Crop steering through osmotic stress can reduce height but reduced yield in medical Cannabis.
Article in Journal of cannabis research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPrecision water stress, achieved via osmotic stress, has the potential to control plant size and improve crop quality without reducing yield, but results across species and cultivars have been inconsistent.
methodsThis study examined the effects of elevated salinity on two diverse Cannabis sativa cultivars, Trump and Cherry. One group (control group) was grown at 4 mS cm⁻¹ (-0.14 MPa), one group at 8 mS cm⁻¹ (-0.28 MPa), and a third (hybrid) group at 8 mS cm⁻¹ (to reduce vegetative growth) until flowering and then reduced to 4 mS cm⁻¹ to minimize effect on flower yield.
resultsPlant height was reduced 15% in both the high and hybrid treatments. Flower yield decreased by 20% in cv. 'Trump' in the hybrid treatment, but the decrease in yield in the high salinity treatment was not statistically significant. In cv. 'Cherry', flower yield declined by approximately 20% in both the constant high salinity and hybrid treatments. There was no difference in cannabinoid concentrations among treatments in either cultivar.
conclusionsThese findings indicate that Cannabis sativa is highly tolerant to osmotic stress, but the response varies by cultivar. It is difficult to reduce plant size without reducing yield. There is no evidence that increased salinity altered cannabinoid concentration.
