| Abstract: | According to the purpose of minimizing experimental cost and the requirement of experimental precision, objective and restriction functions were constructed and nonlinear program model was proposed for optimizing the number of years and locations and replications in regional crop trial. Methods and problems about each parameter's estimation and determination in this model were expounded in detail. The experimental design of Yellow River regional cotton trial was analyzed as an example. A new precision index of regional crop trial was developed and discussed as well. |
