Abstract. The effect of macro- and microelements used in fertigation on growth and yield of highbush blueberry cv. ‘Bluecrop’ was searched. There were tested 3 levels of nutrient solutions used in drip fertigation F-1, F-2 and F-3. The best yield was found in application nutrient solution F-1 contains (in mg·dm-3): 10 N-NH4, 90 N-NO3, 30 P-PO4, 60 K, 85 Ca, 30 Mg, 48 S-SO4, 0.192 Fe, 0.300 B, 0.030 Mo and F-2: 25 N-NH4, 125 N-NO3, 45 P-PO4, 90 K, 85 Ca, 45 Mg, 48 S-SO4, 0.192 Fe, 0.300 B, 0.03 Mo. Nutrient solutions F-1 and F-2 had positive effect on growth, yield, weight of 100 fruits and height of bushes.

Summary
Study was done in the years 2002-2003 with highbush blueberry cv. ‘Bluecrop’. The effect of macro and microelements used in fertigation on growth and yield was searched. There were tested 3 levels of nutrient solutions used in drip fertigation F-1, F-2 and F-3. It was found the positive effect of fertigation with application of nutrient solutions F-1 contains (in mg·dm-3): 10 N-NH4, 90 N-NO3, 30 P-PO4, 60 K, 85 Ca, 30 Mg, 48 S-SO4, 0.192 Fe, 0.300 B, 0.030 Mo and F-2: 25 N-NH4, 125 N-NO3, 45 P-PO4, 90 K, 85 Ca, 45 Mg, 48 S-SO4, 0.192 Fe, 0.300 B, 0.03 Mo on growth, yield, weight of 100 fruits and height of bushes. Fertigation with the nutrient solution on the level F-3 reduced the yield of fruits without symptoms of disorders in plant nutrition.
