The presence of physiological abnormalities in garlic (Allium sativum L.) is one of the factors that cause the most reduction in crop yield. Garlic LSG is an anomaly of genetic and physiological causes characterized by the early sprouting of bulbils (cloves) before harvest. It is a characteristic that negatively influences the garlic culture, because, in addition to reducing commercial bulb yield, it depreciates the product, causing its market value to be compromised (Puiatti, 2017).
The roots homogeneously exploit the soil under ideal conditions for root development, and the soil volume is relatively greater than in soils with compaction problems (Valadão et al., 2015). Some compaction states cause changes in soil structure, resulting in increased soil density and soil RP (Cortez et al., 2018).
In an attempt to develop techniques of indirect measurement of soil attributes, apparent soil EC has been highlighted. One of its usefulness in agriculture stems from the fact that soil mass, with its variability in physicochemical composition, presents different levels of apparent soil EC (Machado et al., 2015).
In view of these facts, this research aimed: a) to analyze the variability of the studied attributes of the plant and the soil; b) define the linear and spatial correlations between plant and soil attributes; and c) to identify the best attributes that correlate spatially with GY and LSG for the elaboration of spatial variability maps.
