ABSTRACTThe study on bioaccumulation of lead and cadmium from contaminated soil into Amaranthus hybridus grown in irrigation farm lands in zaria, Kaduna state, Nigeria was carried out to assess the risk to human health by heavy metals (Pb and Cd) through the intake of grown vegetables (Amaranthus hybridus) from bomo lake, river galma and borehole water irrigated site. The samples collected (A. hybridus and soil) were separately digested and the heavy metals were analyzed using Atomic absorpti...
ABSTRACT: Residual levels of lead, chromium, cadmium and zinc in water and fish tissue from Ubeji River, Warri and blood samples from residents of Ubeji were analysed. Control water and fish samples were obtained from Eleyele River and blood from residents of Ibadan. All the samples collected were digested using a modified procedure from the Association of Official Analytical Chemists (AOAC) and were subsequently analyzed using Atomic Absorption Spectroscopy. Levels of lead and cadmium in Ube...
Abstract Across West and Central Africa, duikers are important for trade and consumption; their populations are expected to become depleted. Reliable data on their status are scanty in Nigeria. We assessed duiker populations in the Oban Sector of Cross River National Park through diurnal and nocturnal surveys along 32 transects of 2 km each. After 508-km survey effort, only Ogilby’s duiker (Cephalophus ogilbyi) and blue duiker (Philantomba monticola) were recorded. Using habitat as a covari...
Abstract: A two-year field experiment was conducted to evaluate the influence of nitrogen (0, 30, 60, and 120 kg N ha-1) and phosphorus (0, 30, and 60 kg P2O5 ha-1) application on grain yield and yield components of five New Rice for Africa (NERICA) cultivars, their parents, and a check on a degraded soil in the moist savanna of Nigeria. Nerica 14 recorded the highest grain yield of 1.3 mg ha-1compared to the other NERICA cultivars. It also produced significantly (P < 0.05) longer panicles (1...
ABSTRACT Microscopic examination of pollen grains determined the botanical origin and geographical location of honey. This study was aimed at determining the botanical sources of honey using qualitative and quantitative pollen analysis. Ten grams (10g) of honey was diluted with 8ml of distilled water and centrifuged at 2,500 rpm for ten minutes, and the sediments were used to analyse the po...
Abstract Low fruit quality and yield in cucumber is linked directly to continuous cropping under poor soil fertility management practices in Nigeria. In 2014 and 2015 planting seasons, field trials were conducted at the National Horticultural Research Institute (NIHORT), Ibadan to determine effects of poultry manure and NPK 15:15:15 fertilizer on growth, nutrient uptake and yield of cucumber on Ferruginous soil. Ten treatment combinations comprising two cucumber varieties and five levels of s...
Crops are faced with several definite environmental stresses either concurrently or at different periods during their entire growth and productivity season. Combinational occurrence of stresses and pollution such as salinity stress and crude oil pollution is destructive to crop growth and productivity than these stresses occurring separately at different crop growth. This research was aimed at showing different stress combinations (salinity stress and crude oil pollution) and their impact on ...
