Bioaccumulation of heavy metals in tomatoes (Lycopersicum esculentum) grown in soil amended with different biofertilizers in Sargodha, Punjab Pakistan

摘要

Effects of different biofertilizer on growth of Lycopersicum esculentum was perform in a pot experiment. Sugarcane press mud, poultry waste and farmyard manure was used in the farming of Lycopersicum esculentum as a bio fertilizer. Four pots were selected to check the effects of bio fertilizer such as press mud (T1), poultry waste (T2) and farmyard manure (T3), fourth one was control condition (T0). T1 contain 50% sugarcane press mud and 50% garden soil), T2 contain 50% poultry waste and 50% garden soil) and T3 contain 50% farmyard manure. Heavy metals concentration in L. esculentum samples for cadmium, cobalt, chromium, copper, lead, ferric, manganese and zinc were assorted from 0.354 to 0.379, 2.0091 to 3.96, 0.685 to 1.202, 2.188 to 6.778, 0.0529 to 0.17, 1.368 to 5.031, 0.025 to 0.157 and 2.717 to 5.173 mg/kg, respectively. BCF estimations of metals in vegetables and soil were seen in safe limit. Cu demonstrated the BCF most extreme level (6.82) and Cd demonstrated the lower esteem (0.087). DIM value assessed for L. esculentum samples was found inside safe limit. The most elevated HRI was found for Cd at T3 and the least for Cr at T2 treatment. PLI esteem was discovered the most elevated for Cd (2.90) and the least for Pb (0.0028).
