• W2783235460 abstract "La baisse de fertilite des sols, l’une des principales contraintes du secteur agricole au Togo, sevit encore plus dans la riziculture irriguee ou les terres sont exploitees chaque annee sans jachere. Face a cette situation, diverses solutions comme les technologies de gestion de la fertilite des sols ont ete proposees. Afin d’evaluer le taux d’adoption des technologies et les contraintes d’adoption, une etude a ete realisee dans les perimetres irrigues de la region Maritime aupres de 250 riziculteurs dans quatre villages. Les resultats de l’etude ont montre que les technologies comme l’apport d’engrais, (quatre sacs NPK 15-15- 15 et deux sacs d’Uree 46 %) et l’apport fractionne de l’uree en deux temps sont adoptees a plus de 60 % en raison du niveau de fertilite des sols et de leur pratique peu couteuse. Par contre, le placement profond d’uree et l’enfouissement de la paille du riz ont ete moins adoptes avec un taux d’adoption inferieur a 15 %. Les raisons evoquees sont entre autres le cout eleve des technologies, le manque d’equipements, la penibilite des activites et le manque d’informations. Il ressort donc que les paquets de technologies vulgarisees sont parfois incompletes et repondent peu aux conditions socioeconomiques des riziculteurs.

These falling in soil fertility, the main constraints of the agricultural sector, are even more prevalent in irrigated rice farming where land is harvested each year without fallow. Faced with this situation, various solutions have been proposed, including technologies for the management of soil fertility. In order to determine the rate of adoption of technologies and contraints of adoption, a study was carried out in the irrigated perimeters of the Maritime region with 250 rice farmers in four villages. The results of the study showed that technologies such as fertilizer supply four bags NPK 15-15-15 and two bags urea 46 % and fractional intake of urea in two stages are adopted to more than 60 % in because of the level of soil fertility and their inexpensive practice. On the other hand, technologies such as the deep placement of urea and the burial of rice straw have been very little adopted, with an adoption rate of less than 15%. Reasons evoke are high technology costs, lack of equipment, hardship and lack of information. It thus appears that the packages of popularized technologies are sometimes incomplete and answer little to the socio-economic conditions of rice farmers.
