MYCORRHIZAL ACTIVITY AS A QUALITY INDICATOR IN FOREST LIVESTOCK CROP INTEGRATION SYSTEM WITH BARU - DIPTERYX ALATA

Resumo

THE CONCEPTS OF CROP-LIVESTOCK-FOREST INTEGRATION SYSTEMS (ILPF) ARE QUITE BROAD AND ENCOMPASS SEVERAL INTEGRATION MODALITIES THAT CAN CONTEMPLATE AGRICULTURAL, LIVESTOCK AND FORESTRY ACTIVITIES, IN THE SAME AREA, IN SUCCESSION, IN ROTATION AND/OR SIMULTANEOUSLY, TAKING ADVANTAGE OF SYNERGIES BETWEEN THEM. MORE RECENTLY, THE ILPF CONCEPT ENCOMPASSED THE AGRICULTURE-LIVESTOCK INTEGRATION (IAP) OR CROP-LIVESTOCK INTEGRATION (ILP) AND THE AGROFORESTRY SYSTEM (SAF), WHICH HAVE BEEN PRACTICED FOR LONGER IN BRAZIL. THE DETERMINATION OF A QUALITY ASSESSMENT METHODOLOGY IS FUNDAMENTAL AS A MANAGEMENT AND DECISION-MAKING TOOL. IN THIS SENSE, THE OBJECTIVE OF THIS STUDY WAS TO EVALUATE THE DENSITY OF SPORES AND  THE RATE OF MYCORRHIZAL COLONIZATION AS AN INDICATOR OF ENVIRONMENTAL QUALITY IN A SYSTEM OF CROP, LIVESTOCK AND FOREST INTEGRATION USING BARU. TREATMENTS WERE EVALUATED: 1) BARU + ARACHIS PINTOI./CALLOPOGONIUM MUCUNOIDES; 2) BARU + CROTALARIA JUNCEA L; 3) BARU + DOLICHOS LABLAB L; 4) BARU + UROCHLOA DECUMBENS WITHOUT NITROGEN AND 5)BARU + UROCHLOA DECUMBENS WITH NITROGENIO. TREATMENTS 1 AND 5 SHOWED HIGHER SPORE DENSITY VALUES. THERE WAS NO SIGNIFICANT DIFFERENCE IN MYCORRHIZAL COLONIZATION BETWEEN TREATMENTS.
