Highland Barley Fertilizer and Irrigation Treatments in Hexi, China

Hexi irrigation area in China hosts a two-year field experiment on highland barley. The dataset details the effects of reducing chemical nitrogen fertilizer and applying bio-organic fertilizer under different irrigation regimes on grain filling and yield. It was authored by Yinping Xu and last updated in 2026.

Use Cases

• Modeling grain yield based on fertilizer substitution rates and irrigation frequency.
• Analyzing grain filling characteristics under different water and nutrient management regimes.
• Comparing fertilizer partial productivity between chemical-only and bio-organic fertilizer blends.
• Optimizing water and fertilizer management plans for highland barley cultivation.

Strengths

• Data is based on a two-year field experiment, providing temporal replication.
• Specific treatment levels are defined, including 15% to 45% chemical fertilizer reduction and 30% to 90% bio-organic fertilizer application.
• Results include concrete metrics like grain dry weight, filling rate, and yield percentage increases (e.g., 7.48% yield increase in 2019).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 9.5 KB, indicating limited scope.
