Enhancing water productivity and yield of spring wheat through irrigation and planting density optimization under shallow-buried drip irrigation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Improving spring wheat production in oasis irrigation districts requires management strategies that reconcile high grain yield with efficient irrigation water use. Methods: A two-year field experiment was conducted in the Hexi Oasis, Northwest China, during 2024-2025 to evaluate the coupled effects of three planting densities (PD1, 10.0 million seeds ha Results: Grain yield was consistently maximized under PD3I1, reaching 8455 and 8796 kg ha-1 in 2024 and 2025, respectively, whereas PD2I2 achieved a more favorable balance between yield and water productivity. Compared with I1, I2 reduced grain yield by only 5.3% and 6.0% in 2024 and 2025, respectively, but increased WP Discussion: Overall, moderate planting density combined with moderate irrigation provided a practical strategy for sustaining yield while enhancing irrigation water productivity in arid oasis wheat systems, with the benefits being primarily attributable to improved management coordination rather than to novel physiological mechanisms.
