Growth, Productivity and Biomass Quality of Kenaf Irrigated with Wastewaters - the Effect of Nitrate Ion

A.L. Fernando, M. Ferreira, S. Boléo, B. Mendes & E. Alexopoulou
The aim of this work was to evaluate growth responses, as well as the quality and biomass productivity of the G4 variety of kenaf, irrigated with treated wastewaters (TWW) presenting different nitrate ion concentrations: 0, 50 e 100 mg.L-1 (NO3). Wastewater was obtained at Campo de Tiro de Alcochete wastewater treatment plant, after secondary treatment. Essays were conducted in small pots, and for each treatment, in triplicate. NPK fertilization effect was also studied. A Control...
