Resumo: The objective of this work was to study the influence of different seeding rates and cultivars over flooded rice yield at the west border of Rio Grande do Sul State. The experimental design was a randomized blocks with four replicates. The treatments were arranged in factorial scheme 4 x 3, in which factor A was the seeding rate (40, 60, 80 and 100kg ha-1) and B the cultivars (BR-IRGA 409, Olimar and Puitá Inta-CL). The increase in seeding rate from 40 to 100 kg ha-1 reduces linearly the tilled number, filled, total grains for panicle and number of panicle per m2. The greater rice grains yield in cultivars Olimar and Puitá Inta-CL is obtained in seeding rate of 66 and 77 kg ha-1 respectively. On the other hand, the yield of cultivar BR-IRGA 409 was not influenced by seeding rate. The yield grain was greater in cultivar Puitá Inta-CL, except with the seeding rate of 80 kg ha-1, in which it was the second most productive cultivar.

O delineamento experimental foi em blocos causalizados, com quatro repetições. Os tratamentos foram arranjados em esquema fatorial 4 x 3, onde o Fator A foi composto pelas densidades de semeadura (40, 60, 80 e 100 kg ha-1) e o B pelas cultivares (BR-IRGA 409, Olimar e Puitá Inta-CL). O aumento na densidade de semeadura de 40 a 100 kg ha-1 reduz linearmente o número de perfilhos por planta, o número de grãos cheios e total por panícula e o número de panículas por m2. A maior produtividade de grãos de arroz para a cultivar Olimar e Puitá Inta-CL é obtida na densidade de semeadura de 77 e 66 kg ha-1 , respectivamente, e a produtividade da cultivar BR-IRGA 409 não é influenciada pela densidade de semeadura. A produtividade de grãos é superior na cultivar Puitá Inta-CL, exceto na densidade de semeadura de 80 kg ha-1, em que esta é a segunda cultivar mais produtiva.Departamento de Diagnóstico e Pesquisa Agropecuária.
