Présentation

Globally, the area under irrigation is five times larger today than what it was a hundred years ago. Without irrigation, increases in agriculture to feed the world’s growing population would not have been possible. In addition, as competition for fresh water increases, water of better quality would primarily be used for domestic purposes whereas, water of lower quality would be use for irrigation. Therefore, the challenge for agriculture in the future will be to maintain or even increase crop production with water of lesser quality and increase water use efficiency.

Drip irrigation system has the advantage of maintaining high water content near the plant root and thus enhancing water use efficiency. However, its performance depends on water quality as poor quality water may induce emitter clogging. Use of saline water with appropriate irrigation management techniques might help in achieving long-term sustainability in agricultural in dry areas where availability of good quality water is limited. A study on drip irrigation with low quality water for sustainable production under simulated arid environment was carried out at the Arid Land Research Center, Tottori University, and in the Tohaku National Irrigation Project area, Tottori, Japan (35°32´N and 134°13´) during 2004 and 2006. The study included the following four parts :
