Performance of Roselle (Hibiscus sabdariffa L) as Influenced by Irrigation Schedules
F.E. Babatunde,A.L.E. Mofoke
Pakistan Journal of Nutrition , 2006,
Abstract: Global outcry for food security necessitates both rain fed and irrigation farming to boost up world food production. This research therefore explored the possibility of growing roselle (Hibiscus sabdarriffa. L) under irrigation. The experimental treatments comprised five irrigation schedules with irrigation intervals (f) of 3, 5, 7, 9, and 11 days. The corresponding gross water requirements (GWR) were 37, 56, 74, 93, and 112mm. The crops were grown under check basin irrigation during the 2001/2002 and 2002/2003 irrigation seasons in Bauchi state, Nigeria. Results showed that difference in number of leaves per plant was significant (p = 0.05) with the fifth irrigation schedule (f = 11 days, GWR = 112mm) giving the highest value of 347 leaves per plant, while the first irrigation schedule (f = 3 days, GWR = 37mm) resulted in only 192 leaves per plant. Variations in plant height, number of branches per plant and canopy diameter were insignificant (p = 0.05). The influence of irrigation schedule on the yield of roselle measured with respect to fresh calyx weight was highly significant with a strong coefficient of determination of 97.1%. Yield soared with increase in seasonal irrigation depth. The increase followed a second degree polynomial, reaching a projected maximum of about 682 Kg/ha. The associated maximum seasonal application depth was found to be approximately 3389 mm. Results of this study indicate that maximum yield of roselle grown under irrigation could be attained with a weekly irrigation interval and a gross application depth of 188 mm.

ARKU, A.Y.,S.M. MUSA,A.L.E. MOFOKE
Journal of Applied Phytotechnology in Environmental Sanitation , 2012,
Abstract: The use of local materials as disinfectants in wastewater treatment process is considered important especially in developing countries because of low cost and environmentally-friendly reasons among others. Crude seeds of drumstick (Moringa oleifera) were collected from trees in households and the surroundings in Maiduguri city, north-eastern Nigeria. They were threshed, shelled, milled and sieved to obtain the fine powder. It was then dissolved into clean water and subjected to analysis using Inductively-Coupled Plasma Optical Emission Spectrometry (ICPOES) method giving Iodine value 62.7, Potassium 10.59 mgL-1, Sodium 2.91 mgL-1, Calcium 22.68 mgL-1, Magnesium 0.16 mgL-1 and Phosphorus 2.29 mgL-1. Also, ten levels of concentrations; 0 (control), 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, and 0.9 gL-1 were prepared and standardized in relation to the wastewater needed to be added. Only 0.4 concentration level was used in treating the domestic, agricultural and industrial wastewater samples. The results, when compared with standard values for drinking and agricultural use showed that they could only be used for unrestricted (drip) irrigation but not for drinking.
DETERMINATION OF WATER REQUIREMENTS FOR IRRIGATING HIBISCUS (ROSA SINENSIS) IN MAIDUGURI METROPOLIS
ARKU, A.Y.,S.M. MUSA,A.L.E. MOFOKE
Journal of Applied Phytotechnology in Environmental Sanitation , 2012,
Abstract: Crop water requirements are essential for any water conservation study in crop production. This is particularly important in arid and semi-arid regions where water is increasingly becoming scarce. In this study, theoretical Landscape water requirements for hibiscus (Rosa sinensis) irrigated in Maiduguri metropolis which experiences rainfall only from July to September annually were determined. In order to obtain the landscape water requirement, computations of reference evapotranspiration (ETo), Landscape evapotranspiration (ETL) and Landscape Area (LA) were done using appropriate equations in the Penman-Monteith formula and CROPWAT 8.0 software. Assumptions of factor for the plant species (Ks), microclimate factor (Kmc), plant density (Kd), spacing from standard WUCOLS values and using climatic data from Nigerian Meteorological (NIMET) centre, Maiduguri, Nigeria were also considered. The highest evapotranspiration and water requirements of 6.59 mm.day-1 and 1.19 L.day-1 were obtained in May while the lowest of 3.65 mm.day-1 and 0.66 L.day-1 in December respectively.
RE-EXAMINING RAW EFFLUENTS FROM NIGERIAN BOTTLING COMPANY MAIDUGURI FOR CROP IRRIGATION
ARKU, A.Y.,S.M. MUSA,A.L.E. MOFOKE,J.M. DIBAL
Journal of Applied Phytotechnology in Environmental Sanitation , 2012,
Abstract: Industries are among the heavy users of freshwater globally which implies large volumes of wastewater being generated and discharged. This becomes an environmental threat if not properly handled but can equally be beneficial for agriculture when used effectively. In arid and semi-arid regions where water is scarce, the use of wastewater is becoming increasingly popular. In this study, samples of wastewater and soil were collected from the Nigeria Bottling Company (NBC) in Maiduguri, north-eastern Nigeria; analysed using Inductively-Coupled Plasma Optical Emission Spectrometry (ICPOES), Most Probable Number (MPN), pH and Electrical Conductivity (EC) meters; and compared with previous studies at the site. The results showed that all parameters obtained (pH 6.98, SAR 1.18, Coliform count 92, Chlorine 6.2 meqL-1 and Boron 1.10 mgL-1) were within safe limits and can be recommended for irrigation. Similarly, the soil at the study area was found to be sandy loam (Sand 62%, Silt 20% and Clay 18%) with Infiltration rate (I), 123 mmhr-1, Available Moisture Capacity (AMC), 12.1%, Bulk Density, 1.38 gcm-3, pH 6.4 and Electrical Conductivity of Concentration Extract, (ECe), 3.8 msm-1 which is good for many crops. However, intrusion by stray animals into the earth pond where the wastewater is discharged should be prevented as this is the main source of pollution since the company treats its wastewater within acceptable limits as recommended by Nigerian Environmental Standards and Regulations Enforcement Agency (NESREA) before discharge.
Managing anthelmintic resistance in small ruminant livestock of resource-poor farmers in South Africa : review article
A.F. Vatta,A.L.E. Lindberg
Journal of the South African Veterinary Association , 2012, DOI: 10.4102/jsava.v77i1.331
Abstract: Gastrointestinal parasitism is one of the most important disease complexes of sheep and goats impacting on the resource-poor livestock farmer. Of the responsible nematodes, Haemonchus contortus, a blood-sucking worm of the abomasum, poses possibly the greatest threat. Over the past several decades, the worm has been controlled through the use of anthelmintics, but the emergence of anthelmintic resistance has threatened this chemotherapeutic approach. In Africa, the overall prevalence of anthelmintic resistance has not been extensively investigated, particularly within the resource-poor farming sector, but resistance has been reported from at least 14 countries with most of the reports emanating from Kenya and South Africa and the majority concerning H. contortus. While levels of resistance under commercial sheep farming systems in South Africa is considered to be amongst the worst in the world, resistance has also been reported from the resource-poor farming sector. Increases in productivity and reproduction of livestock and the development of markets for sale of animals are seen by international funding bodies as a way out of poverty for communities that keep livestock. This must lead to the greater need for parasite control. At such times, the risk of levels of anthelmintic resistance escalating is much greater and there is therefore a need to look at alternatives to their use. Proposed strategies include the appropriate, but judicious use of anthelmintics by application of the FAMACHA(c) system and the use of alternatives to anthelmintics such as strategic nutrient supplementation. It is also very clear that there is a strong demand for knowledge about animal diseases, including helminthosis, and their effective management in the resource-poor livestock farming communities. This is an important challenge to meet.

The Effects of Cetylpyridinium Chloride (Cecure CPC Antimicrobial1) on Campylobacter Spp. on Raw Poultry:A Review
A.L. Waldroup,K.L. Beers,P.E. Cook,E.A. Dell
International Journal of Poultry Science , 2010,
Abstract: Published findings have clearly demonstrated that between 0.1 and 0.5%, Cecure is by far the most efficacious antimicrobial treatment available for controlling Campylobacter on poultry carcasses. Safe Foods Corporation’s commercially available pre-chill and post-chill Cecure applications should be fully capable of meeting and exceeding any Campylobacter government regulation that will be issued, regardless of the sampling plan or specific isolation methodology that may be mandated. Safe Foods’ previous laboratory studies and in-plant experience, as well as the published findings of other scientists, suggest that Cecure will be able to achieve at least a 1-2.5 log reduction in Campylobacter levels on pre-chill broilers, with incidence rates being reduced from 80-90% to no greater than 7-9% with a concentration of Cecure between 0.1 and 0.5%. With a post-chill Cecure application, the antimicrobial should virtually eliminate the organism (2-3 log reduction) with an expected incidence rate of no greater than 3-5% at a Cecure concentration between 0.1 and 0.5%.

Brazilian Journal of Medical and Biological Research , 1999, DOI: 10.1590/S0100-879X1999000600004
Abstract: the free form of the iron ion is one of the strongest oxidizing agents in the cellular environment. the effect of iron at different concentrations (0, 1, 5, 10, 50, and 100 μm fe3+) on the normal human red blood cell (rbc) antioxidant system was evaluated in vitro by measuring total (gsh) and oxidized (gssg) glutathione levels, and superoxide dismutase (sod), catalase, glutathione peroxidase (gsh-px) and reductase (gsh-rd) activities. membrane lipid peroxidation was assessed by measuring thiobarbituric acid reactive substance (tbars). the rbc were incubated with colloidal iron hydroxide and phosphate-buffered saline, ph 7.45, at 37oc, for 60 min. for each assay, the results for the control group were: a) gsh = 3.52 ± 0.27 μm/g hb; b) gssg = 0.17 ± 0.03 μm/g hb; c) gsh-px = 19.60 ± 1.96 iu/g hb; d) gsh-rd = 3.13 ± 0.17 iu/g hb; e) catalase = 394.9 ± 22.8 iu/g hb; f) sod = 5981 ± 375 iu/g hb. the addition of 1 to 100 μm fe3+ had no effect on the parameters analyzed. no change in tbars levels was detected at any of the iron concentrations studied. oxidative stress, measured by gsh kinetics over time, occurs when the rbc are incubated with colloidal iron hydroxide at concentrations higher than 10 μm of fe3+. overall, these results show that the intact human rbc is prone to oxidative stress when exposed to fe3+ and that the rbc has a potent antioxidant system that can minimize the potential damage caused by acute exposure to a colloidal iron hydroxide in vitro.

Brazilian Journal of Medical and Biological Research , 1999,
Abstract: The free form of the iron ion is one of the strongest oxidizing agents in the cellular environment. The effect of iron at different concentrations (0, 1, 5, 10, 50, and 100 μM Fe3+) on the normal human red blood cell (RBC) antioxidant system was evaluated in vitro by measuring total (GSH) and oxidized (GSSG) glutathione levels, and superoxide dismutase (SOD), catalase, glutathione peroxidase (GSH-Px) and reductase (GSH-Rd) activities. Membrane lipid peroxidation was assessed by measuring thiobarbituric acid reactive substance (TBARS). The RBC were incubated with colloidal iron hydroxide and phosphate-buffered saline, pH 7.45, at 37oC, for 60 min. For each assay, the results for the control group were: a) GSH = 3.52 ± 0.27 μM/g Hb; b) GSSG = 0.17 ± 0.03 μM/g Hb; c) GSH-Px = 19.60 ± 1.96 IU/g Hb; d) GSH-Rd = 3.13 ± 0.17 IU/g Hb; e) catalase = 394.9 ± 22.8 IU/g Hb; f) SOD = 5981 ± 375 IU/g Hb. The addition of 1 to 100 μM Fe3+ had no effect on the parameters analyzed. No change in TBARS levels was detected at any of the iron concentrations studied. Oxidative stress, measured by GSH kinetics over time, occurs when the RBC are incubated with colloidal iron hydroxide at concentrations higher than 10 μM of Fe3+. Overall, these results show that the intact human RBC is prone to oxidative stress when exposed to Fe3+ and that the RBC has a potent antioxidant system that can minimize the potential damage caused by acute exposure to a colloidal iron hydroxide in vitro.
Antidiabetic and Hypolipidaemic Effects of Ethanolic Root Extract of Setaria megaphylla
J.E. Okokon,A.L. Bassey,L.L. Nwidu
International Journal of Pharmacology , 2007,
Abstract: Evaluation of antidiabetic and hypolipidaemic activity of ethanolic root extract of Setaria megaphylla as well as its acute toxicity was carried. The extract was found to be slightly toxic with LD50 value of 2074.8 mg kg-1. Treatment of alloxan-induced diabetic rats with the extract caused a significant (p<0.01) reduction in fasting Blood Glucose Levels (BGL) of the diabetic rats both in acute study and prolonged treatment (15 days). The activity of the extract was comparable to that of the reference drug, Glibenclamide. Setaria megaphylla treatment showed a considerable lowering of serum total cholesterol, triglycerides, LDL cholesterol, VLDL cholesterol and an increase in HDL cholesterol in the treated diabetic group. This results suggest that the root extract of Setaria megaphylla possesses antidiabetic and hypolipidaemic effect in alloxan-induced diabetic rats.
