Optimizing split-fertilizer applications for enhanced maize yield and nutrient use efficiency in Nigeria's Middle-belt.

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
Inadequate and imbalanced fertilizer application is a significant barrier to achieving higher maize yields in Nigeria's Middle Belt. This study hypothesized that optimizing fertilizer types and application rates, particularly through split applications of straight fertilizers, can significantly enhance maize yield and nutrient use efficiency compared to conventional NPK blends and farmer's practices. This experiment evaluated the effects of optimizing types and amounts of fertilizer on maize growth and yield, soil characteristics, and nutrient use efficiencies in the mid-belt region of Nigeria. A field experiment was conducted at two locations using a randomized complete block design with four replications. The treatments included national and regional fertilizer recommendations, applied as NPK blends and straight fertilizers, along with a farmer's practice and control. Soil samples were collected before and after the experiment, and data on yield, yield attributes, grain, and leaf samples, were collected for analysis. The results showed that split applications of straight fertilizers increased grain yield by 22 %-46 %, achieving yields ranging from 2.37 to 3.08 t ha
