Sweet Corn Yield and Water Use Efficiency Under Drip Irrigation and Fertigation, 2019-2021

An experimental dataset from a two-year field trial in Hyderabad, India, examining the impact of drip irrigation levels and fertigation scheduling on high-density summer sweet corn. The data includes measurements of crop growth, cob and green fodder yields, total crop evapotranspiration, and crop water use efficiency. The study was authored by N. Lavanya and published on figshare under a CC-BY-4.0 license.

Use Cases

• Modeling the relationship between irrigation levels and sweet corn yield based on the described experimental treatments.
• Analyzing crop water use efficiency (CWUE) across different irrigation regimes as reported in the results.
• Estimating crop coefficient (Kc) values for sweet corn during different growth stages from the provided data.
• Comparing physical and economic optimum water requirements for sweet corn production under the described conditions.

Strengths

• Data is derived from a two-year experimental trial spanning the 2019–20 and 2020–21 growing seasons.
• Results include specific numerical ranges for key metrics, such as crop evapotranspiration (170.3 to 278.1 mm) and yields (up to 13,393 kg ha⁻¹).
• The study design includes multiple treatment levels for both irrigation (0.6, 0.8, 1.0 Epan) and fertigation (100% and 125% RDNK).

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 (775.9 KB), indicating a limited scope focused on a specific experimental trial.
