Avaliação do desenvolvimento de mudas de sapucaia (Lecythis pisonis Cambess) inoculadas com fungos micorrízicos e vermicomposto em área de reserva legal

Abstract

The Amazon is considered one of the major biomes on biological diversity is the flora or fauna. Seen as the last part of the agricultural frontier in Brazil, in the late twentieth century the region was the subject of intense exploration activities in various resources. The first experiments were with reforestation using exotic species said, this was due to the lack of incentives in the management and production of native species among producers. Resort to native species as a resource for people natural areas is a required strategy to compliance with the environmental laws. This work was carried out on the Crystalline farm in São Domingos do Araguaia-PA. The objective of this study was to evaluate the development of sapucaia (Lecythis pisonis Cambess) inoculated with mycorrhizal fungi and vermicompost to make legal reserve areas in southeastern Pará. The experimental design consisted of one block containing split plot, with 3 treatments, 4 replicates and one plant species (3 x 4 x 1 = 12 plots) with 16 plants in each plot, where only 4 plants were evaluated. Treatments were control (T1), vermicompost (T2) and arbuscular mycorrhizal fungi (AMF) + vermicompost (T3). We evaluated the plant height and number of leaves and stem diameter. Data were subjected to analysis of variance using the SAS 9.1 software. 180 days were evaluated the above morphological parameters. The sapucaia seedlings treatment with vermicompost showed better response to the parameters assessed for the plants nutrient availability speed. The sapucaia seedlings responded better to treatment with vermicompost (T2), followed by control (T1) and finally to treatment with FMAS + Vermicompost (T3). Seedlings of sapucaia had a good development in the field, showing that the seedlings with vermicompost production technology becomes a viable alternative to compose legal reserve areas.
