Adoption of Recommended Agrochemical Practices among Crop Farmers in Kaduna and Ondo States, Nigeria

This study assessed the level of adoption of recommended practices of agrochemicals among crop farers in Kaduna and Ondo States of Nigeria. It measured the perception of farmers on pesticides and their knowledge on the harmful effects of pesticides. A total of 260 crop farmers who have sustained the use of agrochemicals for at least five years were selected for the study using multi-stage sampling technique. Descriptive statistics (mean and percentages) was used for data analysis. Data was collected using pretested, structured interview schedule. The results obtained revealed that the perception of 33.1% of the farmers was considering pesticides as always good whereas 30% of the farmers perceived pesticides as sometimes harmful. All (100%) respondents indicated that pesticides cause damage to human health. Furthermore, the level of adoption of recommended agrochemical practices (RAPs) was generally low (weighted mean =1.49) despite high level of awareness (weighted mean =2.24). This study therefore, recommends that campaign for attitudinal changes on the use of agrochemical should be mounted by extension agencies in collaboration with relevant stakeholders.   Â

Modélisation et simulation bi et tridimensionnelles de la dynamique unilatérale des systèmes multicorps de grandes tailles (application aux milieux granulaires)

MODELISATION ET SIMULATION BI ET TRIDIMENSIONNELLES DE LA DYNAMIQUEUNILATERALE DES SYSTEMES MULTICORPS DE GRANDES TAILLES : APPLICATION AUX MILIEUX GRANULAIRES Les systmes multicorps sont omniprsents dans la nature et l industrie (pharmaceutique, automobile, etc..). Ceci justifie l intense activit de recherche qui leur est consacre. Pour les tudier, on a commenc par des essais de laboratoire puis des simulations numriques. C est ainsi que sont apparues les mthodes des Elments Finis (EF) et des Elments Discrets (ED). Au niveau des ED, il y a les Smooth DEM et les Non-smooth DEM. Dans notre travail, nous nous intressons aux Non-smooth DEM en 2D et en 3D. Nous avons tabli les quations du mouvement des corps. La loi de contact est exacte, modlise avec le formalisme du bipotentiel de contact initi par De Saxc et rsolue avec l algorithme d Usawa. La dtection des contacts est base sur un maillage fixe et uniforme qui utilise des tables de connectivit. Tout ceci a abouti un code de calcul appel MULTICOR . Ensuite, nous avons valid ce code puis nous avons procd des applications numriques sur les matriaux granulaires secs et cohsifs. La visualisation de tous ces rsultats s est faite grce l interface graphique base sur OPENGL que nous avons mise en place.AMIENS-BU Sciences (800212103) / SudocSudocFranceF

Agricultural Extension Systems in West Africa: Adoptable Strategies for Nigeria’s Agricultural Extension Reform Agenda

National agricultural extension and advisory systems have undergone major changes during the past two decades. These changes have been attributed to the success of the Green Revolution, commercialisation of agriculture and trade liberalization. In addition, transnational corporations develop a wide range of new technologies, which directly impact on agricultural production in developed and developing countries. As more and more production technologies become “private goods” and as an increasing percentage of farmers become commercialized producers, advisory services associated with these specialized technology transfer become progressively sophisticated to enhance its efficiency and effectiveness. This necessitates a policy reform that can accommodate the current scenario in the Nigerian quest for rural development. This paper examines the agricultural extension systems in some West African countries for possible adaptation and adoption in Nigeria’s agricultural extension policy reform. Key words: Agricultural extension systems, local development planning, reform agenda

Evaluation quantitative des résidus de pyréthrinoïdes, d’aminophosphate et de triazines en zones de production de coton au Bénin par la méthode ELISA en phase liquide: Cas des eaux de la rivière Agbado

Le présent travail réalisé au Bénin dans la commune de Savalou, a consisté en une recherche de résidus de pyréthrinoïdes, d’aminophosphates et de triazines dans l’eau et les sédiments de la rivière Agbado par la technique ELISA (Enzyme-Linked Immuno Sorbent Assay) en phase liquide. Quatre campagnes d’échantillonnage ont été menées dont deux en saison sèche et deux en saison pluvieuse. Au total quatre sites d’échantillonnage ont été explorés. Il s’agit de Mèdétèkpo, du Barrage de la Société des Eaux du Bénin, de la Station de traitement d’eau et du grand pont de Gobada. En saison sèche, aucun des résidus recherchés n’a été détecté dans l’eau. Dans les sédiments, les teneurs varient de 0,10 à 0,39 ppb pour le glyphosate et de 0,22 à 0,97 ppb pour l’atrazine. En saison pluvieuse, dans l’eau, les taux varient de 0,05 ppb à 0,475 ppb pour l’atrazine, de 0,10 à 1,316 ppb pour le glyphosate et de 0,75 à 4,450 ppb pour les pyréthrinoïdes. Dans les sédiments seul le glyphosate a été détecté jusqu’à un taux de 8,62 ppb. En moyenne ces valeurs sont supérieures aux normes de qualité de l’eau de boisson admises par l’Union Européenne. Face à ces niveaux de contamination, il importe que des mesures correctives soient prises.Keywords: Contamination, eau, sédiments, Résidus de pesticide
