Flat topography, heavy clay soil with low permeability and cracks resulting in high water loss as well as waterlogging after sudden heavy showers hinder farmers' acceptance to basin irrigation for post-rice upland crop. Conventional furrow irrigation technique was not practiced because of high input for land shaping. A new irrigation technique was tested in which water was distributed by furrows at 5 and 10 meters spacings, allowed to overlap the furrows and to flow overland while being infiltrated both horizontally and vertically into root zone. The furrows also removed excess water. Factors affecting the technique including furrow spacings, irrigation frequency, mulching and land preparation were also tested. Economic performance indicators at farm level and farmers' acceptance were analyzed.

Marine and lacustrine deltas around the world are economic and environmental hot spots. They occupy approximately 1% of the Earth's land area but are home to more than 500 million people—a population density more than 10 times the world average [Ericson et al., 2006]—all within 5 meters of sea level [Overeem and Syvitski, 2009]. This high density is supported by high productivity, rich biodiversity, and transport along a network of waterways. Yet deltaic systems are some of the world's most delicate and vulnerable natural systems, residing at the boundary between land and water, and are subject to upstream human control, local resource exploration, and climatic impacts.
