Potato Growth and Yield Data Under Varying Irradiance and Temperature

Phytotron experiments on the Scandinavian potato cultivar Gullauge measured the effects of four irradiance levels and three constant temperatures on development, growth, and yield. The dataset, authored by Jørgen Mølmann and last updated in 2026, includes results from two separate growing seasons in 2020 and 2021. Findings indicate that high irradiance becomes increasingly critical for potato growth at low temperatures, relevant for high-latitude agriculture.

Use Cases

• Modeling potato yield response based on irradiance and temperature interactions described in the study.
• Analyzing the trade-off between vegetative development time and tuber dry matter content under controlled conditions.
• Studying the effects of low solar elevation and temperature on crop physiology for high-latitude agriculture.
• Training predictive models for shoot biomass and plant height using the experimental factors of light and heat.

Strengths

• Data is derived from controlled phytotron experiments, allowing for precise manipulation of environmental variables.
• Experiments were conducted over two separate seasons (2020 and 2021), providing some temporal replication.
• Specific treatment levels are documented, including irradiance levels between 80–215 µmol/m2/s and constant temperatures of 9, 15, 18, and 21 °C.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Description metadata is limited; actual data quality requires manual inspection after download.
