Growth of Four Varieties of <i>Coffea arabica</i> L. Biofertilized with <i>Rhizophagus intraradices</i> and <i>Azospirillum brasilense</i> in Nursery

Coffee production has decreased due to environmental and management factors. The current plantations are old unproductive, also the rust problem, caused by fungus Hemileia vastatrix Berk & Br. Furthermore, shade in systems with consequent increase soil erosion, addition agrochemicals. Currently, planting of new varieties resistance is increasing. it been shown that various biofertilized perennial crops nursery favor their growth. In this study, effect applying two beneficial microorganisms, Rhizophagus intraradices and/or Azospirillum brasilense, four Coffea arabica L. was evaluated. coffee marseillase, geisha, sarchimor costa rica 95 were established bags following treatments: 1) control, 2) R. intraradices, 3) A. 4) + brasilense. Morphological physiological yield components recorded 168 days after transplanting. Data analyzed statistically differences between treatments compared according Tukey (p ≤ 0.05). results indicate individual or combined biofertilization microorganisms favors dry matter allocation control same differentially assigned stem root. Specific Leaf Area (SLA) showed differential response applications increased when they applied alone others together.
