Chickpea Biostimulant Field Trials in Southern Italy, 2023-2025

A three-year field experiment in south Italy evaluated the effects of microbial and non-microbial plant biostimulants on chickpea under Mediterranean rainfed conditions. The dataset includes agronomic, physiological, qualitative, and spectral trait measurements across two genotypes and varying nitrogen fertilization rates. It was authored by Michele Andrea De Santis and published on figshare in June 2026.

Use Cases

• Predicting grain yield based on NDVI spectral measurements mentioned in the description.
• Analyzing the relationship between grain protein/phenolic content and post-flowering weather conditions.
• Modeling the effects of different biostimulant formulations on water use efficiency.
• Studying the survival variability of soil microbes under drought stress conditions.

Strengths

• Data spans three growing seasons (2023-2025), capturing marked seasonal variability.
• Includes measurements for grain yield, water use efficiency (reported +16 to +22%), protein content, and NDVI.
• Experimental design is factorial, combining two genotypes, two nitrogen rates, and three biostimulant types.

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 (244.8 KB), indicating a limited scope of raw data.
