Vesicular arbuscular mycorrhizal Glomus intraradicesAzospirillum brasilense and Brasinoesteroid on yield of maize in luvisol soil. Fungod de Aceptado: In the state of Yucatan more than thousand hectares are planted with maize and the average yield is 0.

Most of the planted area is under rainfall conditions; therefore maize production and its sustainability depend solely on precipitation.

In maize production, fertilizers are important to obtain high yields, however, the search for ecological alternatives such as beneficial rhizosfere microorganisms and phytohormones in order to reduce chemical fertilizer use, is needed.

The aim of this study was to compare the use of mycorrhiza VAM Glomus intraradicesAzospirillum brasilense and a Bassinosesteroidal phytormone with chemical fertilizer. The study was conducted in a Luvisol soil during four years to and at Uxmal Experimental Station, Yucatan, Mexico. Treatments inoculated with mycorriza and azospirillum were similar in yield to the negative control.


Las bacterias y los hongos son capaces de proveer a la planta diferentes nutrientes en forma asimilable. El Brassinoesteroide es un producto natural, con una estructura esteroidal que estimula el desarrollo vegetal Gross y Parthier, ; Cluose y Sasse, El uso de microorganismos y de hormonas que estimulan el crecimiento de las plantas puede mejorar la eficiencia del uso de los fertilizantes fosfatados Cruz et al, ; Brown y Bethlenfalvay, ; Young et al, ; Werner, La parcela experimental fue de seis surcos de 5.
