Physio-chemical studies of some irrigation water sources from Ogbia, Bayelsa state and their effects on elemental composition of Zea mays L.
Journal Title: INTERNATIONAL JOURNAL OF RECENT TRENDS IN SCIENCE AND TECHNOLOGY - Year 2017, Vol 22, Issue 1
Abstract
The physico-chemical characteristics of four different water sources and their effects on the elemental composition of Zea mays L. were evaluated in the laboratory for two (2) weeks. Standard procedures were used to determine the physico-chemical characteristics (pH, salinity, conductivity, turbidity, TDS, TSS, COD, BOD, DO, Mg, Ca, Na, K, Pb etc) of the water samples. Seedlings of the test crop were raised and irrigated with varied sources of water samples alongside a control treatment (distilled water). Mineral nutrient composition of the plant (Pb, Cd, Cr, Ca, Mg, Na, K, NO3-, PO4, Fe, Cu, Zn, and Mn), were estimated. The results showed that there were marked differences (P < 0.05) in the physico-chemical characteristics of the four water samples. The highest content of potassium, sodium and phosphate were recorded in decreasing order from stream, tap, rain and distilled water, while, the Mg, and Mn contents in the test crop were in the decreasing order from stream, rain, tap and distilled water. In addition, there were significant differences (P < 0.05) in the content of Ca among the four water sources, with values higher than that of the control. This study suggests that there is need for appropriate environmental pollution control measures, in order to keep some water parameters within optimum range for proper metabolism in the test crop in the study area.
