Optimized planting density enhances cotton yield in cotton-peanut intercropping via improved photosynthesis and dry matter partitioning.

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
Intercropping and increased planting density are important agronomic strategies to alleviate the conflict between grain and cotton production and to improve land use efficiency. Cotton-peanut intercropping can enhance the land equivalent ratio (LER), and appropriate planting density is critical for achieving high yields. However, the effects of increased density on the photosynthetic characteristics and yield of intercropped cotton in the arid region of southern Xinjiang remains unclear. To address this issue, a field experiment was conducted in southern Xinjiang during 2024-2025 using a split-plot design. The main plots included planting patterns: monocropped cotton (MC), cotton-peanut intercropping IC, and monocropped peanut (MP), while subplots consisted of three planting density (D1: 180, 000 plants·ha
