A study of statistical growth models and growth database.

Plant Physiologists and crop modelers in general are keen to use non-linear models for their work. However, usual practice remains restricted to the use of linear form of growth curves due to lack of proper methodology for the application of non-linear models. This study is undertaken to review the statistical literature available on non-linear models, comparison of these models with data sets available. A database management system known as GROWDAT for growth data has been developed for a systematic storage and retrieval of growth data collected from several experiments. A copy of the software will be given on request.
