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

Mineral and organic fertilizers differ in nutrient-release patterns and effects on soil biological processes, yet their combined influence on soybean productivity, seed composition, and soil biochemical functioning remains unclear. This study evaluated soybean and soil responses to mineral, farmyard manure (FYM), and combined fertilization over two growing seasons. A two-year field experiment was conducted in a randomized complete block design with three replicates. Eight fertilizer treatments, i.e., unfertilized control, triple superphosphate, 20-20 (20% N and 20% P₂O₅), 20-20 + urea, FYM + urea, and FYM at 40, 80, or 120 t ha⁻¹ were included in the study. Agronomic traits, chlorophyll index (SPAD), normalized difference vegetation index (NDVI), seed protein and oil contents, 100-seed weight, seed yield, soil enzyme activities, and soil NH₄⁺-N and NO₃⁻-N were recorded. Data were analyzed using linear mixed-effects models, and Tukey-adjusted pairwise comparisons were used to compare means. Fertilizer treatment significantly affected all plant and soil variables. The 20-20 + urea treatment produced the highest number of pods and nodes plant
