Abstract

The selection of varieties is extremely important for decreasing fertilizer consumption. However, little attention is devoted to assessing the effectiveness of row spacing in tandem with types of varieties of pea on root development in the context of limited nutrition. As essential knowledge in this area is lacking, a study was conducted with two objectives using an ordinal regression model. (i): To determine whether qualitative variables (cultivar, fertilization, and row spacing) or quantitative variables (root parameters) affect the root dry mass density, and (ii): To assess the variation in root architecture of two pea cultivars (fodder vs. edible type) grown under different P supply levels (0, 45, and 90 kg P2O5) and row spacing (narrow—15 cm—and wide—30 cm). The ordinal regression model showed that row spacing and cultivar type are meaningful predictors of root dry mass density (RDMD). The root dry mass density increased at wider row spacing in the fodder pea cultivar. As root surface area density (RSAD) and SRL-specific root length (SRL) most accurately describe root mass, it was concluded that the cultivar type and row spacing are crucial factors for increasing root plasticity, which can improve soil utilization.
