Lupin Selenium Biofortification Field Trials in Southwest Spain, 2021-2023

Javier Matías's dataset documents a two-season field experiment (2021/22 and 2022/23) in Southwest Spain on selenium biofortification of three lupin species. It includes measurements of agronomic performance, grain nutritional composition, and selenium accumulation under four different selenium application rates. The dataset was last updated on 2026-05-26 and is shared under a CC-BY-4.0 license.

Use Cases

• Modeling the relationship between selenium application rates and grain selenium concentration based on the described linear increase.
• Comparing agronomic performance and protein content across different lupin genotypes (L. albus, L. angustifolius, L. luteus).
• Assessing the influence of seasonal variation on grain yield and nutritional composition as described in the results.

Strengths

• Includes specific quantitative results, such as grain yields (e.g., 2036.3 kg ha⁻¹ for L. albus) and protein content (e.g., 48.4% for L. luteus).
• Describes a controlled experimental design with a split-plot structure over two growing seasons.
• Focuses on a specific, timely research question regarding sustainable protein sources and nutritional enhancement.

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 (670.7 KB), indicating limited scope.
