Most of the farmers in Indonesia grow rice in flooded paddy fields using water supply from irrigation canals, either technical or non-technical. With such irrigation system support most of farmers in Indonesia can plant and harvest rice three times a year. However, for areas that do not supported by proper irrigation systems and has a limited water resources, farmers in such areas take the advantages of rainy season for planting and can only harvest rice once a year.
In numbers of places in Java, rain-fed rice cultivation in average produces yields of 9 tons per hectare. In general, farmers planted their rain-fed rice fields with a varieties of seed known as Pioneer P3 with yield that is approximately equal to rice fields that are supported by the irrigation system. Therefore, planting rain-fed rice for more than once a year is something obscure, where drip irrigation technology is the most recommended solution.
Among other Asian countries, India renowned as one of those countries that have been using drip irrigation technology for agriculture, including for rice crops. Especially, in areas that have limited water resources and without support of irrigation system, such as the Rajastan state. Farmers in Rajastan take the advantages of well pump that powered by solar energy to supply water along with the application of Drip Irrigation technology to save water.
