Agronomic performance of rootstocks on the juice grape ‘BRS Magna’ grown in a Brazilian se

A study measured the effect of seven grapevine rootstocks on the yield and quality of 'BRS Magna' juice grapes over six production cycles from 2015 to 2019 in Brazil. Variables evaluated include estimated yield, bunch characteristics, berry weight, and physical-chemical traits like soluble solids and acidity. The research was conducted by P. C. de S. Leão at the Embrapa Semiárido experimental field in Petrolina.

Use Cases

• Compare the yield performance of different grapevine rootstocks based on estimated yield and bunch count data.
• Analyze the relationship between rootstock and grape juice quality traits like soluble solids content and titratable acidity.
• Model the principal components of agronomic variables to separate rootstock performance across multiple production cycles.
• Assess the potential of specific rootstocks, such as 'IAC 572', for increasing grapevine yield in semi-arid conditions.

Strengths

• Data collected over six production cycles from 2015 to 2019, providing multi-year observations.
• Evaluates 11 specific agronomic and physical-chemical variables, including yield components and juice quality metrics.
• Reports a concrete yield increase of up to 61% (32.78 ton.ha-1) for a specific rootstock ('IAC 572').

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is absent; field semantics must be inferred from the research paper description.
• Data reflects a specific geographic and climatic context (Brazilian semi-arid region), which may limit generalizability.
