    Copper in water-soil-plant interactions: food chain toxicity due to irrigation with Asa River in Ilorin, Nigeria
    (Department of Agronomy, Nasarawa State University, Keffi., 2017-12-24) Ahamefule, Henry Emeka; Eifediyi, E.K.; Olaniyan, J.O.; Amana, Sani Mathew; Akah, Nkechi; Ihem, E.; Yusuf, Abdulateef; Taiwo, Ridwan
    Asa River is the most important river that serves as a cheaper and easier disposal alternative to industries and at the same time as a less expensive and dependable water supply to farmers for the production of vegetables in dry season in Ilorin, the capital city of Kwara State, Nigeria. To investigate the effect of Asa River water pollution on water-soil-plant copper (Cu) mobility, a two factor factorial in randomized complete block design (RCBD) survey was conducted. The factors comprised of Factor A: distance between irrigation water sources and Factor B: irrigation history (irrigation duration in years). Four (4) farming locations, which corresponded to a control location 200 m upstream (– 200 m location), 200, 400 and 600 m downstream were selected. At each location, 4 farmers with different irrigation history were selected and the study was replicated thrice. The irrigation history was 0, 10, 20 and 30 years of irrigation with Asa river water. The results indicated that Cu levels in Asa River obtained 600 m downstream of control location, exceeded permissible limits with levels as high as 4.51 mg/L. Soil and plant tissue Cu concentrations were also found to exceed permissible levels, with plant tissue Cu reaching as high as 81.86 mg/kg in Corchorus olitorius.

    Salinity Status of Osere River for Irrigation: Long Term Use Implication in Selected Farmers
    (Department of Agronomy, Nasarawa State University, Keffi., 2019-03-29) Ahamefule, Henry Emeka; Taiwo, Ridwan; Amana, Sani Mathew; Eifediyi, E.K.; Ezuogu, Betsy; Ihem, E.; Nwokocha, C.C.; Yusuf, Abdulateef; Fatola, Fatai; Adepoju, S.
    Osere River is one of the important rivers that serves as a cheaper and easier disposal alternative to industries and at the same time a less expensive and dependable water supply to farmers for dry season vegetable production in Ilorin, the capital city of Kwara State, Nigeria. The edaphic aftermath of the use of its water for irrigation was investigated using a Randomized Complete Block Design (RCBD) in a two way factorial experiment. Factors comprised of fifty meter distance intervals (50 and 100 m) downstream and a control (50 m upstream) of a soap industry effluent discharge point and irrigation duration (0, 10, 20 and 30 years). River water samples indicated that the activities of the soap industry did not lead to its increased electrical conductivity (which signifies presence of dissolved salts and/or impurities), however soils under prolonged irrigation (up to 10 years) showed signs of salt induced structural deterioration (MWD). Farm soils 50 m downstream showed the lowest structural stability (MWD = 0.77 mm)and highest % silt of 21.2 whereas those located 100 m downstream indicated highest MWD of 1.10 mm. The consequent soil structural degradation was tied to elevated values of sodium adsorption ratio (SAR) following prolonged irrigation
