Twenty strains of cowpea Rhizobium have been screened to date for their ability to form nodules and to fix nitrogen using the Leonard jar assembly. The strains were tested on Ife Brown, TVu 1190, and TVx 222-01B. From among the twenty, four promising strains were selected. The nodulation and nitr...

In trials carried out to evaluate the effects of applying 0, 40, 80, and 120 kg N/ha on N uptake by intercropped maize and bean, the N content of 4-wk-old bean plants did not differ significantly among N fertilizer levels and cropping systems. However, there were significant differences among bea...

En ensayos para estudiar los efectos de la aplicacion de 0, 40, 80 y 120 kg de N/ha en la absorcion de este elemento por maiz y frijol en asociacion, el contenido de N en plantas de frijol de 4 semanas no presento diferencias significativas entre niveles de fertilizante y sistemas de cultivo. Sin...
