dc.description.abstractThe World’s population is increasing at an alarming rate resulting in increasing demand for food and fiber. On the other hand, per capita availabilityof land and water resources are decreasing. Water is a valuable natural resource, which is used for agriculture, recreation and industrial purpose. Due to industrialization, population growth and urbanization, demand for wateris being increased drastically, which resulted in stress on the water resources. The major portion of the water is used in agriculture sector for irrigation purpose to enhance the crop production. Due to growing demand for household and development purpose the share of the irrigation water needs to be diverted for industries, recreation and drinking purpose. Therefore, it is the need of the hour to effectively utilize the available water resources optimally and judiciously,Irrigation was given major importance in many countries of the world. However there is wide spread dissatisfaction with the performance of irrigation projects in developing countries. In India the performance of irrigation projects is reported to be very low, having an overall efficiency of 25-30 percent only due to lack of proper irrigation water management (Akhilesh et al., 2012). So the existing project and project command areas need to be evaluated for improving their System performance, agricultural production, financial aspects, irrigation efficienciesand water use efficiencies. The present investigations is carried out in Thatipudi medium irrigation project in the district of Vizianagaram, Andhra Pradesh. It was constructed across Gostani River in 1963-68 and it serves 6218.29 ha of command area in Gantyada, Jami and S.kota mandals of Vizianagaram district. The average annual rainfall is 1183 mm.The study area received 64.32 per cent of annual rainfall during South West monsoon season and 23.52 per cent in North East monsoon season and remaining 12.16 per cent during winter and summer seasons. Crop water requirement and water use efficiency for Paddy, Pulses and Banana was estimated 1310.5 mm, 406.5 mm,1435.0 mm and 62.098%, 90.39%, 83.944% respectively. Overall irrigation efficiency for Thatipudi project was estimated as 29.67 %. Reservoir filling or storage efficiency was observed as 96.06 %, Conveyance efficiency was 65.778 % and the application efficiency was 45.581 %. This project was analysed through performance indices which are given by the INCID (Indian National Committee on Irrigation and Drainage).System performance and Agricultural production indices are found ‘good’ condition but the financial aspect indices are ‘very poor’ due to less revenue collection, low operation and maintenance funds and less persons involved for operating the project.Finally water budget was prepared by observing the current storage, average inflowsto the reservoir the Gross water requirement for the crops (81.55 Mm3 ), water supplying for the Greater Vishaka Municipal Corporation (GVMC) (15.17 Mm3 ), leakage through head regulator (4.177 Mm3 ), Water for Domestic and live stock purposes(2.98 Mm3). Key words: Medium irrigation project, Command area, Crop water requirement, Irrigation efficiencies, Performance indicators, Water budget.en_US
