2. It is designed to deliver a constant flow of water among irrigators along a tertiary canal. A constant time per unit irrigated area is allocated to all the farmers regardless of their location along the canal. These results in decreasing volumes of water delivered to downstream farmers. A variable time model is developed which allocates more time to the downstream farmers to deliver a constant volume of water per unit area to all the farmers in the command area of a tertiary unit.
4. India is a large producer of agricultural products. Irrigation resources are limited & the water-use-efficiency as well as agricultural productivity is low.
5. Micro irrigation (MIS) which is the most efficient method of irrigation was introduced in 1987. MIS has become popular in India & it has been adopted on 400,000 ha. The integrated approach evolved by JAIN IRRIGATION (JISL) & the support provide ny various Govt. & other agencies are the main factors for the rapid growth of micro-irrigation in India.
6. For successful implementation of MIS, numerous technical services such as land survey, water & soil analysis, climatological data, design, availability of high quality components, installation, extension & training of farmers as well as after sales customer services, etc. are necessary.
8. It is the delivery of water at low flow rates through various types of water applicators by a distribution system located on the soil surface, beneath the surface, or suspended above the ground. Water is applied as drops, tiny streams, or spray, through emitters, sprayers, or porous tubing.
