| The practices and techniques used in irrigated rice to improve performance include optimal plant density and the best arrangement of the plants in an area. This study aims to evaluate the performance and plasticity in the yield and grain quality of three rice hybrids using different row spacing. The field experiments were conducted during the 2010/2011 season in rice crops in Capão do Leão, Viamão and Uruguaiana in the state of Rio Grande do Sul, Brazil. Three different sowing arrangements were evaluated, i.e., row spacing of 17 cm, 34 cm, and 17 cm alternated with 34 cm, which corresponded to densities of 40, 20 and 32 kg ha-1, respectively. The experimental design used was randomized blocks with subdivided plots replicated three times considering each... |
