Se informa de los resultados de 3 cultivos consecutivos para estudiar las respuestas al K y Mg de 2 cv. mejorados de yuca, TMS 30395 y 30211, cultivados en un Ultisol (Typic paleudult), franco arenoso, acido, en el sur de Nigeria. En tierra recientemente rozada del barbecho de Eupatorium, se observo una respuesta signficativa al K en el primer ano del cultivo para el cv. TMS 30395 de crecimiento mas vigoroso. Ambos cv. respondieron a la aplicacion de K en tasas de 30 y 60 kg/ha en el segundo y tercer cultivos, resp. Una respuesta significativa a la aplicacion de 20 kg de Mg/ha fue observada para el cv. TMS 30211 en el tercer cultivo. El cv. TMS 30395 parece ser mas efectivo en la utilizacion del Mg del suelo. (RA-CIAT)
Results of 3 consecutive croppings to study the K and Mg responses of 2 improved cassava cv., TMS 30395 and 30211, grown on an acid, sandy loam, Ultisol (Typic paleudult) in southern Nigeria are reported. On land newly cleared from Eupatorium fallow a significant K response in the 1st cropping year was observed only with the more vigorous cv. TMS 30395. Both cv. responded to K applications at rates of 30 and 60 kg/ha in 2nd and 3rd croppings, resp. A significant response to application of 20 kg mg/ha was observed in the 3rd crop with cv. TMS 30211. cv. TMS 30395 seems to be more effective in utilizing Mg from the soil. (AS)
