Growth and accumulation of macronutrients in maize plants biofertilized with cassava wastewater

The aim of this study was to evaluate the growth and nutrient accumulation in maize plants fertilized with cassava wastewater. The experiment was carried out under greenhouse from March to May 2011. The experimental design was completely randomized, in a factorial 2 (soil types: sandy loam and clay loam) x 4 (doses of cassava wastewater: 0; 11.2; 22.4 and 44.8 m(3) ha(-1)) arrangement, with eight replications. The variables analysed consisted of: plant height, stem diameter, number of leaves, fresh and dry mass of shoot and N, P, K, Ca and Mg content in leaf tissue. The use of cassava wastewater contributed to reduce plant height and increase both fresh mass of shoots and potassium content in leaf tissue. Increase in shoot fresh was higher in sandy loam soil.
