For optimal use of water resources determination of crop coefficients and water requirement for each region is necessary.The present study was conducted to determine the values of water requirement and crop coefficients of Peppermint (Mentha piperita L.) in a semi arid climate. For this purpose, eight water balance drainable lysimeters were used. For those reasons two lysimeters was used for grass and bare soil evapotranspiration estimation. Also in six other lysimeters, peppermint in two groups A (Plant growth was continued until the end of flowering.) and B (plant harvested three times, after reaching a height of 10-12 cm) was planted. Finally the average water requirement of Peppermint in two lysimeters groups A and B were determined as 664.4 and 566.4 mm respectively. Single and base crop coefficients for lysimeters in group A, for the initial, development and middle stages of peppermint growth were determined as, 0.69 ، 1.03 ، 1.27 and 0.29، 0.86، 1.17 respectively . Also the average of single crop coefficients on first, second and third harvests for lysimeters in group B was determined as 0.84 ، 0.92 ، 0.96 respectively.
