Barley Grain Quality Under Drought Stress and Biological Treatments

This dataset documents a field study on the impacts of early drought stress and plant-based biologicals on spring malting and feed barley grain quality. The study evaluated four malting and four feed barley genotypes across two locations over three consecutive years. Analyzed grain traits include grain size, C/N ratio, crude protein content, and starch content.

Use Cases

• Analyze the effect of drought stress and biological treatments on crude protein content to assess suitability for malting versus feed.
• Model the relationship between grain size and C/N ratio under different stress and treatment conditions.
• Compare starch content stability across genotypes, locations, and years to identify resilient varieties.
• Investigate how the application of Giant knotweed biological influences the C/N ratio in both malting and feed barley.

Strengths

• Data is derived from a multi-year study conducted over three consecutive years.
• Experimental design includes eight distinct barley genotypes (four malting, four feed) tested at two field locations.
• Study investigates three key factors: drought stress, biological treatments (Cropcover, Giant knotweed), and genotype.

Limitations

• The dataset is contained within a 2.2 MB DOCX file, which may require parsing to extract structured, machine-readable data.
• Sample size is unknown as the number of experimental plots or data rows is not specified in the provided description.
• Geographic scope is limited to two unspecified field locations.
