SOTELO D, LUZ INDIRA; JIMENEZ F., JAVIER ALEXANDER; DE ZAN, ARTURO TARSICIO  e  CUETO V, MARIA CLEMENTINA. EFFECT OF INOCULATION OF MICROORGANISMS ON RADISH GROWTH (Raphanus sativus). Rev.Bio.Agro [online]. 2012, vol.10, n.1, pp.21-31. ISSN 1692-3561.

The effect of microorganism's inoculation that could stimulate the growth in plants has been of great interest for bioinsumos production in last years. Strain of Azotobacter sp, Bacillus pumilus and Bacillus licheniformis were isolated and identified of GEO ® composting process and inoculated in a radish culture (Raphanus sativus). Experimental design was realized with five treatments and a control, with 15 repetitions; each microorganism strain was to put individually in growth culture. The treatments took place twice by aspersion with interval of 15 days during radish culture. The response variables evaluated in radish culture were: length of plants, number of leaves and dry weight of root radish. With treatment T5 (mix of three microorganisms), the results showed a minor effectiveness in root biomass production; in addition was a greater yield in all characteristics with the use of chemical fertilization. Nevertheless, the individually applied of each microorganism present promissory results for the application in agriculture cultures of short cycle.
