Drip or trickle irrigation is one of the latest methods of irrigation which is becoming increasingly popular in areas with water scarcity and salt problems. The Government of India recognized the importance of micro irrigation and announced subsidy schemes in few selected states in 1991. Different crops require different plant spacings and irrigation requirements. The general layout of the system and the location of the emitters will depend on the type of crop. This paper describes a windows based computer application developed for designing efficient drip irrigation facilities using Visual Basic 6. The concern for an arrangement of this type is justified by the superior advantages offered by drip irrigation compared to other methods. This software is user-friendly and provides interaction at all stages of the design process and a solution based on individual’s requirements and the information base available within the software. The individual not only can suit to his requirement but can also compare his design with several other alternate designs with different inputs. Design of system arrived by this software was tested with manual calculations at developer's level and results were found satisfactory.
