Abstract: Randomized Complete Block Design (RCBD) field experiment was carried out at the Teaching and Research farm of Federal University of Technology, Akure, Southwestern Nigeria. The Research is aimed at monitoring soil water dynamics and evaluating the impact of soil properties such as soil pH, soil electrical conductivity and soil salinity on the growth and yield of Cucumber (Cucumis sativus) using 2D-Electrical Resistivity Tomography (ERT) method. Results from various surveys conducted were subjected to statistical correlation in order to determine existing statistical relationships between measured soil properties as they influence the growth and yield of the crop, as well as analyzing electrical resistivity responses...........

Abstract: The geochemistry and mineralogy of the Sakpe Ironstone were studied around Jima, Northern Bida Basin, Nigeria. Ten representative samples of the ironstone submitted for geochemical and mineralogical studies using X-ray fluorescence spectrometry, transmitted light microscopy and X-ray diffraction techniques. The result of the chemical analysis revealed that the ironstone contain an average of 58.9wt% Fe, 28.94wt% Si and 12.91 % Al. The average concentrations of P, K, Ca, Ti, Mn, Mg, and Na are 0.03wt%, 0.002wt%, 0.071wt%, 0.177wt%, 0.184wt%, 0.027wt% and 0.008wt%respectively. The results show that the ironstones are of high grade, having iron content > 54 % set by the Natural Resources Canada. Similarly, the low Mg (MgO wt %) content of between 0.01 and 0.051and absence of sulphur in the ironstonesshows that the sediments............

Abstract: The main purposes for constructing dams are to supply water (for drinking and irrigation) and to generate hydroelectricity. But severe environmental and socio-economic effects have been realized during and after construction of dams and reservoirs. The water from the reservoirs submerges many agricultural land and habitats that dramatically change in land use pattern of the surrounding areas besides ecodegradation. Some major projects such as the Loktak hydroelectric project have impacted badly the wetland ecosystem of the Loktak Lake and surrounding areas. It threatens the habitats of many flora and fauna including endangered Sangai (Cervus eldi eldi) and the livelihood of surrounding people. Hence, in this paper, we attempt to find out the positive and negative effects induced by the dams constructed at different parts of Manipur to the environment and socio-economic life of the people.
