Cow dung as a feedstock in this work contributed to environmental pollution. However, converting it to useful product for soil amendment justified the research problem. Therefore, this work was aimed at developing biofertilizer from composted cow-dung. This was achieved by mixing 6 kg of cow dung with 1 liter of water for 30 minutes, after which it was transferred into the digester. The pH, moisture content and temperature of the composting system were monitored and recorded at every two days interval for the period of 30 days. The composted product was then discharged, drained and dried with net bag in an open air. Then, 1 kg of brown sugar was dissolved in 2 liters of water for fermentation process. The solution was covered and sealed tightly to stand for 30 days. The liquid solution obtained was subjected to biochemical analysis to identify the active strains of microorganism present. The fermentation product was added to the dried compost product in the digester, covered and left to stand for 15 days. The product was discharged and sample was taken for proximate/quality control analysis. The results showed that, the developed biofertilizer contained carbon to nitrogen ratio of 9.8: 1, 0.28 % nitrogen, 0.0099% phosphorus and 0.048% potassium contents. It also has a pH value of 7.1, moisture content of 40 % and the presence of Bacillus SP with cell a count of 4.3 x 107 cell/g. It was therefore concluded that, the biofertilizer developed met the requirement for crop growth and can be used for soil amendment. \u0000Keywords: Biofertilizer, cow-dung, composted, quality control analysis.","PeriodicalId":128977,"journal":{"name":"Science Forum (Journal of Pure and Applied Sciences)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116623126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The liquid line of descent in the harkrer variation diagrams, indicate that the magma that crystallized to give the Ningi complex is of mantle origin with one or more levels of contamination. The plot of Fe2O3 and TiO2 against SiO2 gives a trend showing instant initial decrease probably indicating fractional crystallization of earlier formed crystals, like Titano-magnetite at higher temperature. The younger granite complex emplacement was accompanied by alteration and enrichment with some elements of interest. The complex shows potash metasomatism which is not uniform across the complex. It is more prominent towards the north-western part of the complex, around Zidangan Fulani area. The plots of K2O against SiO2, SiO2-Na2O-K2O and Al2O3-CaO-K2O also indicate potash enrichment. This suggests that, the crystallizing fluid towards that area interact with the country rocks at higher temperature.

Groups 1 and 2 were fed diet containing 100g and 50g leaf powder of the evaluated material per Kg of feed respectively. Group 3 was treated with 0.3g (preventive dose) of AmproliumR per liter of drinking water while group 4 was left without treatment. The test substance given especially at the rate of 100g demonstrated efficacy in decreasing oocysts shedding, minimizing diarrhea, alleviating caecal damage and lowering morbidity caused the parasite but less than the conventional drug. However, its effect in reducing blood loss and mortality was almost similar that of the standard drug (P≤0.05). Although the test material had slight negative effect on feed consumption and weight gain but it can still be used for prophylactic control of coccidioisis especially when there is resistance to conventional anticoccidial drugs or where they are not available or affordable.","PeriodicalId":128977,"journal":{"name":"Science Forum (Journal of Pure and Applied Sciences)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132327414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Flowers of cowpea opened from 6:00 hr. to 13:00 hr., daily. A total of 388 open flowers and 256 insect visitors were recorded during the seven-day period of the study. 52.3% of the visitors belonged to the order Hymenoptera (honeybees, wasps and ants), 26.2% to Lepidoptera (butterflies and moths) and 21.5% to Diptera (flies). Among the hymenopterans, 42.3% were honeybees, 40.9% ants and 16.8% wasps. The results of this study suggest that, in every hour, approximately 47,000 insect pollinators (including 9,800 honeybees) were exposed to insecticide, in every hectare of flowering cowpea, if spraying was done between 6:00 hr. and 13:00 hr. Thus, to minimise the impact of insecticides on these beneficial insects, cowpea fields should be sprayed from 14: 00 hr. and beyond.","PeriodicalId":128977,"journal":{"name":"Science Forum (Journal of Pure and Applied Sciences)","volume":"248 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132730202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study determined the distribution of the five sunbird species (variable sunbird, scarlet-chested sunbird, green-headed sunbird, copper sunbird and pygmy sunbird) known to exist within the Amurum Forest Reserve. Distribution was determined both within and outside the Amurum Forest Reserve and across the habitat types in the area (gallery forest, savannah scrub and rocky outcrop) and anthropogenic scales (roads, houses and farmlands). The study was conducted between September to October 2014 using presence and absence data. A total of 60-sample points were selected using stratified random sampling. The presence or absence of the candidate bird species was determined across all points after two visits. The study revealed the variable sunbird, Cinnyris venustus as the most widely distributed of the five sunbird species this sunbird species also occurred across all habitat types equally as compared to the scarlet-chested sunbird, Chalcomitra senegalensis which was more skewed in distribution towards the rocky outcrop areas of the reserve. The sunbirds also appeared to utilise areas of anthropogenic disturbance when outside the reserve perhaps due to the presence of several green areas outside of the reserve. The uneven distribution of the birds across the landscape may as a result of niche partitioning to avoid competition. Also, lack of presence of the other sunbird species throughout the period of study was linked to their migratory behavior as reported in some literatures. The study re-emphasizes the importance of the Amurum Forest Reserve as a good refuge for birds in the area.","PeriodicalId":128977,"journal":{"name":"Science Forum (Journal of Pure and Applied Sciences)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129690318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
