Foi estudada, em condições de sequeiro, a associação das características morfológicas de plantas de cultivares e linhagens de arroz com o nível de dano causado por Diatraea saccharalis. A percentagem de colmos atacados pela broca foi diretamente correlacionado com a altura das plantas, com o número e comprimento dos internódios e com os diâmetros interno e externo dos colmos; ao contrário, foi negativamente correlacionada com o grau de perfilhamento das plantas. Ocorreu uma tendência de cultivares e linhagens com folhas pilosas serem menos danificadas. Entre os germoplasmas estudados, as cultivares de arroz consideradas de sequeiro apresentaram a maioria das características morfológicas associadas com a suscetibilidade à broca-do-colmo e foram mais danificadas que os materiais genéticos introduzidos. |

This study analyzes the relation between Brazilian broiler and pig production and water productivity using recently developed reference guidelines on water footprinting for livestock production systems and supply chains. Dierent rainfed crop arrangements, in dierent scenarios and producer regions in Brazil, were assessed. Water productivity of broiler feed consumption ranged from 0.63 to 1.38 kg perm3 water input to rainfed summer maize (safra) and from 1.20 to 2.21 kg perm3 water input to winter maize (safrinha) while it ranged from 0.28 to 0.95 kg perm3 water input to rainfed soy. For pig feed consumption, rainfed maize ranged from 0.68 to 1.49 kg per m3 water input (safra) and from 1.30 to 2.38 kg perm3 water input (safrinha) while it ranged from 0.30 to 1.03 kg per m3 water input to rainfed soy. A potential amount of water saving of 0.0336 km3 year-1 and 0.0202 km3 year-1 could be attained for producing broiler and pig feed, respectively, depending on the crop rotation and producer region. The results showed that the evapotranspiration of animal feed production represents more than 99% of the total water consumption for broiler and pig production in the study area. The implementation of best crop practices resulted in higher water productivity values of chicken and pork meat and also improved the rainfall water-saving in comparison to conventional agriculture. Hence, the water productivity of the animal production chain in tropical regions demands a close relation to agriculture in order to attain a better understanding and improvement of rainfall water productivity for animal feed production.
