EVALUACIÓN DE DAÑO POR AVES EN CULTIVARES DE SORGO (SORGHUM BICOLOR) EN LAS BREÑAS, PROVINCIA DEL CHACO.

Abstract

Experiments were conducted in 2013 (A) and 2014 (B) in Las Breñas (27º 05` S - 61º 06` O, 101.6 m snm) to estimate yield losses caused by birds in microparcelas with different varieties of sorghum. In 2013 greater damage by birds was registered compared to 2014. In both years damage by birds was more relevant in sorghum varieties without tannin. In the present study the greater permanence of the materials in the field would influence the grain losses caused by birds, which was reflected in major losses in the short course materials regarding intermediate cycle-intermediate long and spent less time longer than grain in the field as the hybrid crop longest performed in a single operation when mature
