Embrapa Arroz e Feijão [email protected] Presentation Changes in the composition of cultivated areas are determined by several factors. Undoubtedly, financial profitability and access to the marketplace are important factors in the process. In Mato Grosso do Sul, more than 95% of rice production comes from crops on irrigated lowlands. Their yield is relatively high, 5,681 kg ha-1, but still about a ton below the national average, which is strongly influenced by the performance of Rio Grande do Sul, where productivity has already exceeded seven tons per hectare. The search for high yields through good agricultural practices is the best strategy when natural resources, especially soil, water and light are used. Profitability improvement for irrigated rice in Mato Grosso depends largely on production systems which are appropriate to local conditions and on additional efforts throughout the chain of production. The need to increase rice production in the State of Mato Grosso do Sul, in a sustainable and competitive way, integrating and invigorating the entire chain of production was the reason Embrapa’s research team wrote this paper. It discusses several technologies specifically aimed at increasing the competitiveness of the irrigated rice crop production in Mato Grosso do Sul.

Anomochlooideae are endemic to the New World and have two tribes and two genera in- cluding the widespread Streptochaeteae (3–4 spp.) and the critically endangered Anomochloeae (1 sp.) of coastal Bahia, Brazil. Pharoideae are pantropical with one tribe, three genera, and 14 species; all eight species of Pharus occur only in the New World. Bambusoideae and Ehrhartoideae are sister groups and together form a clade sister to Pooideae, although support for this set of relationships is low.

Abstract Richness (alpha and beta diversity), abundance and dominance of bioforms of aquatic vegetation in a wetland of the Orinoco floodplains in Venezuela, studied over an annual cycle are described. In a lowland extension of 65,000 hectares including a whole range of aquatic habitats (shallows, marshes, ponds and streams), 197 species belonging to 122 genera and 56 families were recorded. Beta diversity was higher in lentic than in lotic wetlands, the emergent rooted bioform being the most abundant in all habitats and throughout the year. Considering the most persistent species (spatially and temporally), Eichhornia crassipes (Mart) Solms., Hymenachne amplexicaulis (Rudge) Nees and Luziola subintegra Swallen obtained the highest relative importance values.

Therefore, our objectives were to identify and quantify the aquatic macrophytes of North Brazilian states, analyzing herbaria data plataforms (SpeciesLink and Flora do Brasil). The checklist was produced by bibliographic search (articles published between 1980 and 2000), herbaria collections of the platforms SpeciesLink and Flora do Brasil and field expeditions, where we utilized asystematic sampling. We also analyzed the floristic similarity of aquatic macrophytes among Northern Brazil, wetlands of distinct Brazilian regions and the Neotropics. We recorded 539 species, of which 48 are endemic to Brazil.
