VILLAVICENCIO GUTIERREZ, Eulalia Edith et al. Mineral nutrition with nitrogen, phosphorus and potassium in the production of blue barrel in greenhouse. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.spe23, pp.313-323.  Epub 20-Nov-2020. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v0i23.2030.

In the biznaga ‘blue barrel’ (Ferocactus glaucescens (DC.) Britton and Rose) 12 treatments were evaluated considering nutrient concentrations (100, 200, 400 and 800 mg L-1) of soluble fertilizers in interaction with three nitrogen levels (N), phosphorus (P) and potassium (K) (100-50-50, 100-50-100 and 50-50-100), these were compared with the nutrient solution of Steiner at 25% and 50% and two commercial controls (triple 17 and triple 20). The variables evaluated were plant height, stem diameter, fresh and dry weight of stem and root, and concentration of N, P and K. An ANOVA and Tukey’s mean test (p≤ 0.05) were performed, indicating that the 50% Steiner nutrient solution and the solution prepared with 800 mg L-1 with the balance of 100-50-100 of NPK generated at 153 DDT plants with higher biomass and commercial size with stem height and diameter greater than 6 cm referring that in early stages the N:K relationship influence this process.
