A method for an agroeconomic analysis of fertilizer experiments with mixed crops

, : A method for an agroeconomic analysis of fertilizer experiments with mixed crops. Pesquisa Agropecuaria Pernambucana 3(2): 161-182

Data for response to fertilizers were taken from a mixed crop of maize and beans and used to demonstrate a method for analysis of performance of fertilizers with mixed crops. Six levels of phosphate application, plus a control, were used in a random block experimental design. Quadratic functions were used in regression analysis and compared with the Mitscherlisch equation and the square root function.
