In the year 2014, in Mexico, 355 hectares of Porophyllum ruderale were harvested. Recently, this leafy vegetable has gained importance due to its nutraceutical properties. However, scarce information is available regarding their mineral nutrition. The objective was to evaluate the effect of four concentrations of the Steiner nutrient solution (1.0, 1.5, 2.0, and 2.5 dS·m-1 of EC) on the yield of P. ruderale. The experiment was set up in a greenhouse with plastic cover located at 18º 58’ 51’’ NL, 99º 13’ 55’’ WL and a height of 1866 m; in Cuernavaca, Morelos, Mexico. The substrate was mix BM2 Berger® and pots of six inches were used. The sowing was done on May 25, 2015; respectively. The yield (fresh weigth of aerial biomass) 53 days after sowing was evaluated. With 1.5 dS·m-1 of EC of Steiner nutrient solution the highest yield per plant (66.4 g) was obtained.
