MYCORRHIZAL ACTIVITY AS A QUALITY INDICATOR IN FOREST LIVESTOCK CROP INTEGRATION SYSTEM WITH CAGAITA - EUGENIA DYSENTERICA

Abstract

THE SYSTEM OF CROP, PEQUACIA AND FLORESTA INTEGRATION IS DEFINED AS A SUSTAINABLE PRODUCTION STRATEGY, WHICH INTEGRATES AGRICULTURAL, LIVESTOCK AND FORESTRY ACTIVITIES, CARRIED OUT IN THE SAME AREA, WHETHER IN A CONCROP, SUCCESSION OR ROTATION. THUS, IT COVERS DIVERSIFIED PRODUCTION SYSTEMS FOR THE PRODUCTION OF FOOD, FIBERS, ENERGY, TIMBER AND NON-TIMBER PRODUCTS, AS WELL AS PRODUCTS OF PLANT OR ANIMAL ORIGIN, IN ORDER TO OPTIMIZE THE BIOLOGICAL CYCLES OF PLANTS AND ANIMALS, AS WELL AS THE INSUMS AND THEIR RESPECTIVE RESIDUES. 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 MYCORRHIZAL COLONIZATION AS AN INDICATOR OF ENVIRONMENTAL QUALITY IN A SYSTEM OF CROP, LIVESTOCK AND FOREST INTEGRATION USING CAGAITA. THE TREATMENTS EVALUATED WERE 1) CAGAITA + ARACHIS PINTOI./CALLOPOGONIUM MUCUNOIDES; 2)  CAGAITA + CROTALARIA JUNCEA L;3)  CAGAITA + DOLICHOS LABLAB L;4)  CAGAITA + UROCHLOA DECUMBENS WITHOUT NITROGEN  AND; 5)  CAGAITA + UROCHLOA DECUMBENS WITH NITROGENIO. TREATMENT 3 SHOWED HIGHER SPORE DENSITY THAN THE OTHER. THERE WAS NO DIFFERENCE IN MYCORRHIZAL COLONIZATION RATE IN THE TREATMENTS EVALUATED.
