Soil science for bean production
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 bean v...

| description | 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 bean var., the highest N absorption rates being observed in climbing bean var. Kanzama. Bean seed yields increased with higher levels of N. In another trial carried out on the effects of both inoculation and 0, 25, and 50 kg P/ha on biological N fixation in 3 bean var. (Nasaka, P402, and 13-3), effective nodulation was highest when 50 kg P was applied per ha and Rhizobium MG 366 was inoculated. Applying P to inoculated bean seed can significantly increase nodulation and consequently N fixation rate. There were no significant differences in seed yields among treatments; however, P application increased av. seed yields. The best response to inoculation was obtained with P402 (1200 kg seed/ha with 25 kg P). (CIAT) |

(CIAT) 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 embargo, hubo diferencias significativas entre var. de frijol: las mayores tasas de absorcion de N las presento la trepadora (Kanzama). Los rendimiento de semilla de frijol se incrementaron con la mayor dosis de N. En otro ensayo para estudiar los efectos de la aplicacion de 0, 25 y 50 kg de P2O5/ha y de la inoculacion en la fijacion biologica de N en 3 var. de frijol (Nasaka, P402 y 13-3), la nodulacion efectiva fue superior cuando se aplicaron 50 kg de P2O5/ha y se inoculo con Rhizobium MG 366. La aplicacion de P a semilla inoculada puede incrementar significativamente la nodulacion y por consiguiente, la tasa de fijacion de N. No hubo diferencias significativas de los rendimientos de semilla entre tratamientos; sin embargo, la aplicacion de P incremento los rendimientos prom. de semilla. La mejor respuesta a la inoculacion se obtuvo con P402 (1200 kg/ha de semilla con la dosis de 25 kg de P2O5).
