF）对小麦（品种HD 2967）生长、产量、水分生产力、经济效益、资源利用效率及收获后土壤有效磷的影响，并结合两种秸秆管理方式（还田：R+，不还田：R-）。处理包括：无磷（对照）、以DAP形式通过SSDF施用推荐施磷量（RDP；60 kg P₂O₅ ha⁻¹）的50%、75%和100%，分别以全部基施（播种后10天）或分次施用（播种后10天和25天），同时配合纳米DAP叶面喷施，并与常规保护性农业配合漫灌和基施撒施磷（CA-FI-100% RDP-B）进行比较。SSDF处理的总水分投入仅为178–275 mm，而漫灌条件下为437–452 mm。在SSDF处理中，100% RDP分两次施用（100% RDP-2S）在两年中均持续表现出最高的生长指标、籽粒产量（6.23和6.31 t ha⁻¹）和经济效益（BCR：1.8–2），较CA-FI-100% RDP-B分别提高籽粒产量10.6–11.5%和净收益13.7%。值得注意的是，75% RDP-2S在产量和盈利能力上与100% RDP-2S无统计学差异，表明在精准SSDF下减少25%的磷用量不会影响生产力。与CA-FI-100% RDP-B相比，100% RDP-2S处理下总水分生产力和灌溉水分生产力分别提高了127.7%和156.7%。秸秆还田进一步提高了生产力，使籽粒产量增加14.0–15.0%，净收益增加26.4–27.5%。收获后土壤有效磷在0–15 cm和15–30 cm土层中，SSDF较CA-FI-100% RDP-B分别高出18.0%和43.3%。分次磷肥滴灌与秸秆还田的交互作用在籽粒产量和水分生产力方面始终表现最优。这些研究结果表明，通过分次SSDF施用75–100% RDP并结合秸秆还田，是一种农艺上优越、水分高效、经济可行的策略，可用于半干旱印度河-恒河平原小麦的可持续集约化生产。","Frontiers in Sustainable Food Systems","2026-09-28T00:00:00Z","论文",80,{"impact":112,"substance":113,"depth":112,"authority":114,"freshness":115,"relevant":21,"comment":116},18,22,13,9,"两年田间试验证实分次地下滴灌施磷配合秸秆还田可减磷25%并显著提升小麦产量与水肥利用效率，数据扎实、结论可靠，对半干旱地区精准水肥管理有直接参考价值。",[118],{"name":107,"url":104},[120,121,122,29,53],"智慧农业","精准施肥","小麦",{"code":124,"slug":125,"name":122,"path":126,"parent_code":127},"A2","wheat","\u002Ftopic\u002Ffield-crops\u002Fwheat","A",[129,130],{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},{"code":38,"slug":39,"name":40,"path":41,"parent_code":42},{"status":44,"locked":14,"version":45,"method":46,"evidence":132},{"candidates":133,"agricultural_evidence":51},[134,140,144,149,156,162,169,176,182,186,192],{"code":31,"score":135,"supported":51,"title":136,"abstract":138,"tags":139},16,[137],"fertigation",[55,137],[53,121],{"code":124,"score":17,"supported":51,"title":141,"abstract":142,"tags":143},[125],[122,125],[122],{"code":38,"score":18,"supported":51,"title":145,"abstract":147,"tags":148},[146],"conservation agriculture",[146],[29],{"code":150,"score":99,"supported":51,"title":151,"abstract":152,"tags":155},"A3",[],[153,154],"玉米","maize",[],{"code":75,"score":99,"supported":51,"title":157,"abstract":158,"tags":161},[],[159,160],"粮食安全","food security",[],{"code":163,"score":99,"supported":51,"title":164,"abstract":165,"tags":168},"H2",[],[166,167],"土壤","soil",[],{"code":170,"score":99,"supported":51,"title":171,"abstract":172,"tags":175},"H3",[],[173,174],"灌溉","irrigation",[],{"code":177,"score":69,"supported":51,"title":178,"abstract":179,"tags":181},"A7",[],[180],"轮作",[],{"code":87,"score":69,"supported":51,"title":183,"abstract":184,"tags":185},[],[90],[],{"code":187,"score":69,"supported":51,"title":188,"abstract":189,"tags":191},"H7",[],[190],"干旱",[],{"code":193,"score":21,"supported":14,"title":194,"abstract":195,"tags":196},"I1",[],[],[120],[198,199],"地下滴灌 磷肥 小麦","保护性耕作 秸秆还田 小麦","地下滴灌磷肥小麦-3759","10.3389\u002Ffsufs.2026.1944629",{"doi":201,"openalex_id":203,"authors":204,"venue":107,"cited_by_count":252,"oa_url":104,"card":253,"direction":257,"ingested_from":259},"W7214579192",[205,207,210,212,214,216,218,221,223,225,227,229,231,234,236,238,241,244,247,250],{"name":206,"orcid":8},"Kadagonda Nithinkumar",{"name":208,"orcid":209},"Anchal Dass","https:\u002F\u002Forcid.org\u002F0000-0003-3909-1803",{"name":211,"orcid":8},"Devika A.

However, no clear pattern of CA's effect on greenhouse gas emissions exist, due to complex and interactive processes from CA's three main principles including appropriate fertilizer use as the fourth proposed principle of CA. Objective A comprehensive literature search was conducted to review evidence on the effect of CA's three main principles (reduced tillage, mulching, crop diversification) including appropriate fertilizer management on greenhouse gas (nitrous oxide–N 2 O, carbon dioxide–CO 2 , methane–CH 4 ) emissions. Methods We reviewed 422 out of 3452 publications to assess the relative strength of evidence on effects of reduced tillage, mulching and fertilizer management on greenhouse gas emissions, with an in-depth multi-study synthesis on crop rotation and experimental characteristics. Control treatments included conventional tillage, zero mulch, monocropping and standard mineral nitrogen (N) fertilizer application. Results and conclusions There was good (73%) and some (46%) evidence that reduced tillage practices reduce CO 2 and N 2 O emissions, respectively. There was some evidence that mulching increases N 2 O (46%) and CO 2 (55%) emissions while the effects of different fertilizer management strategies on greenhouse gas emissions were mixed. The multi-study analysis showed an association of nitrogen fertilizer category, N fertilizer rate and overall rotation type with CH 4 emission. However, the CH 4 distribution was highly inconsistent. Overall, continuous legume-legume rotation was associated with decreases in CO 2 compared to continuous cereal-cereal rotations. The cereal-cereal rotation up to and including the current crop was associated with an increase in CO 2 emission relative to a monocrop. Nitrous oxide was associated with the N fertilizer application rate with the medium N fertilizer rate (102–175 kg N ha −1 ) associated with increases in N 2 O compared to the zero N control. Significance Our study highlights the effect of CA's three main principles and appropriate fertilizer use on greenhouse gas emissions under different cropping systems and agroecological regions, and the need for standardised reporting to ensure continued importance of field experiments, particularly long-term experiments, in providing empirical evidence on impacts of agronomic practices on global environmental change.","背景 保护性农业（CA）因其在减缓气候变化等方面的潜在效益，在过去十年中受到关注。然而，由于保护性农业三项主要原则及其作为第四项拟议原则的合理施肥之间复杂的交互过程，保护性农业对温室气体排放的影响尚无明确规律。目的 本研究进行了全面的文献检索，以综述保护性农业三项主要原则（减少耕作、覆盖、作物多样化）及合理施肥管理对温室气体（一氧化二氮–N₂O、二氧化碳–CO₂、甲烷–CH₄）排放影响的证据。方法 我们从3452篇文献中筛选出422篇进行综述，以评估减少耕作、覆盖和施肥管理对温室气体排放影响的证据相对强度，并对作物轮作和试验特征进行了深入的多研究综合分析。对照处理包括常规耕作、无覆盖、单作和标准矿质氮（N）肥施用。结果与结论 有良好证据（73%）和一些证据（46%）表明，减少耕作措施分别降低CO₂和N₂O排放。有一些证据表明，覆盖增加了N₂O（46%）和CO₂（55%）排放，而不同施肥管理策略对温室气体排放的影响则好坏参半。多研究分析显示，氮肥类别、氮肥施用量和总体轮作类型与CH₄排放存在关联。然而，CH₄分布高度不一致。总体而言，与连续谷类-谷类轮作相比，连续豆类-豆类轮作与CO₂排放减少相关。与单作相比，截至并包括当前作物的谷类-谷类轮作与CO₂排放增加相关。一氧化二氮与氮肥施用量相关，中等氮肥施用量（102–175 kg N ha⁻¹）与零氮对照相比增加了N₂O排放。意义 本研究强调了保护性农业三项主要原则及合理施肥在不同种植制度和农业生态区域下对温室气体排放的影响，并指出需要标准化报告，以确保田间试验，特别是长期试验，在提供农艺措施对全球环境变化影响的实证证据方面持续发挥重要作用。","Agricultural Systems","2026-09-09T00:00:00Z",81,{"impact":112,"substance":113,"depth":112,"authority":50,"freshness":115,"relevant":21,"comment":271},"基于3452篇文献筛选422篇的保护性农业温室气体效应综述，方法扎实、结论具参考价值，但属学术综述而非产业级突破，适合作为专业精选。",[273],{"name":267,"url":264},[275,276,277,278,279],"温室气体","保护性农业","农业减排","施肥管理","免耕覆盖",{"code":281,"slug":282,"name":283,"path":284,"parent_code":285},"B7","protected-horticulture","设施园艺与植物工厂","\u002Ftopic\u002Fhorticulture\u002Fprotected-horticulture","B",[287,288],{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},{"code":38,"slug":39,"name":40,"path":41,"parent_code":42},{"status":44,"locked":14,"version":45,"method":46,"evidence":290},{"candidates":291,"agricultural_evidence":51},[292,298,303,307,312,318,324],{"code":281,"score":50,"supported":51,"title":293,"abstract":295,"tags":297},[294],"greenhouse",[296,294],"温室",[],{"code":31,"score":50,"supported":51,"title":299,"abstract":301,"tags":302},[300],"fertilizer",[55,300],[],{"code":38,"score":18,"supported":51,"title":304,"abstract":305,"tags":306},[146],[146],[276],{"code":177,"score":99,"supported":51,"title":308,"abstract":309,"tags":311},[],[180,310],"crop rotation",[],{"code":187,"score":99,"supported":51,"title":313,"abstract":314,"tags":317},[],[315,316],"气候变化","climate change",[],{"code":319,"score":69,"supported":51,"title":320,"abstract":321,"tags":323},"H6",[],[322],"农业生态",[],{"code":325,"score":20,"supported":14,"title":326,"abstract":327,"tags":328},"H4",[],[],[277,275],[330,331],"保护性农业 免耕覆盖 农业减排 施肥管理","保护性农业 免耕覆盖","保护性农业免耕覆盖农业减排施肥管理-2021","10.1016\u002Fj.agsy.2026.104909",{"doi":333,"openalex_id":335,"authors":336,"venue":267,"cited_by_count":252,"oa_url":264,"card":387,"direction":391,"ingested_from":259},"W7212036648",[337,339,342,344,346,349,352,355,357,359,362,364,367,369,371,373,375,378,381,384],{"name":338,"orcid":8},"Muneta G.
