DISTRIBUTION OF INOCULUM AMF AGROFORESTRY SYSTEMS FOR THE FAMILY FARM

Abstract

ABSTRACT: Most upland soil of the Amazon has high acidity and nutrient deficiency, which prevents the satisfactory growth and development of plants. As an alternative to producing high quality seedlings for the region, has given prominence to the use of arbuscular mycorrhizal fungi (AMF), which promote better development of plants in adverse environmental conditions. Therefore, the objective was to produce and distribute MF inoculants for farmers interested in deploying it in their cropping systems in settlement projects in the region. The study was conducted at the Faculty of Agrarian Sciences of Maraba, in the Federal University of Pará and settlement projects in the region, where soil samples were collected in several areas of cultivation for the extraction of spores, which were multiplied in trap culture Brachiaria brizantha, in order to produce inoculum for distribution to farmers interested in technology. The occurrence of arbuscular mycorrhizal fungi in different cropping systems of the settlements involved were verified and identified farming families interested in using the inoculant. The multiplication of spores to produce inoculum was satisfactory, since it was produced in sufficient quantity to meet the demand of 25 families involved, which were distributed to 1830 doses of inoculation, demonstrating the great interest of farmers in improving their systems production.   KEY-WORDS: mycorrhiza, technological innovation, production system.
