Trotter). A key teff cultivar with brown grains was used as the plant material. Experiments were conducted in a split-plot design with four replications over 2 years. Irrigation, nitrogen, years, and irrigation × nitrogen interactions were found to be significant for all parameters investigated (<i>p</i> &lt; 0.01).</p>\u0000 <p><b>Results</b>: Over 2 years, irrigation water requirements ranged from 340 mm in the I₅₀ × N₀ treatment to 603 mm in the I₁₀₀ × N₉₀ treatment. The highest irrigation water use efficiency (IWUE; 0.69 kg m⁻³) was observed in the I₅₀ × N₆₀ treatment, while the lowest (0.31 kg m⁻³) was observed in the I₁₀₀ × N₀ treatment. Similarly, crop water productivity (CWP) ranged from 0.29 kg m⁻³ (I₁₀₀ × N₀) to 0.52 kg m⁻³ (I₇₅ × N₆₀). For grain yield and components, the greatest grain yield was obtained from I₇₅ × N₆₀ treatments (2.52 t ha⁻¹), the greatest biological yield was obtained from I₁₀₀ × N₉₀ treatments (6.83 t ha⁻¹), the greatest harvest index was obtained from I₅₀ × N₆₀ treatments (26.01%), and the greatest thousand grain weight was obtained from I₇₅ × N₆₀ treatments (29.39 mg). Increased irrigation levels reduced crude protein content but increased crude ash and phytic acid, causing variations in resistant and total starch. Higher nitrogen doses raised crude protein, crude ash, and resistant starch while reducing phytic acid and amylopectin. The N₉₀ dose provided the highest resistant starch, and the I₅₀ × N₉₀ combination yielded the highest amylose content. Irrigation and nitrogen significantly impacted starch and amylose ratios.</p>\u0000 <p><b>Conclusion</b>: For optimal grain yield, biological yield, and quality, the I₇₅ × N₆₀ combination is recommended, as it enhances resistant starch, biological yield, and thousand-grain weight while maintaining balance in plant height and total starch content.</p>\u0000 </div>","PeriodicalId":16802,"journal":{"name":"Journal of Plant Nutrition and Soil Science","volume":"189 4","pages":"518-529"},"PeriodicalIF":3.3,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148662485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three treatment variants were tested against reference variant: compressed air (CA), compressed air with injection of granules (CA+G), and compressed air followed by water injection (CA+W). Soil structure and tree morphological traits were monitored over 2 years after soil treatment. In addition, the soil surface was scanned using a terrestrial laser scanner (TLS) before and after the treatment.

The sand site exhibited the greatest surface uplift and pore volume increase (19.8 dm³ within a 0.8 m radius around the injection point), followed by silt (12.5 dm³) and clay (8.3 dm³). The CA and CA+G treatments produced pore volumes two to three times greater than those generated by the variant with water injection (CA+W). However, most soil parameters, including bulk density, gas diffusion, and root density, showed only marginal or inconsistent improvements. Tree structural parameters showed no improvement in any treatment compared to the reference. Moreover, crown development nearly stagnated in treated trees, particularly under the CA+W treatment. Overall, the treatment failed to produce sustained improvements in soil or tree structure parameters. Due to its limited efficacy and high cost, pneumatic lance injector treatment cannot be recommended in its current form without significant methodological optimization.</p>\u0000 </section>\u0000 </div>","PeriodicalId":16802,"journal":{"name":"Journal of Plant Nutrition and Soil Science","volume":"189 4","pages":"605-620"},"PeriodicalIF":3.3,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jpln.70080","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148662632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
