After defining a topographic position of the cassava fields encountered, the soil composite samples were taken in 0-40 cm depth. Pits were opened on the slope and the profiles were described therein. The subsoil is most frequently used for the production of cassava, the main crop in these two regions. The results of analysis showed that the soils are chemically poor. The pH was strongly acidic, causing the problem of solubilization of the aluminum ions in soil solution as well as phosphorus availability. In addition, organic matter levels were low overall threatening the increase of the productivity of crops unless applying fertilizers. Soils can be described as of poor quality and almost unfit for sustainable cassava production according to its relatively demanding in organic matter.","PeriodicalId":7409,"journal":{"name":"Agriculture and Biology Journal of North America","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79398562","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 experiment was conducted to determine potential of potato clones with multiple virus resistance in minimizing virus related crop losses. The trials were conducted in two sites for four successive seasons of re-using seed tubers. The genotypes were exposed to natural sources of virus infection without spraying insecticides to control (aphids) virus vectors. Genotypes with multiple virus resistance experienced significant (P ≤ 0.05) lower rate of yield loss (21.2 %) compared to the major local varieties (68.4 %). There was successful identification of a higher yielding virus resistant clone (CIP396286.7) with significant (P ≤ 0.05) higher mean yield (30.3 T/ha) compared to the highest yielding local variety (24.3 T/ha), Tigoni. The number of tubers per plant was significantly (P ≤ 0.05) higher (12.1) in the virus resistant clones than in the local varieties (7.3). Reduced rate of yield loss, higher yield performance and higher number of tubers per plant in the tested clones was attributed to genetic contribution of multiple virus resistance. Virus related crop losses currently experienced by local farmers can be minimized with use of such virus resistant genotypes.","PeriodicalId":7409,"journal":{"name":"Agriculture and Biology Journal of North America","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88329653","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 experimental design adopted was a 4 x 4 x 2 factorial split-plot design; representing the four cultivars, four different ripening stages (Mature Green, 50% ripe, 75% ripe and 95% ripe) and two harvest intervals. Three fruit samples of the individual cultivars selected from each plot at the different ripening stages were evaluated for some quality parameters [fruit water loss(WL), fruit fresh weight (FFW), decay, total soluble solids (TSS), dry matter content (RDM), pericarp thickness (PTK), membrane ion leakage (EL) and fruit firmness (FF)]. The results showed that, Rendo at matured green and 50% ripe stages were outstanding in all the parameters examined, due to its good characteristics such as low water loss, high firmness, low membrane ion leakage and relatively thick pericarp tissue. These results suggest that Rendo could be grown by farmers in even distant areas that have problems with storage facilities, transportation and bad road network since it possesses properties which can prolong its shelf life.","PeriodicalId":7409,"journal":{"name":"Agriculture and Biology Journal of North America","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90784009","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 major objective of this study was to have knowledge on the socio – economic indices, fishing gear, local name and fishing methods involved in shrimp fishing in the 3 states. Data on the socio – economic indices of the fisher folk’s were obtained through structured questionnaires and personal interviews. The data obtained revealed that shrimp fishing was mostly the profession of the young persons (Age 21 – 40 years) and the educational level of the fisher folks was high in the 3 study area with most of the fisher folks attaining mostly up to secondary school education and tertiary education in the areas. Ganaja having a value of 57.14% of fisher folks that attained tertiary education, 69.23% as the highest value of fisher folk’s that attain secondary school in Idah and 46.15% as the highest value of fisher folk’s that attain primary school education in Makurdi. The fishing method employed commonly in the areas of study was the use of basket and sticks and the use of fishing traps. The shrimps were sold at varying prices ranging from ₦120.00 per milk cup ₦5,000.00 for half a big basin in the study areas.","PeriodicalId":7409,"journal":{"name":"Agriculture and Biology Journal of North America","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84782815","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}
