| En Noreste de Brazíl, existe una gran variabilidad de factores de orden físico, biológico y socío-economíco, los cual es han contribuído para dísmínuír el desarrollo agrícola y ganadero de Ia regíón. Por otra parte, el agricultor tradicional a nível de subs ístencia, rechaza fuertemente Ias nuevas tecnologtas, fundamentalmente por no entender claramente Ia justificación de una determinada práctíca, ya que Ias tecnologías modernas no harrconstderado sus condícíones socia.les y economícas. Sin embargo, el "Centro de Pesquisa Agropecuaría do Trópico Semi-Ar ído'' (CPATSA/EMBRAPA), en Petrolina, PE., Brazíl , considera conveniente Ia conjugacíón de Ia tecnologta moderna con Ios sistemas tradícíonales, a través de un equipo interdisciplinario e inter... |

| ABSTRACT The study of cultivars with moderate flood tolerance is essential to their use in pastures irrigated with saline water. The aim of this study was to evaluate the chemical composition of Panicum maximum ‘BRS Zuri’ under the effect of different irrigation depths and levels of salinity. A randomised block design of split plots was used with five replications per treatment. The treatments resulted from the combination of three levels of water salinity (S1 = 0.6, S2 = 1.8 and S3 = 3.0 dS m-1) and four levels of irrigation (I1 = 60%, I2 = 80%, I3 = 100% and I4 = 120% of the evapotranspiration). The chemical composition of the grass, Panicum maximum ‘BRS Zuri’, cut at 28 days, was evaluated over two cycles. There was an interaction between the factors... |

| ABSTRACT This research was conducted in order to evaluate the growth and production of colored-fiber cotton, cv. ‘BRS Rubi’, irrigated with water of different salinities and nitrogen (N) doses. The experiment was carried out in drainage lysimeters filled with soil material from an eutrophic Regolithic Neosol with sandy-loam texture under greenhouse conditions in Campina Grande, PB. The experiment was conducted in a randomized block design and the treatments consisted of five levels of irrigation water salinity with the following electrical conductivities - ECw (5.1, 6.1, 7.1, 8.1 and 9.1 dS m-1), combined with five N doses - ND (65; 100; 135; 170; 205 mg of N kg-1 of soil), distributed in a 5 x 5 factorial scheme with three replicates. The growth of the... |

| ABSTRACT The split-root technique was used as a strategy to reduce saline stress on pepper. A completely randomized design with six treatments and four replicates was used. The treatments consisted of six saline water application strategies (T1 - salinized nutrient solution (S1 = 1.4 dS m-1) during the whole cycle; T2 - salinized nutrient solution (S2 = 4.5 dS m-1) throughout the cycle, T3 - S1 and S2 throughout the cycle, using two emitters and without splitting the root system, T4 - S1 and S2, using two emitters and splitting the root system by a plastic film, T5 - S1 and S2, using two emitters and splitting the root system, alternating the solutions every 15 days, T6 - S1 and S2, using two emitters and without splitting the root system, alternating the... |

| The effects of NaCl salinity on seed germination, growth, physiology, and biochemistry of two bambara groundnut landraces (Vigna subterranea (L.) Verdc), Kakamega (white seed coat) and Mumias (red seed coat), were investigated with the aim of establishing traits, which can provide a basis for breeding to salt tolerance in groundnuts. A study was conducted under laboratorial and greenhouse conditions. Bambara groundnut seeds and plants were subjected to five concentrations of NaCl solutions with several electrical conductivities: 0 (control), 6.96, 12.93, 19.89, and 25.86 dS m-1. Germination percentage, growth, chlorophyll fluorescence, and leaf chlorophyll content were determined. Sodium chloride salinity (p<0.05) significantly decreased germination and... |

| Mais de 16.000 pocos ja foram perfurados nas rochas igneas metamorficas do embasamento cristalino do Semi-Arido do Nordeste do Brasil, segundo levantamento de 1983. Os aquiferos nestas formacoes sao constituidos por fraturas e fendas da rocha, cujas caracteristicas hidrogeologicas se desconhecem. Caracteristicas de vazoes esses pocos e qualidade das aguas tem marginalizado a utilizacao racional desse recurso. Assim, tem-se vazoes que variam entre 0,0 a mais de 16.000 l/h e pode-se dizer que, em geral, as aguas sao mineralizadas em maior ou menor grau, com teores de residuo seco variando entre 1 a 10 g/l. O objetivo deste trabalho e, pois, apresentar as alternativas e possibilidades de uso destas aguas subterraneas do embasamento cristalino na regiao, ainda... |

| PIRATA (Brazil, France, USA) has deployed between 1997 and 2001, an array of 12 ATLAS buoys with the objective of monitoring, describing and understanding the evolution of sea surface temperature, upper ocean thermal and saline structure, net heat budget, air-sea fluxes of momentum, latent and sensible heat and fresh water in the tropical Atlantic. The oceanic and meteorological observations are transmitted to shore via satellite and are available in near real-time on the Internet. They are communicated to the Global Telecommunication System and readily available for ocean and weather prediction models. The ultimate objective of PIRATA is real-time ocean monitoring to enable resource prediction in the adjacent countries. |

| Le branchiopode Artemia représente le principal organisme vivant colonisant les biotopes hypersalés. L’étude taxonomique de l’Artemia au niveau de la région ouest méditerranéenne, incluant l’Italie, la France, l’Espagne, le Portugal et le Maroc, a révélé la présence de l’espèce Artemia franciscana (qui a pour origine le continent Américain) comme étant une espèce invasive. Dans ce travail, une nouvelle population d’Artemia a été rapportée pour la première fois au niveau de Sabkhet Halk El Manzel. Une première identification taxonomique de cette population a été réalisée moyennant une étude morphologique et comparative de la forme de l’ovisac des femelles avec cinq autres populations tunisiennes appartenant à l’espèce Artemia salina et avec l’espèce... |
