Abstract
Based on an investigation carried out in the years from 2001 to 2003 with the plum cultivar ‘Čačanská Lepotica’ planted in moderately heavy alluvial soil, of weak acid reaction (pH-5.9), poor in humus (2.65%), moderately supplied with N (0.13%), moderately supplied with K2¬O (20.4 mg/100 g) and well supplied with P2O5 (15 mg/100 g), it was found that the application of different rates of NPK fertilizers of formula 8:16:24 +3% Mg, positively affected the cropping potential.
The highest yield were obtained when 400 kg/ha of fertilizer was used (6.28 kg/tree, i.e. 18,683 kg/ha). Unfertilized plots had the lowest yield (4.61 kg/tree, 13,677 kg/ha).
The medium planting distance (4 x 0.85 m) had the highest yield.
The fruit size increased with increasing amount of fertilizing, and with lower planting density.
