Hierarchical modelling partitions variation in vineyard fruit maturity for optimal sampling

摘要

Background and Aims Sampling is problematic in perennial tree and vine crops because organ numbers are vast, budgets are low and maturation of fruit is asynchronous within and between individuals. Typically, the precision and the repeatability of sampling are low and methodologies used in the field vary widely within the industry. We define a combined statistical and cost model for fruit maturity sampling that could be applied widely and would enable precision and cost to be pre-defined.
