Assessment of fertilizer prescription equations, crop and soil performance with different nutrient management practices for green gram (Vigna radiata) in Southern India's Alfisols.
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 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
The effect of fertilizers application based on "fertilizing the soil versus fertilizing the crop" which ensure real balance between the applied and available soil nutrient is urgently needed. Hence, the present study was conducted during two consecutive crop seasons (Kharif 2022 and Kharif 2023) to assess the effect of imbalanced and balanced fertilization based on initial soil test values and targeted yields, and to determine the effect of different approaches of nutrient recommendation on soil quality, nutrient acquisition, and yield of green gram. The eight fertilizer treatments were laid out in a randomized block design with three replications. The results revealed that STCR integrated approach showed seed yield increases of 41.07% and 55.24% over GFRD, and 54.90% and 64.65% over SFR in 2022 and 2023, respectively. Similarly, root nodules per plant increased by 17.41% and 20.78% over GFRD in 2022 and 2023, respectively. The STCR approach for different yield targets also showed significant improvements in nutrient uptake and value cost ratio (VCR). Utilizing the principal component analysis, the soil quality index effectively reflected the impact of nutrient management on soil properties, with the STCR-integrated application showing the highest correlation with improved soil physical and chemical properties.
