Efeito de doses do composto orgânico Bokashi na qualidade do solo infectado com Fusarium sp e cultivado com melancia.

Abstract

Many diseases affect watermelon highlighting the roots of rota. The use of organic waste such as Bokashi is an alternative for the reduction of pathogens and improve the quality of the soil, making it suppressive. This study aimed to evaluate the effect of organic compost Bokashi in biological attributes and biochemical indicators of soil quality infected with Fusarium sp cultivated with watermelon. The work was conducted in a greenhouse in the CCTA / UFCG campus of Pombal where weekly doses of organic compost were evaluated Bokashi(14ml, 28ml. 56ml and 1 12ml / plant) in the ground, using cv. Watermelon Crimson Sweet. To meet this purpose, soil samples were collected in each subplot at different times (0, 30, and 60 days after planting watermelon) which were evaluated microbiological activity (soil respiration), microbial biomass carbon and metabolic quotient (qCO2). The experimental design was a randomized block consisting of six treatments (doses of Bokashi and positive and negative controls) with ave repetitions. There was a significant correlation between treatments and ranges collection where the biological and biochemical attributes evaluated presented different behaviors. Keywords:
