Development of the primary values of yield tables of spruce in comparison with their development on permanent research plots

Development of yield curves of mean and top height and development of mean diameter of the yield tables of spruce is compared with their development on 28 permanent research plots with 156 repeated measurements. The time gap of repeated measurements on research plots is in the range of 10-38 years....

Description
Summary:Development of yield curves of mean and top height and development of mean diameter of the yield tables of spruce is compared with their development on 28 permanent research plots with 156 repeated measurements. The time gap of repeated measurements on research plots is in the range of 10-38 years. The agreement and differences in the development of model and empirical curves were examined by means of mathematical and statistical characteristics. The development of mean and top heights in the yield tables of spruce is consistent with their development on permanent research plots. Mean diameters of yield tables are systematically smaller by about 4%.
