In 2004 пїЅ 2006 at the experimental field of the department of Horticulture at the Agricultural University пїЅ Plovdiv at Molic Fluvisols soil, a trial was carried out to evaluate the efficacy of foliar spray on eggplant cv. Patladjan 12, grown as mid-early field production. The variants tested were: 1 N0P0K0 пїЅ control; 2 N12P6K6 пїЅ backgroud; 3 N24P12K12 пїЅ background; 4 Fitona 1; 5 Hortigrow; 6 Agroleaf; 7 Kristalon; 8 N12P6K6 + Fitona; 9 N12P6K6 + Hortigrow; 10 N12P6K6 + Agroleaf; 11 N12P6K6 + Kristalon; 12 N24P12K12 + Fitona.; 13 N24P12K12 + Hortigrow; 14 N24P12K12 + Agroleaf; 15 N24P12K12 + Kristalon per da. More intensive assimilation of Zn was established in variant fertilized with N12P6K6 + Fitona. It was established relationship between the zinc content in leaves and the level of productivity, the concentration of photosynthetic pigments, the functional activity of photosynthesis apparatus of eggplant.
