The experiment was carried out to establish the rate of decomposition of Acacia mangiumleaf litter and determine the correlation between the stand age and decomposition rate ofits litter.Litter decomposition rate of Acacia mangium under monoculture plantation was studied using the wire mesh frame technique. Wire mesh frames containing 200g of fresh Acacia mangium leaves were set up in three Acacia mangiumstands of ages five, seven and nine years. Ten wire mesh frames were left in each stand using Completely RandomizedDesign.The decay rate coefficient “k” was used to determine the constant potential weight loss of the dry matter. The value of kwas estimated to be 0.0064, 0.0049 and 0.0039 for the 30 th , 60 th and 90 th days respectively, with overall mean of 0.0050 for all the stands. The Half-life estimated for all the stands was 140 days. Analysis of Variance at 5% significant level indicates significant difference between stand age in weight losses on the 30 th and 60 th daysbut no significant effect between the 60 th and 90 th days of observation; there were differences in the decomposition rate between the Acacia mangium leaf litter on the seven and nine years stands.","PeriodicalId":7409,"journal":{"name":"Agriculture and Biology Journal of North America","volume":"27 29","pages":""},"PeriodicalIF":0.0,"publicationDate":"2013-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91446164","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}

Fifteen male rats weighing 230-250g were completely randomised into three groups: A-C. Animals in Group A (control) were orally administered with 0.5ml of distilled water once daily for 21 days while those in Groups B and C, received 500 and 1000mg/kg body weight of the extract respectively), and effect of the treatment on the testes was investigated. Significant increase (p<0.05) were recorded in the body weights and also the weight of the testis. The treatment caused increase in motility, morphology, and number of spermatozoa in cauda epididymidis. Histologically, testes in rats treated with the plant extract showed no alterations in the seminiferous tubules when compared to the control. However hormonal assay showed significantly reduced levels (p<0.05) of FSH, LH and Testosterone in experimental groups while there was increase in the activity of SOD, which was dose dependent. The results thus suggest that C. albidum treatment does not cause suppression of spermatogenesis but decrease the hormonal profile.","PeriodicalId":7409,"journal":{"name":"Agriculture and Biology Journal of North America","volume":"33 1","pages":"160-165"},"PeriodicalIF":0.0,"publicationDate":"2013-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87207584","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}

A total of 1587 specimens were collected from six sites i.e. Dschang (265), Fokoue (253), Fongo – Tongo (267), Nkong – Ni (271), Penka Michel (268) and Santchou (263). Identification of these grasshoppers showed 28 species that included 22 Acrididae and 6 Pyrgomorphidae. The Acrididae belonged to 8 subfamilies (Acridinae, Catantopinae, Cyrtacanthacridinae, Eyprepocnemidinae, Oedipodinae, Oxyinae, Spathosterninae and Tropidopolinae) while the Pyrgomorphidae belonged to only one subfamily (Pyrgomorphinae). The Catantopinae (Acrididae) showed the highest number of species while Oxyinae, Spathosterninae and Tropidopolinae showed only one species each. Ten Acrididae species (Acanthacris ruficornis, Anacatantops sp, Catantops melanostictus, Coryphosima stenoptera, Cyrtacanthacris aeruginosa, Eyprepocnemis noxia, Gastrimargus africanus, Heteropternis sp, Ornithacris turbida, and Trilophidia conturbata ) and one Pyrgomorphidae (Zonocerus variegatus) were collected in all the six sites. Twelve Acrididae and 3 Pyrgomorphidae were collected during the wet and dry seasons. The importance of these grasshoppers in relation to pest activity, necrophagy, entomophagy, and entomotherapy, are discussed.","PeriodicalId":7409,"journal":{"name":"Agriculture and Biology Journal of North America","volume":"164 1","pages":"291-299"},"PeriodicalIF":0.0,"publicationDate":"2013-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80373079","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}

A cross sectional type of studies were conducted to collect data from November 2010 to April 2011 using questionnaire survey and a simple random sampling techniques, 100 households were included in the survey. The main production objectives of chicken were income generation, household consumption and replacement of the flock. And most of the activities in chicken rearing were carried out by women. The average flock size was 10.44 chickens with a range of 2-18 birds. Most of the birds rested at night in a separated confined chicken house. Chickens in the study area were getting their major feed resources through scavenging with little supplementary feed provision. The major causes of losses of chicken in the study area were disease (47%), predation (22%) and mismanagement (31%). According to respondents, the common signs of disease frequently occurred in their flock were watery and yellowish diarrhoea, closing of eyes, head hangs down, high level of morbidity, depression, droppings of wings, sneezing or coughing, nasal discharge, twisting of head and neck, loss of appetite and mass death. The average number of eggs laid by local hen was 11.53eggs/hen/clutch and the hatchability percentage observed in this study was 87.29 %, which ranged from 57.1%-100%. The most important constraints of poultry production in the study villages were disease (1 st ), predators (2 nd ), shortage of supplementary feeds (3 rd ), poultry housing problem (4 th ) and lack of veterinary health services (5 th","PeriodicalId":7409,"journal":{"name":"Agriculture and Biology Journal of North America","volume":"143 1","pages":"192-198"},"PeriodicalIF":0.0,"publicationDate":"2013-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86749784","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 experiment consisted of six treatments laid out in a Randomized Complete Block Design and replicated three times. The data collected were subjected to statistical Analysis of Variance and the treatment means were separated using the New Duncan Multiple Range Test at P< 0.05 level of significance. The results showed that the intercropped maize irrespective of spacing adopted, were consistently superior to the sole maize crop in dry matter production per plant, height per plant, number of leaves per plant and leave area per plant. The best grain yield of 3.78 tonnes/ha was obtained in maize spaced at 75 x 75 cm. The sole ginger crop gave rhizome yield (14.08 tonnes per hectare) was statistically higher than yields obtained in intercropped treatments. The intercropped treatments had yield advantages over the sole crop with maize Land Equivalent Ratio of 23-79%.
