Assessing the impact of perennial groundcover and interseeded annual cover crops on maize yield and drainage water quality.

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
The low adoption of annual cover crops in the United States Corn Belt has motivated research into novel cover cropping systems that mitigate the degrading of water quality due to soil and nutrient loss without compromising corn (Zea mays L.) yield. This 3-year field study compared a Kentucky bluegrass (Poa pratensis L.) as a perennial groundcover (PGC), two interseeded annual cover crop systems (standard and wide-row), and a no-cover control for their effects on corn yield and subsurface drainage water quality. Each plot was monitored weekly for subsurface drainage flow and nutrient losses using a randomized complete block design with three replicates. The study occurred during a period of below-average precipitation, which caused strong year-to-year and seasonal variations in treatment performance. Treatment effects were most evident in the study's wettest year, when increased rainfall following a dry season caused a summer nitrate flush. During this high-leaching summer period, all cover crop systems reduced nitrate concentrations compared to the control. When averaged across the entire study, the high-biomass wide-row interseeded system reduced flow-weighted NO
