Campomanesia adamantium (Cambess.) O. Berg (guavira) is a native plant of the Cerrado and Pantanal, which has several medicinal activities and fruits with a unique flavor rich in vitamin C. The species does not have defined cultivation methods, requiring studies to increase biomass production. An alternative is the use of organic residues that can influence the chemical, physical and biological characteristics of soils and consequently increase plant production. Thus, the objective was to evaluate the effect of different organic residues and bokashi, on the biomass production of plants and on the levels of phenols, flavonoids and antioxidant activity of tea from the leaves of guavira. Five substrates were studied in pots and protected environment: soil; soil + rice husk chicken manure; soil + sawdust chicken manure; soil + castor bean cake; soil + Organosuper® with or without the use of Bokashi in a 5x2 factorial scheme, in a randomized block experimental design. It was observed that the rice husk chicken manure can be used to increase the initial growth and biomass production of guavira keeping the leaves antioxidant activity tea stable. The use of bokashi benefits the growth of guavira only when no other organic residue is added to soil. [ABSTRACT FROM AUTHOR] |
