Abstract

Field studies were conducted in 2011 and 2012 at the Sandhills Research Station near Jackson Springs, NC to determine the influence of weed-free strip width (WFSW) on newly planted ‘Navaho' blackberry plant growth, fruit yield, and fruit quality. Treatments consisted of 0-, 0.3-, 0.6-, 1.2-, 1.8-, and 2.4-m WFSW. Predicted blackberry yield increased from 718 to 1,015 kg ha−1 at WFSW of 0 to 2.4 m. The currently recommended WFSW of 1.2 m resulted in a blackberry yield of 1,013 kg ha−1. Predicted individual blackberry fruit weight displayed a positive linear response to WFSW and increased from 3.1 to 3.6 g fruit−1 at WFSW of 0 to 2.4 m. Soluble solids content (SSC) of dull black blackberry fruit was greatest (15.1 Brix) when WFSW was 0 m. Relative to a WFSW of 0 m, SSC was reduced 2.3 to 3.4% as WFSW increased from 0.3 to 2.4 m, respectively. WFSW did not influence shiny black blackberry fruit SSC, nor titratable acidity, sugar-to-acid ratio, or pH of shiny or dull black blackberry fruit or primocane number, length, and stem caliper.

En 2011 y 2012, se realizaron estudios de campo en la Estación Experimental Sandhills, cerca de Jackson Springs, NC, para determinar la influencia del ancho de banda libre de malezas (WFSW) en el crecimiento, rendimiento y calidad de fruta de plantaciones nuevas de mora 'Navaho'. Los tratamientos consistieron de WFSW de 0, 0.3, 0.6, 1.2, y 2.4 m. El rendimiento predicho de la mora aumentó de 718 a 1,015 kg ha−1 al aumentar WDSW de 0 a 2.4 m. El WFSW actualmente recomendado, el cual es 1.2 m, resultó en un rendimiento de 1,013 kg ha−1. El peso individual predicho del fruto mostró una respuesta lineal positiva al WFSW e incrementó de 3.1 a 3.6 g fruto−1 al incrementar WFSW de 0 a 2.4 m. El contenido de sólidos solubles (SSC) de los frutos de mora mate fue mayor (15.1 Brix) cuando WFSW fue 0 m. En relación a WFSW de 0 m, SSC se redujo de 2.3 a 3.4% al incrementarse el WFSW de 0.3 a 2.4 m, respectivamente. WFSW no influenció el SSC de frutos de mora brillantes, ni la acidez titulable, el ratio azúcar-ácido, o el pH de frutos brillantes o mate de mora ni el número, largo y calibre del tallo vegetativo.
