Abstract

Dryland agriculture is vital to global crop production and food security, with conventional tillage (CT) traditionally dominating rain-fed systems. However, no-tillage (NT) practices are increasingly being adopted as a sustainable alternative to enhance crop productivity and long-term environmental resilience. This meta-analysis compared the effects of NT with CT on dryland winter wheat (Triticum aestivum L.) yield, water use efficiency (WUE), and nitrogen use efficiency (NUE) across varying nitrogen fertilizer (NF) levels (low < 100 kg N ha⁻¹; medium ¹00–200 kg N ha⁻¹; and high > 200 kg N ha⁻¹), mulching methods, and cover crop practices. The meta-analysis presented that the interaction of NT with straw mulching, leguminous cover crops (LCC), and residue retention increased the dryland winter wheat grain yield by 48, 44, and 31 %, respectively, along with WUE by 57, 47, and 27 %, and NUE by 46, 58, and 37 % for the medium-NF, compared to the CT. Non-leguminous cover crops (NLCC) increased the yield, WUE, and NUE under high-NF than low-NF. Residue removal with low-NF under NT had an insignificant impact on yield, NUE and WUE. However, residue removal increased these parameters under medium and high-NF. Increasing the rate of NF did not increase the yield, NUE, and WUE under such interactions. The effects of tillage with management practices on wheat grain yield, WUE, and NUE also varied with soil and climatic conditions. We demonstrate that NT integrated with mulching and LCC can significantly enhance wheat yield, WUE, and NUE at medium-NF level in fine and medium-textured soils, offering a sustainable alternative to conventional tillage and reducing dependency on high nitrogen inputs in dryland winter wheat cropping systems.

农艺措施对全球旱地冬小麦产量、水分利用效率和氮利用效率的长期影响：一项荟萃分析

旱地农业对全球作物生产和粮食安全至关重要，传统耕作（CT）传统上主导着雨养系统。然而，免耕（NT）的做法越来越多地被采用为一种可持续的替代方案，以提高作物生产力和长期的环境适应能力。本荟萃分析比较了不同氮肥水平（低氮肥、低氮肥、低氮肥、低氮肥、低氮肥、低氮肥、低氮肥、低氮肥、低氮肥、低氮肥、低氮肥）对旱地冬小麦（Triticum aestivum L.）产量、水分利用效率（WUE）和氮利用效率（NUE）的影响。 100公斤N 公顷−1;中100-200 kg N ha−1；和高>；200 kg N ha−1)，覆盖方法和覆盖作物做法。荟萃分析表明，与秸秆覆盖、豆科覆盖作物（LCC）和残茬保留互作相比，氮肥与秸秆覆盖的互作使旱地冬小麦产量分别提高了48%、44%和31% %，WUE提高了57%、47%和27% %，NUE提高了46%、58%和37% %。非豆科覆盖作物在高氮肥条件下比低氮肥条件下提高了产量、水分利用效率和氮肥利用效率。低纳滤除渣对产量、氮肥利用效率和水分利用效率影响不显著。而在中、高纳滤比条件下，除渣使这些参数增加。在这种相互作用下，增加NF的速率并没有增加产量、氮肥利用效率和水分利用效率。耕作与管理措施对小麦产量、水分利用效率和氮肥利用效率的影响也因土壤和气候条件而异。研究表明，在细土和中等质地土壤中，氮肥与覆盖和低氮覆盖相结合可以显著提高小麦产量、水分利用效率和氮肥利用效率，为传统耕作提供了一种可持续的替代方案，并减少了旱地冬小麦种植系统对高氮投入的依赖。

期刊介绍： Soil & Tillage Research examines the physical, chemical and biological changes in the soil caused by tillage and field traffic. Manuscripts will be considered on aspects of soil science, physics, technology, mechanization and applied engineering for a sustainable balance among productivity, environmental quality and profitability. The following are examples of suitable topics within the scope of the journal of Soil and Tillage Research: The agricultural and biosystems engineering associated with tillage (including no-tillage, reduced-tillage and direct drilling), irrigation and drainage, crops and crop rotations, fertilization, rehabilitation of mine spoils and processes used to modify soils. Soil change effects on establishment and yield of crops, growth of plants and roots, structure and erosion of soil, cycling of carbon and nutrients, greenhouse gas emissions, leaching, runoff and other processes that affect environmental quality. Characterization or modeling of tillage and field traffic responses, soil, climate, or topographic effects, soil deformation processes, tillage tools, traction devices, energy requirements, economics, surface and subsurface water quality effects, tillage effects on weed, pest and disease control, and their interactions.
