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.

Cinco pares de populacoes de milho braquitico 'Piranao' (A0, A1, A2, A3 e A4) e 'Cimmyt' (B0, B1, B2, B3 e B4), seus 25 hibridos correspondentes e uma testemunha, obtidos pelo programa de selecao recorrente reciproca entre familias de irmaos completos (SRRFIC) da UFV, foram avaliados em latice simples 6 x 6, com duas repeticoes, em dois locais, O objetivo do trabalho foi verificar a eficiencia da SRRFIC, por meio de uma metodologia baseada em alguns parametros geneticos, em produzir populacoes e hibridos superiores, quanto ao incremento das frequencias dos alelos favoraveis e da heterose com o avanco das geracoes de selecao. As maiores partes de ganhos geneticos, nas populacoes, foram devidas aos efeitos aditivos na troca dos alelos desfavoraveis pelos favoraveis do que pelos efeitos de dominancia. Para os hibridos, os dois fatores foram importantes. Com base nas medias ajustadas, observou-se que os hibridos superaram as duas populacoes nos dois locais. Comprovou-se a eficiencia da SRRFIC em promover ganhos, como tambem foram satisfatorios os ganhos geneticos estimados pela metodologia aplicada. |
