dc.description.abstractA research was conducted to assess the nutritional value and heavy metal uptake of upland rice grown using organic and inorganic fertilizer on an Ultisol at the Centre for Agricultural Research and Extension, Federal University of Technology, Owerri. The experiment comprised of Control (Cl), Urea (Ua) at 400kg.ha-1, Rumen digesta (Rd), Poultry dropping (Pd) and Pig slurry (Ps) at the rate of 40t.ha-1 each. The 5 treatments were replicated five times to give a total of 25 plots. Each plot measured 2×2 m with a 1 m alley between plots. The test crop was CP 306 upland rice variety. The proximate analysis and heavy metal content of the rice grain were conducted. The experiment was laid out in a randomized complete block design. The data resulting from the experiment was subjected to analysis of variance (ANOVA) and significant differences were separated using fisher’s least significant difference at P = 0.05. The nutritional value of the rice (%Mc, %Fat, %Protein, %Fiber, %Ash and, %CHO) showed significant difference when the control was compared with the treatments and when the treatments were compared with one another. The rice grown on pig slurry treated plot had the highest value of % Mc, %Fat, %Protein, %Ash and significantly higher concentration of CHO while the largest % Fiber content was recorded from the rice grain grown on urea fertilizer. The heavy metal content of the rice grain also showed significant difference when the control was compared with the treatments and when the treatments were compared with one another. Relative comparison of these metals with standards showed that none of them were present in concentrations exceeding the permissible limits.
