C. Quezada, S. Hernaíz, I. Vidal, R. Alvarado, R. Gallegos, and W. Yañez. 2013. 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... |
