Maize Yield and Photosynthesis Data from Oasis Irrigation Experiments, 2022-2024

The Hexi Oasis irrigation area in China was the site for a field experiment conducted from 2022 to 2024. The dataset likely contains measurements of maize grain yield, photosynthetic physiology parameters, and C4 enzyme activities under varying tillage, cropping patterns, and irrigation regimes. It was authored by Congcong Guo and is available under a CC-BY-4.0 license.

Use Cases

• Analyze the impact of no-tillage versus conventional tillage on maize yield based on the described experimental treatments.
• Model the relationship between irrigation levels and photosynthetic performance metrics like net photosynthetic rate and stomatal conductance.
• Compare grain yield stability in intercropping versus monocropping systems under water-limited conditions.
• Study the regulation of key C4 enzymes (e.g., PEP carboxylase) and their gene expression in response to different agricultural practices.

Strengths

• Experimental design systematically evaluates three factors: tillage, cropping pattern, and irrigation regime.
• Results include specific percentage increases in grain yield (e.g., 27.2%) and enzyme activity increases (6-14%) for key treatments.
• Data covers a multi-year study period from 2022 to 2024.

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 stored as a DOCX file (725.4 KB), which suggests the primary data may be embedded within a document rather than in a standard tabular format.
