Influence of exogenously applied k-carrageenan at various concentrations on plant growth, phytochemical content, macronutrients, and essential oils of Ocimum basilicum.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Food safety and security are now among the most urgent problems to be resolved as the world's population continues to grow. Intensive agriculture is required to meet the demands of a growing population and guarantee greater agricultural yield. Chemical pesticides and fertilizers are an essential part of intensive farming. Their extensive use accelerates the depletion of other important and minor nutrients, resulting in poor soil fertility and nutritional imbalance. There are serious health and environmental hazards associated with several of these hazardous agricultural chemicals. In context, for the first time, this study represents an innovative experiment exploring the impact of exogenously applied k-carrageenan on plant growth, physiological parameters, phytochemical content, macronutrients, and essential oil percentage in Ocimum basilicum plants. The investigation assessed the effect of varying k-carrageenan levels; 0.30, 0.60, 0.90, and 1.20 mM versus untreated control. The findings revealed that all k-carrageenan treatments significantly enhanced growth indicators compared to the control. The phytochemical analysis demonstrated that foliar application of k-carrageenan, particularly at 1.20 mM, significantly enhanced total chlorophyll, chlorophyll a, chlorophyll b, and total carbohydrate and essential oil percentage compared to the untreated control. O. basilicum essential oils show rich, nuanced flavors with higher levels of Methyl cinnamate, Camphor, trans-methyl cinnamate, Eucalyptol, Linalool, and β-Caryophyllene among treatments. Treatment effects were also observed in the macroelements content of Nitrogen (N), phosphorus (P), and potassium (K). k-carrageenan-induced alterations were noted in the contents of essential oil compounds. These results suggest that k-carrageenan can be a growth-promoting agent and significantly enhance essential oil yield, particularly in O. basilicum plants.
