Irrigation is a major input for the development of agriculture in any country, the greatest development in the history of mankind was the discovery of agriculture and then irrigation. Irrigation has been practiced from very ancient times in our country; irrigation assumes paramount importance lest the vagaries of nature and uncertain rainfall lead to ruining of crops resulting in famine conditions. Irrigation serves a dual purpose in agriculture, it provides protection to crops against destructions and damage by failure of rainfall and irrigation helps to increase yield of crops even in normal condition. Hence irrigation is important, without irrigation agricultural production could not increase, but for that water is necessary for practice of agriculture. In India agriculture is carried out with the help of irrigation. Irrigation means supply of artificial means of water, it is one of most crucial inputs in the process of agriculture development, so significant efforts have been made the develop the irrigation potential through the projects. Some time minor irrigation projects play vital role in transforming the agriculture into productive agriculture as well as changing the overall social-economic structure of the area similarly agriculture gets stability also. Hence in this research paper an attempt has been made to how impact on population of minor irrigation project in Warud Tahsils.


The study examined the impact of minor irrigation on agricultural production and evaluated the gap between IPC and IPU in the Keonjhar district of Odisha. For this rationale, data were collected from 210 farm households through the primary survey. In support of the analysis, the Cobb Douglas model and factor analysis were used. The results revealed that the input use efficiency had a positive and significant impact on paddy production the most in all the MIPs regions compared to the other crops. However, the study indicated that insufficient water availability was the major cause behind the gap between irrigation potential created and utilised. Thus, minor irrigation played a crucial role in enhancing agricultural production in hilly regions. With the enthusiastic participation of planners, effective working of Pani Panchayats, canals, and upstream control, NGOs' involvement can achieve selfsufficiency in agricultural production by encouraging minor irrigation projects in the hilly province.

Abstract. Supplemental irrigation of rainfed winter crops improves and stabilises crop yield and water productivity. Although yield increases by supplemental irrigation are well established at the field level, its potential extent and impact on water resources at the basin level are less researched. This work presents a Geographic Information Systems (GIS)-based methodology for identifying areas that are potentially suitable for supplemental irrigation and a computer routine for allocating streamflow for supplemental irrigation in different sub-basins. A case study is presented for the 42 908 km2 upper Karkheh River basin (KRB) in Iran, which has 15 840 km2 of rainfed crop areas. Rainfed crop areas within 1 km from the streams, with slope classes 0–5, 0–8, 0–12, and 0–20 %, were assumed to be suitable for supplemental irrigation. Four streamflow conditions (normal, normal with environmental flow requirements, drought and drought with environmental flow) were considered for the allocation of water resources. Thirty-seven percent (5801 km2) of the rainfed croplands had slopes less than 5 %; 61 % (3559 km2) of this land was suitable for supplemental irrigation, but only 22 % (1278 km2) could be served with irrigation in both autumn (75 mm) and spring (100 mm), under normal flow conditions. If irrigation would be allocated to all suitable land with slopes up to 20 %, 2057 km2 could be irrigated. This would reduce the average annual outflow of the upper KRB by 9 %. If environmental flow requirements are considered, a maximum (0–20 % slopes) of 1444 km2 could receive supplemental irrigation. Under drought conditions a maximum of 1013 km2 could be irrigated, while the outflow would again be reduced by 9 %. Thus, the withdrawal of streamflow for supplemental irrigation has relatively little effect on the outflow of the upper KRB. However, if the main policy goal would be to improve rainfed areas throughout the upper KRB, options for storing surface water need to be developed.
