Determining the Number of Seeds to Sow per Cell: An Application of the Geometric Distribution

Using germination data, specifically total germination percentage, to determine sowing rates is necessary for effective resource allocation in container nurseries. Traditionally, binomial probability tables and, more recently, microcomputer programs are employed to determine sowing rates in container nurseries. Existing computer programs may require several iterations to deduce sowing rates, depending on test gemination percentage. When used with the binomial probability function, the geometric probability function alleviates the need to run multiple iterations of a program. We provide programming language for a spreadsheet program that combines these two probability functions to determine sowing rates. Tree Planters' Notes 48(1/2): 28-34; 1997.
