Evaluation and Responses of ZEA Mays Seedlings to Soil Micronutrients Toxicity
Journal Title: IOSR Journal of Agriculture and Veterinary Science (IOSR-JAVS) - Year 2018, Vol 11, Issue 12
Abstract
Green-house experiment was conducted on zea mays planted on sandy soil to determine the toxic levels of Zn2+, Mn2+, Cu2+ and Fe2+ in the leaf of seedling of the plant. This was achieved by applying 250cm3 of 10PPM, 50PPM, 100PPM, 150PPM, 200PPM and 500PPM of Zn2+, Mn2+, Cu2+ and Fe2+ at intervals until toxic level was indicated through change in colour of the leaves. Diethylene triaminepentaacetic acid (DTPA) was used to extract the micronutrients in the soil and the concentrations were evaluated using, Atomic Absorption Spectrophotometer (AAS). The concentrations of the micronutrients in leaves were also determined using AAS. The concentration of the micronutrients in leaves of the plant in the soil at toxic levels were 250PPM- 260PPM Zn2+, 37.24PPM-55.90PPM of Cu2+ , 290-320 of Mn2+420-700 of Fe2+. The results were statistically treated using t-test to determine the significant difference in the uptake of the micronutrients byZea mays in sandy soil.
