The purpose of the research was to study the use of liming, seeding density of two paddy rice cultivars and harvest time with rice yield and mill quality. The experiment was carried out during 1993/94 growing season in Casemiro de Abreu (RJ), Brazil. The two rice cultivars used were BR-IRGA 409 and BR-IRGA 412, two of limestone doses (0 and 200kg ha-1) and three seeding densities (100, 200 and 300kg ha-1) were distributed in a completely randomized block design. The use of liming and variation of seeding density did not affect rice quality. The moisture content of the rice grains that resulted in highest quality at harvest was between 17,5-22%.
