MICROBIAL QUALITY AND HYGIENIC PRACTICES OF DRINKING WATER IN JAJA TOWN, EAST HARARGHE ZONE, OROMIA REGIONAL STATE, ETHIOPIA

Abstract: Water is one of the most valuable natural resources, an essential element for life development and human activities (Romeu-Álvarez et al., 2012). The generation of recent information about both the water quality status and sanitation condition is highly important for +intervention. Hence, this study was conducted to assess the quality of drinking water supplied to the residents of Jaja town at the point of water resources well, spring and tap water from January 2021 to June 2022. ...

MICROBIAL QUALITY AND HYGIENIC PRACTICES OF DRINKING WATER IN DHERA TOWN, DODOTA WOREDA, ARSI ZONE, OROMIA REGIONAL STATE, ETHIOPIA

Abstract: Back ground.Water is the essence of life. A clean and safe drinking water supply may be the norm in European and North American countries, but in developing countries the assessment of both clean and safe drinking water (DW) is not the rule and hence waterborne illness outbreaks are common. Objective:This study was conducted to assess the microbiological quality of drinking water collected from different sites in Dhera town during July-December 2022.During this period a total of 42...

Studies on Gene Frequencies of Polyembryony and Karyotype in Fluted Pumpkin (Telfairia Occidentalis Hook. F.)

ABSTRACT Five experiments were performed to investigate the polyembryonic expressions and karyomorphology of fluted pumpkin (Telfairia occidentalis Hook. F.). The results obtained revealed three morphotypes of polyembryony which included twin, triple and quadruple, irrespective of the shape of the pod. The three morphotypes had side shoots that varied in length. Some were unequal, a few of them were almost equal, and many had rudimentary side shoots, which subsequently degenerated with time. ...

FIELD PERSISTENCE OF S-METOLACHLOR AND PENDIMETHALIN IN MAIZE-BASED CROPPING SYSTEM AND IMPACT ON EARTHWORM ACTIVITIES IN OGBOMOSO, NIGERIA

Application of chemicals on weed has been an effective method of weed control. However, this is with problems of persistence and hazardous effects on non-target organisms like arthropods. Common herbicides used in maize fields in Ogbomoso include atrazine, primextra, Lasso/atrazine, diuron pendimethalin, and S-metolachlor. Information on S-metolachlor and Pendimethalin persistence under field situations is inadequate. Therefore, persistence of S-metolachlor and Pendimethalin in maize fiel...

EVALUATION AND INHERITANCE OF SINGLE AND MULTIPLE RESISTANCE TO VIRAL DISEASES OF COWPEA (Vigna unguiculata (L.) Walp)

Cowpea (Vigna unguiculata (L.) Walp) is one of the most economically and nutritionally important indigenous African grain legumes. It is cultivated in the tropics and sub-tropical regions in Asia and Oceania, the Middle East, southern Europe, Africa, southern USA, and Central and Southern America (Singh et al., 2002). It is an annual crop believed to have originated in Africa (Padulosi and Ng, 1997). Cowpea is well adapted to the dry savanna in the West African sub-region, where it is mo...

INTERACTION OF Meloidogyne incognita WITH Botryodiplodia theobromae ON Manihot esculenta (CASSAVA) AND ITS BIOCONTROL

The Root-Knot Nematode (RKN), Meloidogyne incognita and fungus Botryodiplodia theobromae, are important pests that cause yield losses in cassava and other crops. Chemicals have been used to manage these pests but with undesirable side effects. Information on pathogenicity of M. incognita, its interaction with B. theobromae and its biocontrol in Nigeria is very little. Therefore, pathogenicity of M. incognita on cassava, its interaction with B. theobromae and management with biocontrol ag...

EFFICACY OF SELECTED BOTANICALS AND MICROBIAL AGENTS AS ECO-FRIENDLY PROTECTANTS AGAINST Fusarium verticillioides (Sacc.) NIRENBERG EAR-ROT DISEASE OF MAIZE, Zea mays L.

Maize (Zea mays L) is the third most important cereal crop in the tropics (CIMMYT, 2004). It is an important grain crop in the world due to its ability to produce economic yields under the marginal production conditions of low soil fertility and management (FAO, 2005). Total world production of maize in 2011 was estimated at 817,110,509 MT. Nigeria‘s share of the production is 9, 180, 270 MT (FAOSTAT, 2011). It is a food crop of economic significance and nutritional importance in the ...

DEVELOPMENT OF A RAPID URINE-BASED DIPSTICK TEST FOR DIAGNOSIS OF MALARIA

SUMMARY Bloodsmear microscopy is currently the gold standard and the principal test for confirmatory diagnosis of malaria. However, microscopy is labour-intensive and is limited by inadequate sensitivity and specificity.   Apart from microscopy, rapid diagnostic tests (RDTs), which include the quantitative buffy coat test (QBC) and the immuno-chromatographic tests (ICTs) are alternative tests for confirmatory diagnosis of malaria. RDTs, particularly, ICTs are fast gaining momentum as altern...

Potentials of Moringa oleifera Seeds and Aluminium Sulphate as Coagulants for Treatment of Water Samples from Usuma River, Abuja

ABSTRACT The potentials of Moringa oleifera seeds and Aluminium Sulphate as coagulants for the treatment of water samples from Usuma River Abuja was carried out. The physicochemical parameters investigated were the Turbidity (in NTU), Total Dissolved Solids (in mg/l), Conductivity (in μS), and Salinity (in ppm). For the water treatment with Alum, the standard municipal water treatment dosing of 360 mg/l was used. For the treatment with the natural coagulant, there was need to determine t...
