The yield of South African bean lines was assessed in Malawi, using 3 groups with 15 genotypes each. In the 1st trial, carried out in 4 different agroecological zones, Carioca 80 was the best genotype with high yields at all sites (712-1768 kg/ha) and resistant to angular leaf spot and rust. Othe...

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...
