A fieid experiment to establish the influence different fertilizers for foliar spray on the growth of pepper, was carried out in 2007-2008 at the area of Kavarna. Several variants have been tested: 1. N0P0K0; 2. N12P6K6; 3. N24P12K12; 4. Grogreen (N20P20K20 + ME); 5. Hortigrow universal (N20P20K20); 6. Kristalon special (N18P18K18Mg3); 7. N12P6K6 + Grogreen; 8. N12P6K6 + Hortigrow universal; 9. N12P6K6 + Kristalon special; 10. N24P12K12 + Grogreen; 11. N24P12K12 + Hortigrow universal; 12. N24P12K12 + Kristalon special. As a result it was found that foliar spray could to a great extend compensate the reduced content of mineral fertilizers in the soil.
