Effects of cold plasma seed treatment on pea (Pisum sativum L.) plant performance under drought and well-watered conditions.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Cold plasma (CP) technology is an emerging technology with the potential to enhance agricultural productivity and sustainability. Although its application in crop production is still in the early stages, CP seed treatment has demonstrated promise in improving various growth parameters, especially in legumes. We hypothesized that CP seed treatment can improve nodulation, symbiotic nitrogen fixation (SNF), root and shoot growth, overall productivity, and drought stress resistance in field pea. A controlled environmental study was conducted to investigate the effects of dielectric barrier discharge-generated CP seed treatment for 6 min on yellow field pea under different moisture regimes [30%, 45%, 60%, and 75% field capacity (FC)], focusing on nodulation, and root and shoot growth parameters at the flowering stage. Based on experiment-1 findings, 30% and 75% FC were selected as drought and well-watered conditions, respectively, to study the effect of CP seed treatments on SNF parameters at the flowering stage and nitrogen fixation, yield, and seed quality parameters at maturity. CP seed treatment improved root growth parameters at the flowering stage and an increasing trend was observed for shoot and nodulation parameters across different moisture levels. As an independent factor, moisture stress negatively affected nodulation and shoot growth parameters at the flowering stage. CP seed treatment improved nitrogen fixation and yield parameters under well-watered conditions compared to drought conditions at seed maturity. However, the seed protein content or the quality was not improved by the CP seed treatment. Grain yield, yield parameters, grain nitrogen, and nitrogen fixation were reduced under drought stress compared to the well-watered condition. Therefore, these findings underscore the potential of CP to enhance crop performance in well-watered conditions. The underperformance of the CP-treated seeds at drought conditions is not well understood and warrants further investigation.
