The ladino clover was transported to the tank in a phytotron and was mowed when it attained optimum growth. The crop.was again allowed to attain maximum growth and again was mowed. Experiments and observations on the evapo-transpiration of the crop were carried out at the time of harvest. The consumptive use of water was measured in Mariotian equipment and the measured volume was converted in water requirement in depth. The quantity of evapo-transpiration after the second mow increased rather rapidly as compared with the first one. It follows from the results of these experiments that both of the evapo-transpiration curves of the crop indicate monotonic increase and are Logistic curves of the form Y=K/(1+me-at) where Y: rate of evapo-transpiration (mm/day), t: time (day), K: The limit value of Y, m; a: constants, e: Napierian base.
