Effects of different intercropping systems on soil properties and tobacco yield and quality.

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
Intercropping is widely recognized as a sustainable practice for enhancing soil fertility and crop productivity. This study evaluated the effects of different intercropping systems on the physicochemical properties of tobacco-planting soil, nutrient uptake in tobacco plants, yield, and economic benefits to optimize tobacco cultivation. A two-year field experiment (2023-2024) was conducted in Midu and Weishan, Yunnan province, with five treatments: tobacco monoculture (TT), tobacco-buckwheat (TM), tobacco-soybean (TS), tobacco-peanut (TP), and tobacco-sweet potato (TH) intercropping. We measured soil nutrient levels and the nitrogen (N), phosphorus (P), and potassium (K) content in the roots, stems, and leaves of tobacco plants, and comprehensively evaluated leaf yield and sensory quality. The results indicated that the TS treatment significantly increased soil N and P availability and enhanced nitrogen accumulation in plants, elevating leaf N content by 71.43% compared to TT in 2024. The TM treatment improved potassium supply and increased P content in roots and K content in leaves. Economically, TS yielded the highest net return, which was 18.89% greater than TT, with benefit-cost ratios (BCR) of 1.75 (2023) and 1.78 (2024). Conversely, TH had the lowest BCR due to its higher production costs. Sensory evaluation revealed that TS produced tobacco with superior aroma quality and harmony, scoring closely to TT, while TM and TP resulted in a moderate aroma with slightly stronger irritation. In conclusion, the tobacco-soybean (TS) intercropping system demonstrated optimal performance in improving soil nutrient supply, promoting plant nutrient accumulation, and enhancing leaf quality and economic returns, showing high potential for widespread adoption.
