This study aimed to evaluate the left main canal (LMC) of the Bhimsagar medium irrigation project, Jhalawar using adequacy, dependability and equity, and water conveyance and on-farm application efficiency. These indicators calculated for each outlet of selected minors (three minor located at the head, middle and tail section) of LMC during 2016-2017 of rabi season. The ratio of water delivered (measured discharge at each outlet) and irrigation demand (calculated crop water requirement using CROPWAT 8.0 model) for major rabi crops (wheat, mustard, garlic and coriander) grown in the command area. The overall water conveyance efficiency of LMC was found as 77.95%, whereas, for Kherli, Bagher and Badankheri minor of LMC observed as 74.94, 73.55 and 65.89%, respectively. The on-farm application efficiency found at 76.89% in the command area of LMC. The results had shown fair (0.88 to 0.83), fair (0.84 to 0.82) and poor (0.85 to 0.28) gate adequacy indicator (GAI) at head, middle and tail section of the LMC, respectively. All outlets of LMC had shown very ‘poor’ dependability with values ranging from 0.33 to 0.62 (>0.25). Also, there is ‘poor’ equity (CVR) was found for selected minors of LMC as it values varied from 0.01 to 0.44 (>0.25).
