The recent introduction in Brazil of production of quality seed potatoes in hydroponic systems, such as aeroponics, demands studies on the nutritional and crop management. Thus, this study evaluated the influence of electrical conductivity of the nutrient solution and plant density on the seed potato minitubers production in aeroponics system. The Agata and Asterix cultivars were produced in a greenhouse under tropical conditions (winter/spring). The experimental design was a randomized block in a split-split plot design. The plot consisted of 4 electrical conductivities of the nutrient solution (1.0; 2.0; 3.0; and 4.0 dS.m(-1)); the subplot, of 4 plant densities (25; 44; 66; and 100 plants.m(-2)); and the subsubplot, of the 2 potato cultivars (Agata and Asterix), totaling 4 blocks. The 2.2 and 2.1 dS.m(-1) electrical conductivities yielded the highest productivity of seed potato minitubers, for Agata and Asterix cultivars, respectively, regardless of plant density. For both cultivars, the highest yield was observed for the 100 plants.m(-2) density. (AU) | |
