Great part of solid waste are deposited inappropriately near cities or in rural areas, contributing to negative environmental impacts. There are numerous forms of waste processing, one of them is pyrolysis to produce biochar and subsequent use in agricultural systems. The objective of this study was to evaluate different substrates with activated biochar (AB) and biochar (B) in substrate and its effect on the growth of passion fruit seedlings. The test was conducted in a nursery, located in Sinop/MT, May to July 2013, designed in four blocks with ten treatments: commercial substrate (CS), composed by pine bark and vermiculite 4:1; nursery substrate (NS) composed by carbonized rice husk and coconut fiber 1:1; and the eigth treatments represented were B and AB additions of 25; 50; 75; and 100% in CS, (B25, B50, B75, B100, AB25, AB50, AB75 and AB100, respectively). After 60 days sowing the stem diameter, plant height, leaf number was evaluated and at the end of the experiment the fresh and dry weight of shoots and roots, and Dickson Quality Index (DQI) were assessed. AB at concentrations of 25, 50 and 75% combined with commercial substrate showed increases in parameters fresh and dry biomass weight, height, stem diameter and number of leaves. The dose of 25% AB is presented as the best dose to be adopted in commercial crops. The sawdust processed into AB is an alternative in the production of passion fruit system and the reintegration of this raw material to the productive sector.

Purpose/objective: To describe the managerial challenges agricultural cooperatives face and list the leading solutions that can be adopted to overcome such bottlenecks. Design/methodology/approach: A systematic literature review was done, with a research protocol based on ?Methodi Ordinatio? (Pagani et al., 2015) to select relevant papers. The study covered aspects of management and administration of agro-industrial cooperatives, social management, risk management in agribusiness, strategic management in agribusiness, new generation cooperatives, cooperative management, cooperative governance and challenges to the cooperative system. Findings: Efficient conciliation of cooperatives? social and economic agenda requires management professionalization. The cooperative must adopt a series of good management and governance practices and a strategic positioning that guaranees a competitive position, putting it on an equal footing with private firms. The central management tools identified are separation between control and ownership, strategic management, strategic alliances and partnerships, management branding, restricted membership, social management, self-financing and risk management, with numerous other management options available. The main obstacles are the conservative environment and the need to update cooperative doctrinal principles, impediments to modernizing Brazilian agricultural cooperatives? management. Originality/value: The paper identifies aspects of a conservative environment and the need to update the cooperative principles that hinder the modernization of the management in Brazilian agricultural cooperatives.
