  • Mode of Biochar Application to Vertisols Influences Water Balance
           Components and Water Use Efficiency of Maize (Zea mays L.)

    • Authors: J. B. A. Nyasapoh, S. G. K. Adiku, D. S. MacCarthy, S. A. Yanore
      Pages: 1 - 12
      Abstract: Vertisols belong to a group of soils with high fertility but poor physical properties of swelling when wet and shrinking and cracking when dry. The swelling inhibits infiltration, resulting in flooding, limiting the production of upland crops. Biochar (<BC) application has been shown to reduce the shrink-swell behaviour of Vertisols. However, the mode of biochar application to these soils may affect the effectiveness of the amendment. This study investigated the water relations and maize (Zea mays L.) growth under two BC application modes: (i) biochar applied into cracks that develop with drying, C, and (ii) biochar that was surface broadcast and incorporated into the topsoil, FM. A control treatment did not receive any BC amendment. Maize was grown on the BC-amended Vertisols using the two modes of application in a greenhouse under two seasonal water regimes of 610 and 450 mm. The results showed that the proportion of total water application lost to runoff was 37%, 49% and 53% for C, FM and control treatments, respectively. Both maize yield and Water Use Efficiency (WUE), for the C treatments were significantly (p < 0.05) higher than those for FM treatments. The maize yield under the C treatments was 19% over the control. Similarly, the WUE for the C treatments was 28% above the control treatment. It is concluded that the application of biochar into cracks is a more effective way of improving the water relations and upland crop productivity and WUE in Vertisols than the traditional surface incorporation.

  • Health risk assessment and source identification of Polycyclic Aromatic
           Hydrocarbons (PAHs) in commercially available singed cowhide within the
           Greater Accra Region, Ghana

    • Authors: C. K. Tay, L. K. Doamekpor, S. Mohammed, G. Dartey, R. Kuddy, E. Fianyaglo, M. Mawuena
      Pages: 13 - 34
      Abstract: This study ascertains the sources and potential carcinogenic threats of polycyclic aromatic hydrocarbons (PAHs) in singed cowhide. The objective was to assess the sources of PAHs and the health threats singed cowhide possess to the consuming public. A total of fifty-four (54) cowhide samples from selected markets within the Greater-Accra Region of Ghana were analyzed using Agilent GC 6890N, MS5975B Series gas chromatography in a splitless mode. The study shows that, singed cowhide within the Greater Accra Region is dominated by positive genotoxicity PAHs classified as carcinogens (1) and possible carcinogens (2B) as well as positive and questionable genotoxic PAHs that are not classifiable (3). The [B(a)P]eq and PEC results suggest that consumption of singed cowhide at the rate of 25.2 g/day poses potential adverse health effects such as cancer, mutations and birth defects in terms of B(a)P to humans. Results further show that, the HQ/HI < 1, thus, there is no concern for potential human health risks caused by exposure to non-carcinogenic PAHs in singed cowhide. However, the carcinogenic toxic equivalent (TEQs) values for both adults and children were greater than the screening values and therefore, there is concern for potential human health risks caused by exposure to carcinogenic PAHs in singed cowhide. Source assessment of PAHs in singed cowhide shows that, PAH sources in singed cowhide is predominantly from pyrolitic rather than petrogenic origins. Thus, the PAHs in singed cowhide within the Greater Accra Region originate primarily from incomplete combustion and of petroleum origin due to singeing.

  • Improving Soil Productivity and Increasing Lowland Rice Yields through the
           Integration of Organic and Inorganic Fertilizers in the Savannah and
           Forest Agro-ecological Zones of La Cote d’Ívoire

    • Authors: M. M. Buri, R. N. Issaka, A. Zoromi, E. O. Adjei, T. Wakatsuki
      Pages: 35 - 47
      Abstract: Sole mineral fertilizers use by poorly resourced farmers for rice production in the lowlands is usually low and unsustainable. Field experiments were therefore conducted within two contrasting environments (Forest and Savannah), using two common organic amendments (Poultry manure and Cattle manure) to establish an effective and integrated soil nutrient management system for improved lowland soil productivity and increased rice yields. The study was also partly intended to encourage and promote the effective and sustainable use of locally available organic amendments for nutrient management in lowland rice production. Results showed that organic amendments {cattle manure (CM) and poultry manure (PM)} contributed significantly to grain yield increases and total productivity with PM having a significantly greater and positive effect on grain yield than CM. In addition, the application of organic amendments in combination with mineral fertilizer significantly contributed to increased grain yield over the application of sole mineral fertilizer. Within the savannah agro- cological zone, there was a 130% (CM) and 203% (PM) grain yield increase over the control due to the application of organic amendments . When organic amendments were applied in combination with mineral fertilizer (MF), grain yield increased by 21% and 43% over sole MF for CM and PM respectively. However, sole CM contributed 12% increase in grain yield over the control while PM gave a 35% increase within the forest agro- cological zone. The combined application of MF and CM resulted in an 11% increase in grain yield while MF and PM combinations produced a 30% yield increase within the ecology. The non-addition of N, P, K as mineral fertilizer resulted in a yield reduction of about 84% at both sites. Resource poor farmers within the West African sub-region should therefore be encouraged to use organic amendments, which are not only available locally but also affordable. Proper storage and handling of these organic materials is very important to minimize nutrient losses.

  • Spatial and Seasonal Concentration of Glyphosate, Nitrate, and Phosphate
           in Kuti Stream, Yaba, Abaji Area Council, FCT Abuja, Nigeria

    • Authors: D. Echude, S. I. Ahmad, T. I. Egbeja, L. S. Egwu, C. I. Umoru, I. A. Abubakar, J. A. Adakole, C. E. Mbah
      Pages: 48 - 57
      Abstract: This study determines the concentration of glyphosate (C3H8NO5P), nitrate (NO3-), and phosphate (PO43-) in Kuti stream, Abaji area council, Federal Capital Territory Abuja, Nigeria, for twelve months (January-December, 2019) at four sampling stations that were 500 m apart. Samples were collected monthly during the morning hours (06.00-10.00 h) from a depth of 5–10 cm below the water surface using high-density polyethylene bottles and analyzed by adopting standard protocols. Samples analyzed for C3H8NO5P concentration were pooled quarterly with the highest (0.27±0.01 mg/l) concentration observed in July-September at station 2, lowest (0.02±0.01mg/l) in January-March at station 4. Seasonal concentration differed significantly (P ≤ 0.05), rainy season had 0.12mg/l, dry season had 0.06 mg/l. NO3 - and PO43- had their highest concentration (1.82±0.01mg/l; 0.87±0.01mg/l) in June at station 2 and 1, lowest (0.23±0.06mg/l; 0.21±0.05mg/l) in January and December at station 4 and 3. Rainy season had high concentration (1.82±0.01mg/l; 0.87±0.01 mg/l) of NO3- and PO43- compared to dry season (0.23±0.01 mg/l; 0.21±0.01mg/l). Pairwise correlation coefficients show a strong positive relationship (r=0.53/1.00) between PO43- and C3H8NO5P. The mean concentration of C3H8NO5P, NO3- and PO43- (0.09±0.01 mg/l; 0.59±0.04 mg/l; 0.37±0.02 mg/l) were below the maximum contamination limit (MCL) of 0.7 mg/l, 50 mg/l and 5.0 mg/l by USEPA, WHO and NERN. The high concentrations observed in the rainy season and station 2 were linked to runoff and riparian agriculture, though their mean concentrations were low if not monitored, will increase and become harmful to aquatic and human lives, therefore, conservation farming was suggested.

  • Phenotypic and Phylogenetic Characterization of Micro-symbionts Nodulating
           Winged Bean (Psophocarpus tetragonolobus L. DC.) Landraces

    • Authors: A . R. Oloyede, O. O. Oyelakin, S. O. Ogunesan
      Pages: 58 - 67
      Abstract: Winged bean (Psophocarpus tetragonolobus L.) is a potential source of protein for the tropics and almost equivalent to protein content of soybean. However, information on winged bean-bacteria association is still limited. This study was conducted to assess phenotypic and genetic characterization of micro-symbionts that could effectively nodulate winged beans. The greenhouse experiment was performed in a completely randomized design with five accessions of winged bean and five replicates. The micro-symbionts were isolated from the root nodules and subjected to nodulation test on host plants. The effective nodulating isolates were characterized by phenotypic characteristics and 16S rRNA gene sequencing technique. The strains were also assayed for plant growth promotion traits. Thirty micro-symbionts were isolated from root nodules of winged bean plants but only twelve (40.0%) effectively nodulated their host plants. All the effective microsymbionts were Gram negative, rod-shaped bacteria. Six of the effective rhizobia isolates were slow growers while others were fast growers. The results further showed that four of the isolates could produce ammonia and indole acetic acid, as well as solubilizing phosphate. The phylogenetic analysis revealed that the micro-symbionts were similar to strains of Rhizobium, Bradyrhizobium and Mesorhizobium. The study therefore showed the potential of these micro-symbiont strains in nodulating winged bean.

  • Overlooked Influence of Indian Hemp (Cannabis sativa) Cultivation on Soil

    • Authors: J. Kolo, M. E. Ukabiala, U. C. Osakwe, J. B. Parah, K. Nyamapfene, S. E. Obalum, A. M. Hassan, P. C. Nnabude, C. A. Igwe
      Pages: 68 - 81
      Abstract: One agricultural practice that may be depleting plant nutrients in wetland soils of the humid tropics is cultivation of Indian hemp (Cannabis sativa), also called Marijuana. Though Nigerian Law, adopted from International Conventions on narcotics, prohibits handling of any part of cannabis plant, it is still illicitly cultivated. This practice may be undermining the quality of wetland agroecosystems. To support these concerns with empirical data, the influence of Cannabis cultivation on soil physicochemical fertility of wetland agroecosystems was assessed at a representative location in southwestern Nigeria. The study compared four land-use options; land not used for Cannabis cultivation (NUC), land currently under Cannabis cultivation (CCC), farmlands converted from Cannabis to alternative use (CAU), and Cannabis farmlands abandoned or seized (ABS). Soil data from the pedogenetic horizons under these land-use options were averaged and analysed. There were significant differences in soil bulk density, with low values in NUC (1.36 Mg m–3) < medium values in CCC (1.55 Mg m–3) < high values in both CAU and ABS (1.62-1.66 Mg m–3). The highest value in the ABS (1.66 M  m–3) is slightly above the critical limit (1.60 Mg m–3) for root growth. Soil compaction in Cannabis farmland thus worsened even after discontinuation of cultivation. Soil pH, soil organic C, total N, exchangeable Ca, exchangeable Mg, apparent and effective cation exchange capacity also differed thus NUC ≥ CCC ≥ CAU ≥ ABS, while base saturation showed an inverse trend. Available P was, however, higher in CCC (14.32 mg kg–1) than the rest, with lowest values in ABS (5.83 mg kg–1). Micronutrients (Mn, Zn and Cu), excluding Fe which was unaffected, followed the trend of soil pH. It is concluded that continuous cultivation of Cannabis in humid tropical lowlands compacts the soil and drains soil nutrients except available P whose status is rather elevated. The practice thus poses a threat to food security and ecological well-being.

  • Water Quality Status Within The Anchorage Space of Tema Harbour, Ghana

    • Authors: E. Klubi, S. Addo, K. Appeaning-Addo, K. A. Agyekum
      Pages: 82 - 96
      Abstract: Marine pollution is attributable to anthropogenic introductions of contaminants above their natural background levels and being dispersed by ocean forcing. Assemblages of vessels within offshore platforms and seaport terminals could also be potential sources for marine water contamination. As such, nearshore perimeters of the Tema Port were assessed to review the vessel register and the seawater quality through Automatic Identification System (AIS), in-situ and laboratory analysis. The results of analysed satellite data suggested ~1,600 commercial vessels of over 50 flag states including Ghana were present in the West Africa territorial waters between 2016 and 2020. Bacterial load shows the following order: total heterotrophic bacterial [THB] (364-468 cfu/mL) > total coliform [TC] (26-73 cfu/100 mL) > faecal coliform [FC] (1-13 cfu/100 mL). Phytoplankton species abundances were in order Ceratium spp. (31.8%) >Protoperidinium spp. (30.1%) > Dinophysis spp. (9.3%) > Coscinodiscus sp. (7.3%) > Lingulodinium polyedra (6.9%) = Nitzschia sp. (6.9%). Water temperature ranged between 23.9 and 27.5 oC (surface to 25.4 m depth), salinity 36.03 ± 0.51‰, dissolved oxygen 6.54 ± 0.94 mg/L and pH 8.18 ± 0. 06. Phosphate, ammonia, Cd, As, and Pb levels were low (0.01 to 0.153 mg/L). Nitrate, silicate and Mg were relatively high (0.7 - 2.18 mg/L). Pearson correlation coefficient displayed 0.05 and 0.01 significant levels between total dissolved solids (TDS) and electrical conductivity and salinity, and dissolved oxygen and temperature and arsenic levels. Normalization physicochemical data suggested thermal stratification at 15 m depth. Nutrient and biological results indicated normal water quality conditions, however, relatively high levels of phytoplankton including harmful and toxic species suggested excess nutrient contamination in the study area. Further assessment is recommended to ascertain the link between phytoplankton and nutrient load at the anchorage space.

  • Efficacy of promising insecticides and lures for the management of insect
           pests of quarantine importance on ridged gourd (Luffa acutangula L.)

    • Authors: K. Amouzou, K.O. Fening, W. Hevi, E. E. Forchibe, M.K. Billah
      Pages: 97 - 108
      Abstract: Insecticides play an important role in the management of insect pests on ridged gourd (Luffa acutangula L.) or turia. The sweet potato whitefly, Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae), thrips, Thrips spp. Karny (Thysanoptera:Thripidae), and fruit flies, Zeugodacus cucurbitae (Coquillett) and Bactrocera dorsalis (Hendel) (Diptera:Tephritidae) are the commonly found insect pests on turia in Ghana. These insect pests have been intercepted in some vegetables including turia exported into the European Union. The current study evaluated the efficacy of promising insecticides and lures for the management of these pests of quarantine importance on turia. The study was undertaken at a vegetable production site at Torgorme in the Volta region of Ghana during the dry and rainy seasons of 2017 and 2018, respectively. The experiment was laid out in a Randomized Complete Block Design with five treatments replicated four times. The treatments included use of Eradicoat T GH® (Maltodextrin 282g/L) at 150 ml per 15L of water, Ecopel® (Bacillus thuringiensis 32000 IU/mg at 25g/15L of water, Aqueous Neem Kernel Extract (ANKE) (Azadirachtin) at 50g/L of water, and Viper® (Acetamiprid 16g/l + Indoxacarb 30g/l ) at 40ml /15L of water, and untreated control plot. Fruit fly traps with different pheromones or lures (i.e., Methyl Eugenol, Cuelure, Terpinyl Acetate and Trimedlure) were set at the four corners of the field to monitor the different species of fruit flies. Yellow sticky traps were also set within treatment plots to monitor pest populations. Whitefly population was significantly different among the treatments for both cropping seasons, while fruit fly population was not significant for both seasons. There was a significant difference in thrips population for the rainy season, however, it was not significant in the dry season. In a descending order, Acetamiprid 16g/l + Indoxacarb 30g/l and Azadirachtin were the most effective insecticides in controlling these pests on turia. There is, therefore, the need to alternate these two insecticides for effective management of pests on turia.
