In: In: Congresso Brasileiro de Mandioca (1, 1979, Cruz das Almas, Brasil). AnaisSummary: Se realizo una serie de 8 expt. en las areas productoras de yuca del Estado de Bahia (Brasil) para determinar el efecto de aplicacion de NPK a 3 dosis diferentes (0, 60 y 120 kg/ha) en la produccion de raices de yuca. Se utilizo un diseno factorial 3 x 3 x 3. Ademas, se realizaron expt. sobre el efecto de las aplicaciones de cal, S y micronutrimentos (Zn, Cu, B y Mo) utilizando un diseno de bloques al azar con 3 repeticiones. El rendimiento se incremento significativamente con P; sin embargo, la fertilizacion con N y K demostro poco efecto en el rendimiento. Se observo una respuesta significativa a N solamente en un sitio, mientras que la respuesta a K fue significativa en 2 expt. Las aplicaciones de cal y micronutrimentos no presentaron efectos marcados en la productividad. (RA-CIAT)Summary: A series of 8 expt. was carried out in cassava-growing areas of the state of Bahia (Brazil) in order to determine the effects of 3 different rates (0, 60, and 120 kg/ha) each of N, P, K application on cassava root production. A 3 x 3 x 3 factorial design was used. Additional expt. on the effect of lime, S, and micronutrients (Zn, Cu, B, and Mo) were also conducted using a randomized block design with 3 replications. Results show that yield significantly increased with P fertilization; however, N and K fertilization showed little influence on yield. At only 1 site a significant response to N was observed while K responses were significant in 2 expt. Liming and micronutrient application did not show marked effects on productivity. (AS)
