dc.description.abstractA two-factorial laboratory experiment was carried out at the Alexandras Stulginskis University (ASU) of the Experimental Station in 2013. The soil of the trial site was an Calc(ar)i-Endohypogleyic Luvisol (LVg–n–w–cc), clay loam. Experiment treatments: Factor A – potato tuber germination: 1) non-germinated potato tubers, 2) germinated potato tubers. Factor B - soil bulk density: 1) 1.0 Mg m-3, 2) 1.2 Mg m-3, 3) 1.4 Mg m-3, 4) 1.6 Mg m-3. Investigations were carried out in six replicates. Investigation results show that an increase in soil bulk density, compared with the lowest bulk density and non-germinated and germinated potato tubers substantially increased crude fiber content (r = 0.98, P < 0.05 and r = 0.99, P <0.01), and protein content substantially decreased (r = –0.97 and r = –0.98, P < 0.05). An increase in soil bulk density, compared with the lowest bulk density, non-germinated potato tubers, green ash substantially increased (r = 0.96, P < 0.05), while the germinated potato tubers essentially unchanged. Between soil bulk density and dry matter content of not sprouted tubers in a linear, very strong and statistically significant correlation (r = 0.98, P < 0.05) between soil bulk density and dry matter content of sprouted tubers – power – law and statistically significant correlation (r = 0.94, P < 0.05). Germinated potato tubers, compared to non-germinated, substantially increasing crude fiber and ash content, and dry matter and crude protein content decreased substantiallyen
