Garlic (Allium sativum L.) is an essential vegetable in human food, and its production chain is a source of job and income generation for the producer. Garlic plant variables, such as total plant mass, floral tassel length, leaf length, leaf width, number of leaves, dry mass, pseudostem diameter, number of cloves, mass of clove, and root mass, were studied by Oliveira et al. (2020a). These authors point out that these surveys can provide crop status and essential information about the activities developed, mainly in the context of attention to crop management.
The positive spatial autocorrelation of the studied attributes can be understood when the higher or lower values are grouped in a point or location. However, when the spatial autocorrelation is negative, there is a dissimilarity between the attributes in space (Anselin et al., 2006; Neves et al., 2015).
The spatial distribution analysis of indicators is an instrument that can contribute to the understanding of the processes involved in a given phenomenon that is to be studied, allowing the analysis of characteristics and differences of each territorial space, beyond the simple geographical view, covering the production space (Oliveira et al., 2020b).
Given the importance of knowing the reality of each point of the field concerning the performance of the crop, especially about the productivity of the garlic crop, exploratory studies that use data from production components must be carried out. Therefore, this study aimed to analyze the spatial autocorrelation of irrigation concerning the other productive components of the garlic crop.
