Surface irrigation methods such as borders, round basins, modified round basins and modified furrows were evaluated for the peach orchard at the Water Resources Research Institute Field Station, NARC, Islamabad. The three methods with slope of 0.75% were compared in terms of savings in irrigation water and duration of irrigation against borders with slope of 0.43%. Compared to borders, savings in water application of 486%, 260% and 464% were observed in round basins, modified round basins and modified furrows, respectively. A similar trend was observed in the duration of irrigation. Distribution uniformity was estimated using minimum and average depth of water infiltrated. Distribution uniformity of 59.2%, 81.3%, 92.3% and 76.6%, was observed for round basins, modified round basins, modified furrows and borders, respectively. Therefore, modified furrows can be used to achieve higher uniformity and five times more area can be irrigated for deciduous orchards. This system also provides an opportunity to have better orchard management where transmission of soil borne diseases is much lower compared to other methods. This method was designed where wetted areas is more or less the same as trickle irrigation except the main furrow line. Thus this system is suitable for areas like Balochistan where water is at premium.

This paper describes the feasibility of sprinkler irrigation systems in Pakistan and indicates potential areas of development along with the present state of introduction. The four rainguns selected for local manufacture (indigenization) and manufacturers' specifications are presented. These can be used to design sprinkler systems for farms 2 acres to 15 acres. Similarly, high pressure centrifugal pumps of 2 lps, 4 lps, 6 lps and 8 lps capacity were designed and indigenized in collaboration with MECO Pvt., Lahore. This company now manufactures pumping systems for any configuration of pressure and discharge. The pumping systems are available with electric motor or diesel engine. The estimated installed cost of portable raingun sprinkler systems in Pakistan ranges from Rs.5000 to Rs.6000 per acre for a system of at least 10 acres using diesel-operated pumping system. The cost of electric-operated system is in the range of Rs.3000-Rs.4000 per acre for a system of five acres or more. These systems are simple in operation and all the spare parts are available locally. Low density polyethylene black carbon pipes with UV stabilizers were also developed for 25 mm, 50 mm, 76 mm and 102 mm diameters which can be used for delivery and suction purposes.

During the 1980s many research and developmental organizations exerted efforts to introduce trickle irrigation systems in the country. All these efforts were based on the use of imported materials and were unsuccessful due to higher installation costs and lack of services and skills. PARC was entrusted to promote trickle irrigation technology in the country and to analyze the problems related to the successful introduction of this technology. This resulted in the process of indigenization of trickle irrigation systems in the country using local skills, technology and materials. Accordingly, PARC established the National Irrigation Systems Testing Laboratories of the Water Resources Research Institute, NARC, for research, evaluation and testing of trickle irrigation systems and indigenization. In collaboration with the Plastics Technology Centre (PTC), Karachi and GRIFFON Industrial Corporation, Lahore, PARC successfully completed the indigenization process and commercial production has been initiated. Now the appropriate technology, skills and services are available which will be used in the future for large scale adoption of trickle irrigation in the country. The estimated cost of a standard trickle irrigation system is Rs.9000/acre based on the Ex. Factory price.
