Digital, genetic and molecular breakthroughs are pushing forward the frontiers of how people can use technology to eradicate poverty. These breakthroughs are creating new possibilities for improving health and nutrition, expanding knowledge, protecting natural resources, stimulating economic growth and empowering people to participate in their communities. Information and communication technology (ICT) can be a powerful enabler of development goals because of its unique characteristics that dramatically improve communication and the exchange of information. ICT fosters the dissemination of information and knowledge by separating content from its physicallocation. This flow of information is largely unobstructed by geographic boundaries-allowing researcher to become integrated into global networks and making information accessible. ICARDA s Arabian Peninsula Regional Program (APRP) in collaboration with National Agricultural Research Institutions in Bahrain, United Arab Emirates, Saudi Arabia, Oman, Qatar, Kuwait and Yemen has developed Information Technology Systems for Agriculture and Natural Resources Management in the Arabian Peninsula (IT AP). An Internet-based expert system for cucumber under protected agriculture has been developed in collaboration with the Central Laboratory for Agricultural Expert Systems (CLAES), Cairo, Egypt. The Expert Systems (ES) are a computer program designed to combine the experimental knowledge and experience with the intuitive reasoning skills of a multitude of specialists to aid growers, extension personnel and researchers in making the best decisions for their crops. The ES was up-loaded on the Internet and made available in Arabic under www.icarda.cgiar.orglaprp/it.htm. The Weather Stations Network for the Arabian Peninsula has also been established. Eleven automatic weather stations were installed in the AP countries at pre-specified locations and connected through telephone lines and linked to ICARDA-APRP Internet website to make data available for the estimation of near real-time crop water requirement and irrigation management. Also, an irrigation and fertigation management programe for green house crops was developed and made avaliable in Arabic on ICARDA/APRP site. This was developed in collaboration with the Central Laboratory for Agricultural Climate (CLAC), Cairo, Egypt MenosDigital, genetic and molecular breakthroughs are pushing forward the frontiers of how people can use technology to eradicate poverty.

Resumo: Experimento conduzido na Embrapa, em Barbalha, CE, nos anos de 2003 e 2005, objetivou a estimativa da evapotranspiração da cultura e do coeficiente de cultivo do algodoeiro BRS-200 Marrom. Sensores de radiação solar global; saldo de radiação; temperatura do ar (bulbos seco e úmido) e velocidade do vento nos níveis de 0,30 e 1,50 m acima da copa da cultura e fluxo de calor no solo foram instalados e os dados coletados por um sistema automático de aquisição de dados. A evapotranspiração da cultura (ETc) e a evapotranspiração de referência (ETo) foram estimadas pelos métodos da razão de Bowen e Penmam-Monteith, respectivamente, enquanto o coeficiente de cultivo (Kc) foi determinado pela razão ETc/ETo. A ETc da cultura variou em função de sua fenologia, obtendo-se valores médios de 3,8 mm d-1 no período da emergência a 10% da cobertura de solo (Fase I); 5,0 mm d-1 no período do crescimento vegetativo (Fase II); 5,9 mm d-1 no período do desenvolvimento reprodutivo (Fase III) e 5,4 mm d-1 no período de maturação (Fase IV). O Kc pode ser definido em função dos dias após a emergência, pela equação Kc = -0,00006 DAE2 + 0,009 DAE + 0,632. Abstract: Field experiments were carried out at the EMBRAPA, Barbalha, CE, during the growing seasons of 2003 and 2005 with the objective of estimating the evapotranspiration and crop coefficient of irrigated BRS-200 Marrom cotton cultivar. For this sensors of solar radiation, net radiation, dry and wet bulbs air temperature and wind speed at the 0.30 and 1.50 m levels above crop canopy and soil heat flux were installed and data were collected by a data acquisition system. Crop (ETc) and reference (ETo) evapotranspiration were estimated by the Bowen ratio and Penman-Monteith methods, respectively, while the crop coefficient (Kc) was estimated by the ratio of ETc to ETo. The ETc changed throughout the phonological cycle of the cotton crop, with mean values of 3.8 mm d-1 in the period from emergence to 10% of soil cover (phase I), 5.0 mm d-1 in the period of vegetative growth (phase II), 5.9 mm d-1 in the period of reproductive development (phase III) and 5.4 mm d-1 in the maturation period (phase IV). The Kc may be estimated as a function of the days after emergence (DAE) as: Kc = -0.00006 DAE2 + 0.009 DAE + 0.632.
