Comparison of relative growth rates in silage corn cultivars

Abstract

This study was carried out, in Konya Bahri Dagdas International Agricultural Research Institute’s practice and research land. In the study, silage corn varieties growth analyses were made which depending on time. Relative Growth Rates (RGR) were measured all cultivar and times. While these analysis making 5 plants were taken from each plot and measured on these plants. Richards, Logistic, Weibull and Gompertz growth models were used for evaluating. At the models comparing determination coefficient (R2), mean square error were used. As a result this showed that RGR is different from growth features. Weibull function explained RGR better than other models for all of cultivars.
