Weed Biomass and Rice Yield Data from Rainfed Low-Input Systems in Madagascar, 2016-2018

Two cropping seasons (2016/17 and 2017/18) of experimental data from the middle-west region of Madagascar. The dataset includes raw plot-level measurements of weed biomass, weed cover, weed surveys, rice yield, tiller number, and plant height. It was created by author Rafenomanjato, Antsa from the CIRAD Harvested Collection.

Use Cases

• Modeling the critical period of weed interference based on weed biomass and cover data.
• Analyzing the relationship between weed pressure and rice yield in low-input systems.
• Studying seasonal variation in weed competition and crop performance across two growing seasons.

Strengths

• Data covers two complete cropping seasons (2016/17 and 2017/18), allowing for seasonal comparison.
• Measurements are provided at the plot level, which is a standard unit for agricultural field experiments.
• Dataset includes multiple related variables: weed biomass, cover, surveys, and rice yield components.

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.
