Climate-adapted variety selection and optimal planting density for improving maize yield in the Guanzhong region, China.

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
backgroundSuboptimal densities and regional environmental heterogeneity often constrain maize yield intensification. Increasing planting density and selecting climate-adapted varieties are therefore critical for improving grain yield.
resultsThe study was conducted at 33 sites in the Guanzhong region from 2017 to 2021, addressing uncertainty in density-variety selection for local maize production. Six varieties (including widely grown and newly introduced types) were tested at four planting densities (45 000-90 000 plants ha
conclusionUltimately, these findings provide a practical yield-enhancement strategy, offering useful references for transforming low-productivity fields into high-yield systems in similar monsoon-influenced rotation zones worldwide. © 2026 Society of Chemical Industry.
