SUMMARY:

 

Passion fruit is a crop of enormous importance for Brazilian fruit growing. The country presents itself as the world's largest fruit producer and also the largest consumer. In recent times, there has been an increase in studies on genetic materials under organic management in passion fruit crop, which also shows the need for work focused on monitoring fertilization with sources that meet the nutritional needs of the crop. According to Law 10,831 of 2003, which governs the mechanisms of organic production in the country, the restriction on the use of synthetic nitrogen fertilizers is highlighted, generating the need for strategies for the management of essential nutrients, especially nitrogen. Given this situation, it is essential to search for sources of organic fertilization in production systems, considering the input of N and the rate of decomposition in sync with the demand of crops. Studies related to the management of green manures and organic compounds in order to select those that provide a speed of decomposition of plant biomass and nutrient supply compatible with the periods of demand of crops of agricultural interest are important, favoring the success of farming practices. organic fertilization. This work aims to evaluate the availability of N from different plant sources in three biomass arrangements and the decomposition dynamics of gliricidia plant biomass in Passiflora edulis Sims cultivation. (sour passion fruit) in organic production system under the conditions of Baixada Fluminense. The experiment will be carried out in the Integrated Agroecological Production System (SIPA), located in Seropédica-RJ. The experimental design will be a randomized block design (DIC), with three replications, to evaluate the sources of N for fertilization in passion fruit cultivation, from different vegetable sources, and the decomposition rate of legume gliricidia. through the methodology of the litter bags.
