Berhe Akele* and Shisho Haile
The study was conducted in Yeki woreda Southern Nations Nationalities and Peoples Regional State, Ethiopia. Systematic random sampling Technik was followed throughout the study. Fruit and soil samples were collected from 8 kebeles of the study area. A total of 50 fruit samples per each fruit item were randomly selected from each site. Fruit samples were desiccated at 90°C for 48 hours in oven and the dried samples were ground. 0.25 kg of soil samples were collected from the soil at which the fruit plant grows. The samples were collected from all directions within 20 cm depth and were dried in oven at 90°C for 24 hours. 0.5 g of fruit sample was digested by the mixture of HCl, HNO3 and H2O2 (3:1:2) at 90°C for 2 hr and 0.5 g of soil sample was digested with the mixture of HNO3 and HClO4 (3:1) at 90°C for 2 hr. pH and EC values of soil and fruit samples were measured by pH meter and an EC meter. OM and moisture content of samples were also determined. The moisture content ranges from 38.5–57.74 for fruit and 66-71.33 for soil samples. OM of the samples was ranges from 7.77– 19.39 for fruit samples and 79.72–85.00 for soil samples. Electrical conductivities of the samples were ranges from 0.06–0.09 mS/cm for fruit samples while that of soil samples was 0.33-0.54 mS/cm. pH values obtained ranges from 7.24-7.56 for fruit samples while it was 7.35-7.66 for soil samples. The concentration of Ca>Cu>Zn>Pb in all samples. Cr was not detected in all fruit samples but detected in all soil samples. Ni and Cd were not detected in all the samples. The means of the metals were significantly different for both samples separately (p<0.05). Transfer factor of the metals is almost higher at mango followed by banana and avocado respectively.
