 In: Boletim da Secretaria de Agricultura, Industria e Comercio (Brazil)Summary: Se realizaron pruebas con 27 tratamientos de bloques al azar en Tambe (Pernambuco, Brasil) para determinar las distancias optimas de siembra. Las variaciones estudiadas entre los surcos oscilaron de 0.60 a 1.60 m; la diferencia entre plantas fue de 0.10 a 0.30 m menor que la distancia entre surcos. A los 18 meses, la produccion vario entre 10,402 (1.40 x 1.30 m) y 20,555 kg/ha (0.60 x 0.30 m), produciendo 2.24 y 0.642 kg/planta resp. Despues de hacer calculos de estas estacas/ha, se decidio realizar una tercera prueba (1.20 x 1.50 m) con menos estacas/ha, lo que permitio la desyerba mecanizada hasta los 3 meses. El mayor porcentaje de almidon se obtuvo con este tratamiento. Las distancias de siembra no afectaron notablemente la formacion de almidones segun las muestras analizadas. (CIAT)Summary: Trials using 27 randomized block treatments were conducted in Tambe, state of Pernambuco (Brazil) to determine optimum planting distances. Variations studied between rows ranged from 0.60-1.60 m; the difference between plants was from 0.10-0.30 m less than the distance between rows. At 18 mo, the production ranged between 10,402 kg/ha (1.40 m x 1.30 m) and 20,555 kg/ha (0.60 m x 0.30 m), yielding 2.24 and 0.642 kg/plant respectively. After calculations were made of these stakes/ha, it was decided to conduct a 3rd trial (1.20 m x 1.50 m), using fewer stakes/ha, which permitted mechanized weeding up to 3 mo. The highest percentage of starch was obtained in this treatment. Planting distances did not noticeably affect starch formation according to samples analyzed. (CIAT)
