Selection of rice genotypes (Oryza sativa) with high nitrogen agronomic efficiency in an Acuic Durixererts soil, central-southern Chile. 40(2): 375-385. Nitrogen agronomic efficiency (NAE) is a key factor that has not been considered in rice breeding programs. The objective of this study was to evaluate nitrogen agronomic efficiency in twenty rice genotypes in an Acuic Durixererts soil (Quella Series) located in Chile's south central zone (36°04'S, 72° 0'W) over the 2008-09 growing season. The field experiment was carried out in a complete randomized split-plot block design with five N treatments of 0, 50, 100, 150 and 200 kg ha-1 and twenty genotype sub-treatments. The... |

| ABSTRACT Rice (Oryza spp.), the most important cereal in the world, is grown and consumed in all continents. Brazil is among the top ten producing countries. Stored grains can be attacked by pests (rodents, insects, fungi and mites) that cause serious qualitative and quantitative losses. Because of these losses, one way to alleviate the problem caused by insects during rice storage is the use of resistant materials (grains). Thus, the aim of this study was to evaluate grains from nine different genotypes of rice, in order to identify the existence of materials less susceptible to the attack of Sitophilus zeamais, during 180 days of storage. The mean time of biological cycle (days), susceptibility index (IS) and the number of weevils emerged were evaluated.... |
