<p>Research data.</p>

Yinping Xu's research data, last updated May 2026, examines the effects of reducing chemical nitrogen fertilizer and applying bio-organic fertilizer on highland barley. The dataset, 308.5 KB in size, contains results from a two-year field experiment in the Hexi irrigation area of China, comparing different irrigation and fertilization treatments. It likely includes measurements of grain dry weight, filling rate, fertilizer partial productivity, and yield.

Use Cases

• Modeling the relationship between bio-organic fertilizer application rates and highland barley yield based on described treatments.
• Analyzing the impact of deficit irrigation on grain filling duration and dry weight as described in the experiment.
• Comparing fertilizer partial productivity across different combinations of chemical and bio-organic fertilizer reductions.
• Investigating the interaction between irrigation frequency and fertilization strategy on crop performance.

Strengths

• Data is based on a two-year field experiment, providing temporal replication.
• The description specifies concrete treatment levels (e.g., fertilizer reduced by 15%, 30%, 45%; bio-organic fertilizer increased by 30%, 60%, 90%).
• Results include specific percentage yield increases (7.48% in 2019, 7.06% in 2020) under certain conditions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (308.5 KB), indicating a limited scope.
