Salt Tolerance of Taro and Yam Crops from Field Trials in Tonga

Data from two field experiments in Vaini, Tonga. For Experiment 1, one taro cultivar was grown under four irrigation salinity treatments. For Experiment 2, two yam cultivars were grown under two salinity treatments in rain shelters. The dataset includes measurements of fresh weights, dry matter, leaf characteristics, chlorophyll, stomatal conductance, nutrients, and soil salinity. It was authored by Harry Myrans and last updated on 2026-04-13.

Use Cases

• Modeling crop yield under saline conditions based on fresh weight and dry matter measurements
• Analyzing plant physiological responses to salinity based on stomatal conductance and chlorophyll data
• Comparing salt tolerance between taro and yam cultivars mentioned in the description
• Studying the relationship between soil salinity and plant nutrient uptake

Strengths

• Specific salinity levels are defined for treatments: groundwater (<1 dS/m), low salt (3–4 dS/m), and high salt (6–7 dS/m)
• Includes a diverse set of plant and soil measurements: fresh weight, dry matter, leaf traits, chlorophyll, stomatal conductance, and nutrients
• Data is from controlled field experiments with defined irrigation and shelter treatments

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 small at 47.1 KB, indicating limited scope
