Effect of inter- row spacing and seed rate on growth; Yield and yield components of fenugreek (Trigonella foenum - graecum L.) in Tehuledere district, Northeastern Ethiopia.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Fenugreek (Trigonella foenum-graecum L.) is well-adapted for growing in northeastern Ethiopia due to its ideal agro-climatic conditions. Despite its potential, limited research has been conducted in Ethiopia to improve the productivity of this orphan crop particularly regarding optimal row spacing and seed rate. The current study evaluated the effects of inter-row spacing and seed rate on growth, yield components, and grain yield of fenugreek. Field experiments were conducted from July 2022 to January 2023 at Kete and Korke kebeles in the Tehuledere district of northeastern Ethiopia. The experiment was conducted using a randomized complete block design with a factorial arrangement of five seed rates (15, 20, 25, 30, and 35 kg ha ⁻ ¹) and three row spacings (20, 30, and 40 cm) with three replications. Statistix 10.0 software was used to evaluate data on growth and yield components. The highest seed yield (0.98 t ha ⁻ ¹) was found at 20 cm row spacing with a seed rate of 30 kg ha ⁻ ¹, while the lowest yield (0.36 t ha ⁻ ¹) was found at 40 cm spacing with a seed rate of 15 kg ha ⁻ ¹, according to the results. To maximize fenugreek yield in the Tehuledere district and other similar agroecological areas, a row spacing of 20 cm and a seed rate of 30 kg ha ⁻ ¹are suggested. Further multi-season and multi-location studies are needed to validate the recommended seed rate and row spacing across varying agroecological conditions.
