- This study was conducted in the Lath Hause / Department of Horticulture and Landscape Design / College of Agriculture and Forestry / University of Mosul, during 2019 growing season , to study the effect of two factors and its interactions on the concentrations of some heavy metals in the leaves of Lokal orange (Citrus sinensis L.) transplants budded on soure orange (Citrus aurantium L.) cultivated on plastic pots filled with 8 kg of media (soil + sheep manuier 3:1),first factor was NPK fertilizer (20:20:20) which were added at two levels (0 and 30 gm.transplant-1) ,Meanwhile the second factor included five levels of biofertilizers (3 and 6 gm.Biogeain ,5 and 10 gm. Potasiomag and 1gm.Fulzyme.transplant-1) and Nutrigreen organic fertilizer at a concentration of 6ml.l-1 in respect to control . NPK fertilizer were added at two equal doses (15gm.transplant-1 in each dose), at 21/3 and 2/5/2020 respectively, biofertilizers were added at 21/3/2020 , Meanwhile the organic fertilizer were added at two times (26/3 and 3/5/ 2020) at the amounte of 200 ml. in each time. Resultes indicated that all biofertilizers and organic fertilizer significantly decresed leaves Co,As,Se,Ag and Cr concentrations, While the application of NPK significantly increased leaves As concentration only as compared with control.The best treatment was 30gm NPK +10gm Potasiomag .transplant-1 which gave the minimum concentrations of Co,Ag and Cr in the leaves , Meanwhile the minimum leaves As and Se concentrations was in the treatment of 0gm NPK + 10gm Potasiomag .transplant-1 .
