Soilless culture as a novel strategy for maximizing growth performance and fiber yield in industrial hemp (Cannabis sativa L.).
Article in BMC plant biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundHemp (Cannabis sativa L.) is one of the oldest cultivated plants in human history. It is a valuable plant that has economic value for all industrial branches. The hemp plant has fibers of the highest quality. Accordingly, research aiming to enhance the fiber yield of hemp has significant agronomic and industrial relevance.
methodsTo this end, three soilless media treatments were applied to the modified Hoagland solution. The effects of N: P:K/255:45:267 (A1), A1 + 10 mg/L silicon (A2), and A1 + 1 mg/L indole butyric acid (A3) on plant growth and fiber yield were investigated in Narlı hemp (Cannabis sativa L.), a registered local variety (Türkiye), in deep water culture and soil media (A4).
resultsThe analysis determined that the soilless medium was more productive than the soil medium in terms of root fresh-dry weight, stem fresh-dry weight, stem length, stem thickness, leaf length and width, relative water content (RWC), photosynthetic pigment content, fiber content, and total cellulose content. According to these results, the lowest values were obtained in the soilless medium in terms of malondialdehyde (MDA) and leaf secondary metabolite (cannabidiol: CBD, tetrahydrocannabinol: THC, and cannabinol: CBN) contents, which indicate stress in the plant. CBD was measured %0.0213, %0.0134, %0.0395, %0.0326, THC was measured %0.002, %0.0017, %0.0032, %0.0033, CBN was measured %0.0003, %0.0002, %0.0002, %0.0009 (A1, A2, A3, A4 respectively). Considering all the parameters studied, the hemp plant grown in the deep water culture medium containing Si yielded the best results among the treatments. The fiber content was 29.12% in A2, 24.02% in A1, 19.99% in A4, and 13.74% in A3. The cellulose content was determined to range from 61% to 82% on average in the treatments tested. The highest total cellulose content of 82% was obtained from treatment A2.
conclusionThe current study revealed that silicon (Si) treatment significantly increased fiber and cellulose contents. Incorporating such treatments into production models is regarded as a cost-effective and efficient strategy.
