Avaliação do desempenho industrial de cinco cultivares de arroz irrigado (Oryza sativa)

Abstract

Rice cultivation is the main agricultural activities in Brazil, especially in the Western Border of Rio Grande do Sul The industrial quality of grain is an important parameter to determine the commercial value of rice and can be related to water availability and cultivate used. Therefore this paper aims to analyze the milling yield and the incidence of defects and features five cooking rice cultivars-IRGA 409, IRGA-417-IRGA 424, IRGA-427 and CL-puíta INTA, these cultivars that are the most seeded Border West of Rio Grande do Sul, in the system of flood irrigation. The tests were performed at the Federal University of Pampa, Itaqui campus, as well as company Camil Alimentos S / A, also located in the same municipality. The evaluations showed that the IRGA409, has a better yield of grain, a larger amount of grains with 3/4 of the normal size, ie almost perfect grain, lower incidence of defects in training and still has the lowest cooking time with optimal absorption of water during growth which increases the volume of the grain.
