This knowledge is essential for the biofortification of wheat with Zn. <em>Methods</em>: We analyzed Zn rhizo–mobilization, root morphology, Zn uptake, and the microbial composition in the rhizosphere and roots of four high–yielding wheat cultivars with contrasting grain Zn levels. The study was conducted under two P fertilizer rates, 0 and 44 kg P/ha, on the southern Loess Plateau, China. <em>Results</em>: Bacteria potentially alleviating P–Zn antagonisms, such as <em>Rhizobium</em> sp., <em>Sphingomonas</em> sp., and <em>Pseudomonas</em> spp., were specially enriched in H<sub>Zn</sub> cultivars with P application and demonstrated the ability to promote Zn rhizo–mobilization by decreasing soil pH, resulting in a 69.1 % increase in available Zn concentration. P application reduced root colonization by AM fungi <em>Diversispora densissima</em> in Low–Zn (L<sub>Zn</sub>) cultivars but not in H<sub>Zn</sub> cultivars, allowing H<sub>Zn</sub> cultivars to maintain higher root Zn acquisition efficiency. The P–induced increases in total root length and surface area per plant in H<sub>Zn</sub> cultivars were 40 % and 7 % higher, respectively, compared to L<sub>Zn</sub> cultivars, while the increase in average root diameter of H<sub>Zn</sub> cultivars was 62 % lower than that of L<sub>Zn</sub> cultivars. This suggests that the longer, thinner roots with larger surface areas were advantageous for H<sub>Zn</sub> cultivars in capturing more Zn from the soil. <em>Conclusion</em>: Therefore, recruiting more beneficial rhizobacteria, maintaining stable root colonization by AM fungi, and optimizing root growth are crucial strategies for H<sub>Zn</sub> cultivars to enhance shoot Zn uptake and mitigate P–Zn antagonism. <em>Implications or significance</em>: Combining high–Zn wheat with specific bacteria and fungi at the soil–root interface, along with appropriate P application, holds significant potential for achieving wheat biofortification with Zn.</div></div>","PeriodicalId":12143,"journal":{"name":"Field Crops Research","volume":"322 ","pages":"Article 109762"},"PeriodicalIF":5.6,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to optimize N management and enhance NUE in maize using the GreenSeeker™ (GS™) optical sensor, calibrated in conjunction with Nutrient Expert® (NE®). Field experiments conducted from 2012 to 2014 established a strong relationship between In-Season Estimated Yield (INSEY) at key growth stages (V<sub>2</sub>–V<sub>19</sub>) and maize yield, with R² values from 0.70 to 0.79.

The most effective strategy, NE® + 2-GS™, involved a basal N application per NE® guidelines and two split applications guided by GS™ at V<sub>7</sub> and V<sub>11</sub>. This approach improved grain yield by 22.4 %, enhanced agronomic efficiency (31.6 kg yield kg<sup>−1</sup> N applied), and increased NUE compared to state recommendations (SR). Additionally, NE® + 2-GS™ improved N energy use efficiency by 37.4 %, reduced greenhouse gas emissions by 21.0 %, and achieved a higher eco-efficiency index (0.19 US $ MJ<sup>−1</sup> and 1.03 US $ kg<sup>−1</sup>) than SR. The carbon footprint on a yield scale (CFy) was reduced by 48.2 %, indicating a substantial decrease in CO₂ emissions per economic yield unit. These findings support NE® + 2-GS™ as a feasible and environmentally sustainable strategy for efficient N management in maize.</div></div>","PeriodicalId":12143,"journal":{"name":"Field Crops Research","volume":"322 ","pages":"Article 109753"},"PeriodicalIF":5.6,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, soil health changes and its impacts on crop yield and resilient are poorly documented in tropical conditions. Thus, we aimed to i) evaluate the impact of biodiversification of soybean cropping system, using cover crops, on soil health and crop yield, and ii) evaluate the relationship of soil health with crop yield and resilience over time. A 5-year field study was carried out on a research farm within the Brazilian savannah biome, in a highly-weathered soil <em>Latossolo Vermelho</em> soil (Brazilian Soil Classification System), which corresponds to a Rhodic Hapludox in the Soil Taxonomy, to evaluate the effects of four alternative cropping systems where soybean was followed by cover crops and cash crop (maize). Eight soil health indicators (soil organic carbon (SOC), β-glucosidase activity, aggregate stability, bulk density, water-filled pore space, pH, P, and K contents) were measured, and a composite soil health index (SHI) was calculated for the 0–10, 10–20, and 20–30 cm layers. Additionally, soybean yield was measured to evaluate the relationship between soil health and crop yield. The results showed that the cover crop mix and ruzigrass after soybean enhanced soil biological health and overall SHI compared with maize and maize intercropped with ruzigrass at the 0–10 and 0–30 cm layers. Healthier soils were correlated with higher yields and resilience (lower coefficient of variation). SOC explained 20 % of yield changes, while β-glucosidase explained 35 % of yield resilience to climate-related stresses. We concluded that the biodiversification using cover crops (grasses or mix including grasses and legumes) improves soil health, soybean yield, and resilience to climate-related stresses. These findings provide a pathway to more sustainable, productive and climate-smart agricultural systems in tropical regions.</div></div>","PeriodicalId":12143,"journal":{"name":"Field Crops Research","volume":"322 ","pages":"Article 109755"},"PeriodicalIF":5.6,"publicationDate":"2025-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143128336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
