Sažetak
Influence of soil compaction and fertilization on the growth and development of flue-cured tobacco was investigated at the experimental station of the Tobacco Institute Zagreb at Pitomača. Research was carried out in model trials, in Mitscherlich's pots. Three soil compaction levels (1.2, 1.4 and 1.6) and three fertilization rates (N0P0K0, N1P1K1 and N2P2K2) were randomized according to the split-plot method with four replications. The soil used in the trials was the plough layer of Luvisol, the soil typical of the area in which flue-cured tobacco is grown in Croatia. Tobacco was picked in six harvests, and after the sixth harvest the tobacco root yield was determined by washing it out in a sieve. The soil resistance to penetration was measured during tobacco flowering, and a statistically significant increase of soil resistance (compaction) was recorded in the soil with medium and the highest bulk density compared to that with the lowest density. Increased soil compaction considerably reduced leaf yields and root development of tobacco. Tobacco leaf and root yields were significantly increased by intensified fertilization. The highest leaf and root yields were obtained in the combination of the lowest soil compaction and the highest fertilizer rate. Increased application of NPK fertilization did not compensate for increased soil compaction.
