1. Patterns recognition methods to study genotypic similarity in flood-irrigated rice
ABSTRACT Genetic diversity studies are performed based on information on a set of traits measured in a group of genotypes, considering one or more environments. The pattern recognition methods allow classifying genotypes from a set of important agronomic information. Thus, this study aimed to present and compare pattern recognition methods to inquire about t

4. Greenhouse gas emission, water quality and straw decomposition as a function of rice postharvest field management
ABSTRACT The objective of this paper was to evaluate the quality of water drained after the use of the knife-roller (an implement used to incorporate rice residues after harvest), the partial global warming potential (pGWP) and straw decomposition as a result of postharvest field management of irrigated rice. The experiments were conducted during the 2018 an

6. Quantitative and qualitative damages of Oebalus poecilus on irrigated rice in southern Brazil
ABSTRACT Oebalus poecilus is one of the most important pests of irrigated rice in Brazil. However, the impact of this species on the cultivar IRGA 424 RI, which is the most used, is unknown. Hence, the objective of this work is to evaluate the damage caused by O. poecilus on cv IRGA 424 RI. Panicles of this cultivar were infested for seven days at the R5 sta

7. BRS 901 and BRS 902: red rice cultivars bred for Brazil
Abstract BRS 901 and BRS 902 are red pericarp rice cultivars developed by Embrapa for irrigated and rainfed lowland production systems in Brazil. These cultivars have medium and early maturation cycles, respectively, and both have high grain yield potential, good lodging tolerance and short to medium length grains.

8. Introducing rice yield loss caused by weed competition into the SimulArroz model
Resumo: O objetivo deste trabalho foi modelar a competição de arroz-daninho (Oryza sativa) e capim-arroz (Echinochloa spp.) com o arroz irrigado por inundação e introduzi-la como um submodelo no modelo SimulArroz. A competição das duas ervas daninhas com o arroz irrigado foi modelada com o uso da equação da hipérbole retangular. Os coeficientes “i

9. Nitrogen sufficiency index for estimating nitrogen fertilizer requirement of irrigated rice
ABSTRACT The proper nitrogen management is required to achieve high irrigated rice yield. This study aimed to determine the rice response to nitrogen topdressing doses and calibrate the chlorophyll meter reading. Three experiments were conducted in a randomized block design. In the first experiment, five N rates (0, 30, 60, 90, and 120 kg ha-1) were evaluat

10. Saline-sodic soil treated with gypsum, organic sources and leaching for successive cultivation of sunflower and rice
RESUMO A correção de solos salinos e sódicos objetiva reduzir os sais dissolvidos na solução e sódio trocável, respectivamente, possibilitando o crescimento e a produção das culturas. Neste contexto, um experimento foi desenvolvido, entre agosto/2011 e setembro/2012, em solo salino-sódico do Perímetro Irrigado de São Gonçalo, no município de So

11. Goosegrass: Morphophysiological Characterization Under Water Excess Conditions
RESUMO: A espécie Eleusine indica (L.) Gaertn. (capim-pé-de-galinha) é uma gramínea que possui destaque global como infestante em áreas típicas de cultivos agrícolas da soja. Entretanto, nos últimos anos sua dispersão vem sendo relatada expressivamente para áreas de solo mal drenado, em que é cultivado arroz irrigado (terras baixas). Nesse diferen

12. Morphological and Phenological Responses of Eragrostis plana Nees and Eragrostis pilosa (L.) P. Beauv. Plants Subjected to Different Soil Moisture Conditions
RESUMO: Realizou-se um experimento em casa de vegetação onde submeteu-se acessos de Eragrostis pilosa e Eragrostis plana, espécies infestantes da cultura do arroz, a três condições de umidade do solo (50% da Capacidade de retenção de água do solo (CRA), 100% da CRA, lâmina de água de 10 cm) simulando três ambientes diferentes (ambiente de terras
