Sewage sludge is a household waste, industrial or agro- containing organic matter, macro and micronutrients. This residue can be used in agricultural systems after health treatment as a form of organic manure, being used for purposes of correcting and fertilize the soil, improving the physical, chemical and even biological. To this end, the objective is to work, analyzing the influences and interactions between applications of composted sewage sludge and phosphorus levels, as well as the combined effect of liming and silicatagem, growth and yield of castor bean -sized bass. Work will be performed in pots under plastic tunnel, Lageado at the Experimental Farm, near the Faculty of Agricultural Sciences - FCA, Botucatu campus. The treatments are four combinations of soluble source of phosphate fertilizer with sewage sludge composted and four combinations of lime silicate melt shop, featuring a 4 x 4 factorial design with four replications in a randomized block design. In soil chemical characteristics will be evaluated for fertility at the time of flowering castor bean plants. And the plant will be evaluated: plant height, stem diameter, leaf area, number of bunches per plant, number of fruits per bunch, percentage of seeds per fruit, fruit yield, oil content in grain and nutrient content the grain. The data will be analyzed statistically.
