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.

O objetivo deste trabalho foi avaliar o efeito de cinco frequencias de irrigacao na produtividade e na eficiencia do uso da agua em meloeiro cultivado sob fertirrigacao por gotejamento em solo arenoso de Tabuleiro Costeiro do Piaui. O delineamento experimental foi em blocos ao acaso, com cinco tratamentos e seis repeticoes. Os tratamentos foram: F1, F2, F3, F4 e F5, correspondentes as frequencias de irrigacao de 0,5, 1, 2, 3, e 4 dias, respectivamente. A frequencia de irrigacao influenciou as produtividades comercial e total do meloeiro. As maiores produtividades totais (70,73 t ha-1, 77,99 t ha-1 e 64,21 t ha-1) e comerciais (67,20 t ha-1; 63,88 t ha-1 e 53,67 t ha-1) foram obtidas com as frequencias de 0,5 e de 1 dia, respectivamente. Com aplicacoes menos frequentes, houve reducao significativa (P<0,01) nas produtividades comercial e total do meloeiro. O peso medio dos frutos nao foi influenciado pelas frequencias de aplicacao de agua. A maior e a menor eficiencia de uso de agua, 24,40 kg m-3 e 14,14 kg m-3, foram obtidas com F1 e F5, respectivamente. As frequencias de irrigacao de duas vezes por dia, diaria e a cada dois dias, sao as recomendadas para o meloeiro cultivado em solo arenoso sob fertirrigacao por gotejamento. A eficiencia de uso da agua no meloeiro e maior quando as frequencias de irrigacao sao maiores. |
