Allelopathic and autotoxic effects of sorghum extract and residues on seed behavior, and morphological, physiological, and biochemical responses of several plants.

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
This study investigated the allelopathic potential of sorghum (Sorghum bicolor L.) by applying aqueous extracts (0, 2, 4, 6, and 8%), root residues, and burned root residues to eight crop species (sorghum, corn, wheat, barley, sunflower, rapeseed, alfalfa, and cowpea) under PEG-6000-induced drought stress (20% PEG) using a two-phase design (in vitro and greenhouse). In the petri dish experiment, sorghum derivatives caused clear, concentration-dependent reductions in germination indices, seedling growth, biomass accumulation, and biochemical attributes, including photosynthetic pigments, proline, soluble carbohydrates, and antioxidant enzyme activities (CAT, SOD, and APX). Alfalfa and cowpea showed the highest sensitivity to the combined allelopathic and osmotic stress and were excluded from the greenhouse assay. During the greenhouse phase, species-specific tolerance patterns emerged: sorghum showed the greatest resilience to root residue treatments under drought conditions, while the remaining crops displayed varying degrees of susceptibility. Overall, the findings demonstrate strong dose-responsive allelopathic effects of sorghum across laboratory and greenhouse conditions, highlighting its potential for sustainable weed management and crop rotation systems, while underscoring the importance of interspecific variation in plant tolerance to drought stress.
