PEREZ NARANJO, Juan Carlos; OSORIO VEGA, Nelson Walter  e  ALVAREZ LOPEZ, Claudia Lucia. GROWTH, PHOSPHORUS ABSORPTION AND ROOT MORPHOLOGY OF ASPARAGUS INOCCULATED WITH MYCORRHIZAL FUNGI AND FLUORESCENT PSEUDOMONAS. Rev. Fac. Nac. Agron. Medellín [online]. 2004, vol.57, n.2, pp.2373-2382. ISSN 0304-2847.

A greenhouse experiment evaluated the effects of phosphorus (P) application and inoculation with Glomus fistulosum and Pseudomonas aeruginosa on growth, root length, and P uptake of Asparagus officinalis grown on Alic Melanudand. Inoculation with G. fistulosum significantly increased shoot and root dry weight, primary and secondary root lengths, and plant P uptake. Phosphorus application significantly increased extractable P in the soil (Bray II), but despite this increase, there was no significant increase in plant growth. Inoculation with P. aeruginosa had no significant effect on the variables studied, nor were there significant interactions among the factors.
