Resumo: The purpose of the present research was to study the effects of different water management during the sowing, in pre-germinated system, on the establishment of two rice cultivars and the effects on yield components and rice grains production. The experiment was conducted in amianthus cement boxes of 500 liters of capacity with alluvial soil with two rice cultivars (IAC 102 e Epagri 108) and three water managements (1 - sowing in water and maintenance of constant water level; 2 - sowing in water and water retreat after three days; 3 - sowing in water and natural evaporation). Taking out water from the field, three days after sowing also resulted in a better seedling establishment. Water level management by natural evaporation resulted in the highest number of total spikelets per panicle. The grain yield was not affected by water management. Yield of IAC 102 presented higher number of plump spikelets per panicle, relating to greater grain yield

Os tratamentos foram duas cultivares de arroz irrigado (IAC 102 e Epagri 108) e três manejos da lâmina de água (1- semeadura em lâmina de água e manutenção constante dessa; 2 - semeadura em lâmina de água e retirada da água após três dias; 3 - semeadura em lâmina de água e evaporação natural da água). O manejo da lâmina de água com retirada três dias após a semeadura proporcionou melhor estande de plantas. O manejo da lâmina de água com evaporação natural proporcionou maior número total de espiguetas por panícula. A produtividade de grãos não foi afetada pelo manejo de água. A cultivar IAC 102 apresentou maior número de espiguetas granadas em relação à Epagri 108, refletindo na produtividade de grãosUniversidade Estadual de Maringá2008-04-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/239110.4025/actasciagron.v24i0.2391Acta Scientiarum.
