Abstracts
Water for traditional irrigation on flood-plains in Bauchi State is obtained from the Jama'are, Gongola and Komadugu river systems. The plains are replenished during rainy season and farmers often drill wells to irrigate their farm lands. Wells are drilled by jetting techniques and most of the farmers' plots are less than 1 hectare. Well yield varies from 0.6 to 9.4 Ls-1 and water is drawn from a depth of 12 m. From the mean yield, the results indicate higher water abstraction from tube wells located at Jama'are flood plains. The study recommended appropriately locating wells and greater investment in extension services in order to facilitate the growth of farmer associations.

A água para irrigação tradicional nas planícies de inundação no Estado de Bauchi é obtida a partir de sistemas fluviais Jama'are, Gongola e Komadugu. As planícies são recarregadas durante a estação chuvosa e os produtores rurais muitas vezes perfuram poços para irrigar suas terras. Os poços são perfurados usando-se técnicas de jateamento e os talhões irrigados são em sua maioria menores do que 1 ha. O rendimento dos poços varia de 0,6 a 9,4 Ls-1 e a água é obtida a uma profundidade de 12 m. A partir do rendimento médio, os resultados indicam maior captação de água em poços tubulares localizados nas planícies de inundação do Jama'are. O estudo recomenda a adequada implantação dos poços e a ampliação do serviço de extensão para facilitar o crescimento das associações de produtores.
