In the present study, a rapid, simple and efficient protocol for in vitro propagation of guava (P. guajava L.) from nodal segments of adult trees grown in the field was established. Explants collected in Autumn and cultured on Murashige and Skoog (MS) medium supplemented with 6-benzyl adenine (BA) at 8.9 μM, plus indole-3-butyric acid (IBA) at 0.98 μM showed the best response in the in vitro establishment (91.7% sprouting percentage and shoot length of 1.75 cm). In addition, 100 mg/l ascorbic acid and 150 mg/l citric acid as antioxidants and Polyvinylpyrrolidone (PVP) at 100 mg/l and activated charcoal (AC) at 2 g/l as absorbents were added to the establishment medium to reduce phenolic compounds. Regarding average number and length of shoots per explant, BA was more effective than kinetin (kin). Maximum rooting percentage (66.7%) occurred on solid halfstrength MS medium containing indol-3-butyric acid (IBA) at 9.8 μM. Fifty percent (50%) rooted plantlets were successfully acclimatized in the greenhouse in soil mixture of sand, grand soil and peat moss at equal volumes, and subsequently established outside the greenhouse.","PeriodicalId":14496,"journal":{"name":"IOSR Journal of Agriculture and Veterinary Science","volume":"16 1","pages":"28-35"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74486831","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}

It specifically examined respondents enterprise profitability, the socio-economic determinants of output, production system and constraints to production. Multi-stage and random sampling procedure were used in selecting 120 respondents from three of the five states in the region. Pre-tested questionnaire was used as instrument for data collection while descriptive statistics, enterprise budgeting and multiple regression were used for data analysis. Findings showed that majority (67%) of the respondents were males, 75% were married with mean household size of 5 persons and mean educational attainment of 8 years. Farming systems adopted by the farmers included mixed and continuous cropping, and farm sizes of less than one hectare. Output was significantly and positively determined by educational level, gender, farm size, cost of inputs, number of extension visits and amount of credit obtained. The enterprise was profitable judging by the positive values of gross margin, net farm income, mean net farm income and net return on investment of N1,893,114, N1,705,965, N14,216.38 and 0.39 respectively. Production was majorly constrained by high cost of labour, low acceptability and demand of product, lack of improved varieties as well as poor technical know-how. Research institutes should focus efforts on upgrading the yield and quality of the variety while government provides enabling incentives to the extension agencies and farmers, to enhance their outputs and ensure improvement in product supply and acceptability.","PeriodicalId":14496,"journal":{"name":"IOSR Journal of Agriculture and Veterinary Science","volume":"41 1","pages":"13-18"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81758954","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}

When the production of ROS increases or the scavenging systems are ineffective, the result is an excess of these free radicals, leading to a condition called oxidative stress.ROS damage DNA, biomembrane lipids, proteins and other macromolecules. These phenomena contribute to the development of several metabolic dysfunctions, including cell death by causing “oxidative stress” and “oxidative damage.The detrimental effects of high ambient temperature on broiler performance have been widely documented. Feed consumption and growth rate decrease at high ambient temperature. Antioxidant status of the organism is depleted as result of heat induced oxidative stress The degree of lipid peroxidation is used as an indicator of ROS mediated damage and the concentration of MDA in blood and tissues are generally used as biomarkers of oxidative stress. In addition analyses of the activity of the enzymes glutathione peroxidase, catalase and superoxide dismutase are important in determining whether oxidative stress reactions are induced in cells and which cells or organs have been damaged. Antioxidants like ascorbic acid are free radical quenchers,and thereforealleviate the negative effect of heat stress and may stimulate the biosynthesis and secretion of antioxidant enzymes which scavenge the free radicals.","PeriodicalId":14496,"journal":{"name":"IOSR Journal of Agriculture and Veterinary Science","volume":"37 1","pages":"41-44"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87567809","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}

Development of communities is a continuous process in order to sustain communities through utilizing their assets in a world that is increasingly becoming unpredictable and difficult in terms of togetherness and caring concerns for sustainability. The paper looked first at rural communities and the way social capital is built and utilized positively for community development despite lots of challenges. Social capital in agriculture was reviewed from rural community perspectives and seen as a motivating and gluing force for communitarian work that benefits the agriculture. The development of social capital as unseen capital in any society will provide the community members the force to forge ahead in whatever self-help endeavor their community resolved to undertake. The paper also considers the other side of the coin and looked at marginal community members that did not subscribe to social capital and became excluded from the beneficial collective actions of the majority. The paper lastly, posits that social capital in agricultural communities will go a long way in empowering community members to sustainably produce food and develop their communities.","PeriodicalId":14496,"journal":{"name":"IOSR Journal of Agriculture and Veterinary Science","volume":"62 1","pages":"07-10"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84931571","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}
