“…Ces différentes pertes s'observent lors des inondations des champs par les eaux de pluies d'une part et part les eaux des crue (Zoundjè et al, 2000). Dans de nombreux pays en Afrique subsaharienne, les agriculteurs manquent généralement des moyens adéquats et des incitations sur les besoins en eau des cultures, les différentes technologies d'irrigation, les différentes effets des diverses technologies sur les rendements des cultures (Levidow et al, 2014). L'absence d'un cadre politique favorable à l'irrigation constitue aussi un obstacle majeur au Bénin.…”

Water management for agriculture is a worry in the world. The objective of this study is to provide an overview of the current knowledge on water control's technologies for the crops in wetlands. Comparison research work carried out on different irrigation systems revealed that drip irrigation can lead to 28-35% of water saving in relation to irrigation surface technic. Surface irrigation offers higher yield in relation to drip irrigation. It's necessary to improve knowledge and local communities' technics on different water control technologies in order to provide irrigation's functions in developing countries. Research efforts on three important concepts are necessary such as : (i) local communities perceptions on crops water need and the responses of differents crops technologies on crops yield ; (ii) interactions between agricultures prospects, water controls innvations and economics benefits of theses technologies.

“…Práticas de uso eficiente da água podem aumentar a viabilidade econômica e a sustentabilidade ambiental da agricultura irrigada, sem necessariamente reduzir o uso da água (LEVIDOW, 2014). Porém, técnicas de tratamento de água, provavelmente pelo uso mais eficiente pelas plantas, podem reduzir a necessidade de água a ser reposta pela irrigação.…”

RESUMO: Para que a irrigação seja uma prática viável, justifica-se adotar práticas que promovam a produtividade, o lucro e a sustentabilidade. O gotejamento tem sido comprovadamente uma técnica que economiza água e insumos. Todavia, problemas relacionados com o entupimento de mangueiras e a precipitação de sais inviabilizam o seu uso em algumas regiões, principalmente onde as águas provêm de rochas calcárias. Dentro deste contexto, surge como uma alternativa o tratamento da água por campo magnético, que é um método sem utilização de produtos químicos ou energia elétrica. Acredita-se que a água tratada utilizada para a irrigação pode melhorar a eficiência de uso pelas plantas, conservando assim o abastecimento para uma futura escassez de água. Este trabalho teve como objetivo avaliar a utilização da água magnetizada no crescimento e produção do cafeeiro irrigado por gotejamento. Após 4 safras consecutivas, concluiu-se que a utilização da água magnetizada promoveu significativos aumentos na produtividade do cafeeiro, de 22 (metade da água aplicada) a 47,5% (toda a água aplicada). Em termos de qualidade, também se verificaram maiores percentagens de frutos cereja nos tratamentos com a utilização da água tratada. PALAVRAS-CHAVE:magnetização da água, gotejamento, economia de água. MAGNETIC WATER TREATMENT FOR IRRIGATION OF COFFEE CULTIVATED IN MINAS GERAISABSTRACT: For irrigation to be a viable practice, it is justified to adopt practices that promote productivity, profit and sustainability. Drip irrigation has been proven to be a technique that saves water and supplies. However, problems related to the clogging of hoses and the precipitation of salts make it unfeasible in some regions, especially where the water comes from limestone rocks. An alternative is the treatment of water by magnetic field, which is a method without the use of chemicals or electric energy. It is believed that the treated water used for

Inappropriate irrigation methods lead to loss much water in most upland fields worldwide. Land suitability is one of the good management practices for determining appropriate irrigation methods in upland fields. To determine land suitability, various soil experiments as determination of basic physical soil properties, permeability, saturated hydraulic conductivity and soil moisture characteristics method are important. This study was conducted on soil experiment with the aim to provide a detailed comprehensive understanding of soil capabilities for applying certain irrigation methods in two upland fields, broccoli field (BF) and tomato field (TF), in Mie prefecture of Japan. Soil physical structure properties, water holding capacity, and hydraulic properties were determined using disturb and undisturbed soil samples on laboratory bases. The results obtained showed that TF had deeper effective soil layer of 30 cm, better structure (more porosity, better pores connectivity, and channeling), the water holding capacity of 0.082 mm mm -1 , and higher hydraulic conductivity, compared to BF. It is concluded that TF is suitable for applying shallow surface irrigation method, while the BF have better response on micro-irrigation methods which prevents water pounding in this fields. Application of this approach can improve irrigation practices and efficiency and decreases water loses through accurate irrigation scheduling and application management of irrigation water in upland field agriculture system, especially in dry areas.
