Sažetak
As the most important quality parameters of the hops the development of mathematical models for predicting of alpha-acids accumulation in hop cones is very important for planning of hop stocks in order to avoid the market stress. The aim of this study is to verify the accuracy of the empiric mathematical model for predicting the content of alpha-acids in hop cones of cv. Aurora using the linear regression, general linear regression and Cobb-Douglas production model-function. The values of standard deviations (σ) of differences between predicted and analyzed content of alpha-acids for used methods are much lower in the comparison with the empiric mathematical model of alpha-acids prediction in the case of non-compliance with the strictly set condition for reliability of the empirical mathematical model, according to which the daily reference crop evapotranspiration (ET0) in July  4.5.
