QUALITY OF POTATO FROM CULTIVATION WITH LEISA SYSTEM CULTIVATION

The purpose of this study is to examine the effectiveness of bioremediation process of insecticide and fungicide residues. Research on consumption of potato cultivation using spread seeds or seedlings. The study looked at the metal content parameters in the soil and in potato tubers. The metal content of Fe, Pb, Cd and Cr in the soil especially in the root zone of potato cultivation of granola varieties at the beginning of potato cultivation varied from 204.0 to 2013.5 ppm, 14.4 - 70.9 ppm, 0.78 - 5.41 ppm and 1.37 - 7.07 ppm, and the end of cultivation are 157.0 - 1156.6 ppm, 8.8 - 52.8 ppm, 0.44 - 2.76 ppm, and 0.37 - 3.61 ppm. Velocity of bioremediation of is Fe = 25.56 ± 3.6 ppm/month, is Pb = 0.19 ± 0, 03 ppm/month, is Cd = 0.23 ± 0.08 ppm/month, and is Cr = 0.73 ± 0.04 ppm/month. At dosage compost fertilizer is 20 tons/ha, the metal concentration of Fe = 6.14 ± 0.02 - 7.37 ± 0.09 ppm, Cd = 0.1 ± 0.004 - 0.13 ± 0.007 ppm and Cr = 0.11 ± 0.04 - 0.14 ± 0.002 ppm.
