Abstract

Field studies were conducted in 2013 at Houlka, MS and 2014 at Houston and Pontotoc, MS to determine the influence of yellow nutsedge density on 'Beauregard' sweet potato yield and quality. Treatments established 2 wk after transplanting (WAP) were yellow nutsedge densities of 0, 5, 10, 15, 30, 40, 50, and 90 shoots m−2 within the planted row. No. 1 and marketable yield loss were fit to a rectangular hyperbola model. In 2013 predicted yield loss of no. 1 and marketable grades ranged from 23 to 96% and 18 to 80%, respectively for yellow nutsedge densities of 5 to 90 shoots m−2. In 2014 predicted yield loss of no. 1 and marketable grades ranged from 7 to 74% and 6 to 67%, respectively for yellow nutsedge densities of 5 to 90 shoots m−2. Yellow nutsedge shoot density increased linearly from 2 WAP to harvest. At Houston and Pontotoc, yellow nutsedge shoot density increased 2.3 and 7.6 times, respectively, for every one shoot present at 2 WAP.

Estudios de campo fueron realizados en Houlka, Mississippi en 2013, y en Houston y Pontotoc, Mississippi en 2014, para determinar la influencia de la densidad de Cyperus esculentus sobre el rendimiento y calidad de la batata ‘Beauregard’. Los tratamientos establecidos 2 semanas después del trasplante (WAP) fueron densidades de C. esculentus de 0, 5, 10, 15, 30, 40, 50, y 90 plantas m−2 en la línea de siembra. La pérdida de rendimiento comercializable y no. 1 fue descrita con un modelo hiperbólico rectangular. En 2013 la pérdida de rendimiento predicha de los grados no. 1 y comercializable varió de 23 a 96% y 18 a 80%, respectivamente para las densidades de C. esculentus de 5 a 90 plantas m−2. En 2014 la pérdida de rendimiento predicha de los grados no. 1 y comercializable varió de 7 a 74% y 6 a 67%, respectivamente para las densidades de C. esculentus de 5 a 90 plantas m−2. La densidad de plantas de C. rotundas aumentó linealmente desde 2 WAP hasta la cosecha. En Houston y Pontotoc, la densidad de plantas de C. esculentus aumentó 2.3 y 7.6 veces, respectivamente, para cada una de las plantas presentes a 2 WAP.
