1 · What the graph read from it

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.

2 · The registry

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

This study aimed to investigate cultivar-specific responses to nitrogen and potassium fertilization in sugar beet (Beta vulgaris) to optimize yield, quality attributes, and fertilizer use efficiency. Five sugar beet cultivars (Indira, Carma, Mallak, Melodia, and Shantala) were evaluated under nine fertilization treatments combining three nitrogen and potassium levels (T1 (144 N,0 K); T2 (144 N,60 K); T3 (144 N,120 K); T4 (216 N,0 K); T5 (216 N,60K2);T6 (216 N,120 K); T7 (288 N,0 K); T8 (288 N,60 K); T9 (288 N,120 K)) in a split-plot design over two growing seasons (2020/2021 and 202120/22 ). Significant cultivar × treatment interactions (p < 0.001) were observed across all parameters. Root yield ranged from 55.72 t/ha (Indira) to 83.33 t/ha (Shantala under T2 treatment). Sucrose content varied from 18.10% (Indira) to 18.92% (Mallak), with corresponding purity levels of 79.93% and 76.39%. Principal component analysis revealed distinct cultivar-specific nutrient responses: lower nitrogen and potassium levels (T1 and T2) positively impacted quality attributes in Indira and Carma, while higher nitrogen and moderate potassium combinations (T3 and T6) enhanced yield attributes in Mallak and Shantala. Economic analysis showed optimal profitability with T3 treatment for Indira and Melodia (ROIs of 89.5% and 91.6%), T2 for Carma and Mallak (ROIs of 123.4% and 113.1%), and T1 or T6 for Shantala (ROI of 166%). Hierarchical clustering and correlation analysis identified strong positive relationships between root yield and biological yield (r = 0.94), recoverable sugar yield (r = 0.87), and sugar yield (r = 0.82). These findings provide valuable recommendations for cultivar-specific nutrient management strategies that farmers can implement to optimize both production efficiency and economic returns while reducing environmental impacts from excessive fertilization.
