Resumo: | With the objective of evaluate the effects of water levels and mineral fertilizers on the mill revenue and nutrient content ot the grains of upland rice cv. IAC 201, two experiments were conducted in Selvíria, state of Mato Grosso do Sul, Brazil. The experimental design was randomized blocks and treatments consisted of five water levels: natural rain and four water levels supplied by sprinkler irrigation. Irrigation levels were based on crop coefficient (Kc) for dryland rice that resulted in water level 2 (L2). Water levels L1 and L3 were then defined as 0.5 and 1.5 Kcs used in L2, respectively, and on water level 4 (L4) was used Kc=1,95, during all plant cicle. In 1995/96 the same treatments were applied in a split-plot scheme, where subplots consisted of two NPK-fertilization levels (300 e 600kg ha-1 of formula 04-30-10). Sprinkler irrigation incresed hulling yield, and undamaged grains; low water availability incresed P, Ca, Mg, and Fe and, decreased K and S content of polished grains; the mineral fertilizer levels did not interfere in the nutrients and protein content of polished grains and industrial quality of grains, in soil with appropriete nutrients levels. |

IAC 201, obtidos em experimentos de campo com diferentes lâminas de água e níveis de adubação mineral, nos anos agrícolas de 1994/95 e 1995/96, em Selvíria, Estado do Mato Grosso do Sul, Brasil. O delineamento experimental foi por blocos casualizados, com quatro repetições. Os tratamentos constituíram-se da precipitação pluvial natural e de quatro lâminas de água fornecidas por aspersão. A lâmina L2 foi baseada no coeficiente de cultura (Kc) do arroz de terras altas. As lâminas L1 e L3 foram definidas como 0,5 e 1,5 vez os Kcs utilizados em L2, respectivamente, e na lâmina L4 foi adotado Kc=1,95 durante todo o ciclo da cultura. Em 1995/96, utilizaram-se os mesmos tratamentos em parcelas subdivididas, sendo as subparcelas constituídas por dois níveis de adubação NPK (300 e 600kg ha-1 da fórmula 04- 30-10). O rendimento de benefício e de grãos inteiros do cultivar IAC 201 foi incrementado com a utilização da irrigação por aspersão. A menor disponibilidade de água proporcionou aumento nos teores de P, Ca, Mg e Fe e redução nos de K e S nos grãos brunidos decorrentes de efeito de diluição/concentração em função da produtividade de grãos. Os teores de nutrientes e de proteínas nos grãos brunidos e a qualidade industrial dos mesmos não foram afetados pelo aumento da adubação mineral em solo com teores adequados de nutrientes.
