Biochar enhances seed germination and crop early growth for sustainable agriculture in Bangladesh.
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
Biochar (BC) application to low-fertility soils enhances crop yield, soil quality, and sustainable agricultural production. Although many studies have explored the effects of biochar on tropical crops, research specific to Bangladesh is limited. Given the agrarian system in Bangladesh, dense population, and vulnerability to climate change, adopting sustainable agricultural practices is essential. This study evaluates the impact of different biochar dosages on the germination and early growth of five major crops Oryza sativa (rice), Triticum aestivum (wheat), Capsicum annuum (chili), Solanum melongena (eggplant), and Solanum lycopersicum (tomato) using Acacia auriculiformis wood-waste biochar. The research was conducted using a randomized complete block design (RCBD) in a nursery setting. Biochar treatments of 10 t/ha and 15 t/ha were applied, with assessments made of germination (%), germination rate (after 7 days), shoot height (cm), root height (cm), leaf number, and root-shoot dry weight ratio. The results indicated a significant (p < 0.001) increase in germination (%) with higher biochar application rates. The linear mixed-effects model showed a significant effect of biochar treatment on germination (%) (F = 57.33, p < 0.001) and a significant interaction with crop type (F = 15.84, p < 0.001). In C. annuum, the 15 t/ha treatment resulted in a 96% increase in germination compared to the control (43.3 ± 1.08% vs 85.1 ± 2.15%). Similarly, in O. sativa, germination was significantly higher with the 10 t/ha (84.5 ± 1.52%) and 15 t/ha (91.8 ± 1.49%) treatments compared to control (59.3 ± 2.38%). Biochar significantly (p < 0.05) influenced early germination rates (after 7 days) and early growth parameters (e.g., shoot length, leaf count, root-shoot ratio), with the 15 t/ha treatment showing substantial improvements for C. annuum and O. sativa, while no significant effects were observed for S. lycopersicum. These findings underscore the potential of A. auriculiformis in enhancing germination and early growth of economically important crops, highlighting its role in promoting sustainable agriculture in Bangladesh.
